Frere’s Aristophanes. PREFACE THE practice of photographing birds in Nature is of too recent origin in this country to permit of its being treated authoritatively. The methods which may be employed are so numerous, the field to be covered so limitless, that many years must elapse before the bird photographer’s outfit will meet his wants, while the constantly varying details which surround his subjects almost prohibit dupli- cation of experience. But it is these very difficulties which render all the more imperative the necessity of conference among workers in this fascinating and important branch of natural history. The causes of both success and failure should, through the medium of books and journals, be made accessible to all, there- by shortening this experimental stage of the study of birds with a camera, and hastening the day when the nature of the outfit and methods shall have been settled with more or less definiteness. It is as a contribution toward this end, and as a means of answering the queries of numerous corre- spondents, that the following pages, embodying the results of my own experiences, are offered. It is sincerely hoped that they may increase the interest Vil vill BIRD STUDIES WITH A CAMERA in the study of birds in Nature, and at the same time furnish a more profitable and delightful out- let for the hunting instinct than is afforded by the shotgun or rifle. A large proportion of the Bird Rock pictures and several of those from Pelican Island have appeared in the Century and St. Nicholas respectively, and are here reproduced by the courtesy of the editors of those magazines; others have been previously published in Bird-Lore.

A picture of the bird itself is, of course, of the first importance, but any fact in its biography which the camera can be employed to portray is within the province of bird photography. The Scientific Value of Bird Photography.—There are certain matters, such as a bird’s song, its time of migration, etc., which must be set forth with the pen; there are others, such as its haunts, nesting site, nest, eggs, the appearance and development of its young, where the camera is so far ahead of the pen in its power of graphic representation that it is a waste of time to use the former when circum- stances permit the utilization of the latter. A photograph of a marsh or wood showing the favorite haunts of a species is worth more than pages of description. A picture of a bird’s nest- ing site conveys a better idea of the situation than words can possibly give, while in place of such vague phrases as “nest of coarse grasses, weed 2 1 9 BIRD STUDIES WITH A CAMERA stalks, rootlets, etc., lined with finer materials,” we have a faithful delineation of the nest itself. The shape and pattern of markings of the eggs may also be well shown with the camera, while the appear- ance of the young at birth, their development, and often the manner in which they are fed, may all be portrayed by the camera with a realism which con- vinces one of the truthfulness of the result. By the exercise of much patience and ingenuity we may also photograph the adult bird, showing it at rest or in motion, brooding its eggs or caring for its young. Under favorable conditions such pic- tures may possess an exactness of detail which makes them perfect representations of the original, giving not alone position and expression, but the arrangement of the feathers, and they then have scientific value unequaled by the best productions of the artist’s brush or pencil. From the nature of the case, perfection in this branch of bird photography is not always attained; nevertheless, even pictures which are failures from a photographic standpoint may be of interest to the naturalist. They may be lacking in detail and still give pose, thus furnishing models from which drawings containing all structural essentials may be made. The camera may also supply us with graphic records of the few large colonies of birds yet exist- ing in this country, thereby preserving for all time definite impressions of conditions which are rapidly becoming things of the past. What an invaluable addition to the history of the Great Auk would be a series of photographs INTRODUCTION 3 from Funk Island, taken during the period of its existence there! Of what surpassing interest would be photo- graphs of the former flights of Wild Pigeons, which the younger generations of to-day can with diffi- culty believe occurred ! The Charm of Bird Photography.—As a one- time sportsman, who yielded to none in his enjoy- ment of the chase, I can affirm that there is a fasci- nation about the hunting of wild animals with a camera as far ahead of the pleasure to be derived from their pursuit with shotgun or rifle as the sport found in shooting Quail is beyond that of breaking clay “ Pigeons.” Continuing the comparison, from a sportsman’s standpoint, hunting with a camera is the highest development of man’s inherent love of the chase. The killing of a bird with a gun seems little short of murder after one has attempted to cap- ture its image with a lens. The demands on the skill and patience of the bird photographer are end- less, and his pleasure is intensified in proportion to the nature of the difficulties to be overcome, and in the event of success it is perpetuated by the infi- nitely more satisfactory results obtained. He does not rejoice over a bag of mutilated flesh and feath- ers, but in the possession of a trophy—an eloquent token of his prowess as a hunter, a talisman which holds the power of revivifying the circumstances attending its acquisition. What mental vision of falling birds can be as potent as the actual picture of living birds in their homes ? And how immeasurably one’s memories are 4 BIRD STUDIES WITH A CAMERA brightened by the fact that this is not a picture of what has been but of what is! The camera thus opens the door to a field of sport previously closed to those who love birds too much to find pleasure in killing them; to whom Bob- White’s ringing whistle does not give rise to mur- derous speculations as to the number in his family, but to an echo of the season’s joy which his note voices, They therefore have a new incentive to take them out of doors; for however much we love Na- ture for Nature’s sake, there are few of us whose pleasure in an outing is not intensified by securing some definite, lasting result. We are not all poets and seers, finding sufficient reward for a hard day’s tramp in a sunset glow or the song of a bird. Enjoy these things as we may, who would not like to perpetuate the one or the other in some tangible form ? And here we have one of the reasons for the col- lecting of birds and eggs long after the collector’s needs are satisfied. He goes on duplicating and reduplicating merely to appease the almost univer- sal desire to possess any admired although useless object. Once let him appreciate, however, the pleas- ure of hunting with a camera, the greater skill re- quired, and the infinitely greater value of the results to be obtained, and he will have no further use for gun, climbing irons, and egg drill. Furthermore, the camera hunter possesses the ad- vantage over the so-called true sportsman, in that all is game that falls to his gun; there is not a bird too small or too tame to be unworthy of his attention ; nor are there seasonal restrictions to be observed, INTRODUCTION 5 nor temptations to break game laws, but every day in the year he is free to go afield, and at all times he may find something to claim his attention. Finally, there is to be added to the special charm of bird photography the general charm attending the use of the camera. Thousands of people are finding pleasure in the comparatively prosaic em- ployment of photographing houses, bridges, and other patiently immovable objects wholly at the camerist’s mercy. Imagine, then, the far greater enjoyment of successes not only of real value in themselves, but undeniable tributes to one’s skill both as photographer and hunter. Nor should this introduction be closed without due acknowledgment to the educational value of photography, to its power to widen the scope of our vision, and to increase our appreciation of the beau- tiful. There is a magic in the lens, the ground glass, and the dark cloth which transform the commonest object into a thing of rarest interest. THE OUTFIT AND METHODS OF THE BIRD PHOTOGRAPHER THE BIRD PHOTOGRAPHER'S OUTFIT HE beginner must not suppose that good bird photographs can be made only with expensive appa- ratus. Under favorable conditions there is no great difference in the results secured with the ordinary ae camera and lens of any reputable maker and those of the highest class. My own work has for the greater part been done with an outfit costing about thirty dollars; and although the best lens is, of course, to be desired it is not a necessity, and cost therefore is no more an obstacle to the hunting of birds with a camera than it is to their pursuit with a gun. The Camera.—iIndividual taste will doubtless govern the size of the camera chosen, but most natu- ralists and sportsmen consider the camera carrying a plate four by five inches as the one best adapted to their wants, and with this decision I heartily agree. The advantages of size, weight, and economy, both as regards the camera, its holders, and plates, are all in favor of the 4 x 5, while as far as the bird pho- tographer is concerned, it is not often that he has need of anything larger. The image of a bird will rarely be without adequate setting in a space four 6 THE BIRD PHOTOGRAPHER'S OUTFIT tii by five inches, which will also be found to be large enough for the portrayal of nests and eggs. The 4 x 5 also reduces proportionately in making lantern slides, and if the picture is made the long way of the plate—that is, higher than broad—it can be easily adapted for illustrative purposes in duo- decimo or octavo books. When a larger picture is desired it can readily be made by enlargement, an increase in size of three diameters, or six times the area, being possible from a sharp negative without undue loss of definition. For use from a tripod any one of the several ex- cellent long-focus cameras now on the market will be found to answer every requirement. If it is pro- posed to employ a telephoto lens, care should be taken to select the camera combining greatest bel- lows length with rigidity. A reversible back in- creases the size somewhat but adds to the length of bellows, and will be found serviceable in the many awkward situations in which the bird photographer is often placed by the nature of his subjects. The Kearton brothers have an “ adjustable min- iature” on the top of their camera, which they state “is used as a sort of view finder when making studies of flying birds. When fixed in position and its focus has been set exactly like its working com- panion beneath it, both are racked out in the same ratio by the screw dominating the larger appa- ratus.”* The purposes of this attachment, however, * From Wild Life at Home, how to Study and Photograph It, by R. Kearton, illustrated by C. Kearton; a work of the utmost interest to the animal photographer, who should also read With Nature and a Camera, by the same authors (Cassell & Co.). 8 BIRD STUDIES WITH A CAMERA will, it seems probable, be better served by the re- flecting camera described below, while as a finder alone its place may be taken by the “iconoscope ” and other of the prism finders, the brilliant image cast by which is such a striking and satisfactory improvement on the hazy outlines given by the average so-called “ finder.” For use as a hand-box only two kinds of camera are available, for it must be borne in mind that the set-focus or short-focus, wide angle “snap-shot” cameras, so popular among the button-pressing fra- ternity, are not adapted to the wants of the bird photographer, who must therefore avail himself of either a twin-lens or a reflecting camera. Twin-lens cameras are manufactured by several well-known firms, but the trade size is of too short focus to be desirable. In this type of camera two lenses of equal foci are employed. They are set one above the other in bellows, which move as one. The lower lens makes the picture, the upper projects a duplicate of the image cast by the lower lens to a mirror set at an angle of forty-five degrees to the plane of the plate, whence it is reflected upward to a ground glass, which is protected by a hood, on top of the camera. To focus perfectly the lenses should be “matched ” or “paired”—in short, interchangeable—thereby greatly increasing the cost of the camera, which is also rendered objectionable by its large size. The reflecting camera possesses all the advan- tages of the twin-lens, but requires only one lens, and when in use is not materially larger than the ordinary 4 X 5 long-focus box. ‘ THE BIRD PHOTOGRAPHER'S OUTFIT 9 The reflecting camera now in my possession was designed and made by John Rowley, of the Ameri- can Museum of Natural History, and was fully de- scribed and illustrated by him in Bird-Lore for April, 1900. It resembles the upper half of the twin- lens camera in that a mirror, set at an angle of forty-five degrees to the plate, is interposed between the latter and the lens, and reflects its image to a ground glass on top of the camera. This mirror, however, is movable, and the desired object appear- ing in focus on the ground glass, a lever is pressed downward which raises the mirror to the top of the box, where it automatically releases a focal-plane shutter (see beyond, under The Shutter) directly in front of the plate, when the image-bearing rays, be- fore intercepted and reflected by the mirror, are registered on the plate, from which the slide had previously been drawn. When the focal-plane or curtain shutter has been set and the slide drawn from the plate holder, this camera is like a cocked gun, which may be fired the moment it is sighted; or, in other words, the ex- posure may be made the instant focus is secured. With this camera one may take advantage of any offering opportunity to secure a picture of a bird or beast when afield, and this fact, by increasing the possibilities of an outing, adds greatly to its pleasure. Mr. Rowley has so designed this camera that it may be used from a tripod as well as in the hands; but when the tripod camera is to be left, perhaps for hours, hidden near some bird’s nest, I prefer to employ the long-focus for this purpose, and retain 10 BIRD STUDIES WITH A CAMERA the reflecting camera for possible use on the birds that so often approach closely when one is in hiding. The advantages possessed by this camera are so ap- parent that it doubtless will soon be placed on the market. The Lens.—Professional photographers differ so widely in their opinions of the relative qualities of the various makes of lenses now on the market, that I approach this subject with diffidence, and, without presuming to offer advice, present the results of my experience both as to lenses and the requirements of the bird photographer. In regard to the latter phase of the much-discussed question of “ What lens shall I use?” I may speak with more confidence. For nests with eggs or young birds—subjects which may be approached closely—a six- to eight-inch-focus lens forms a large enough image, and at the same time gives depth of focus and sharpness of definition without the use of the smaller diaphragms. In pho- tographing birds, however, it is generally difficult to get within “shooting” distance, and at least a fourteen- to sixteen-inch lens is needed in order to secure an image of sufficient size. Depth of focus is here, in my opinion, not desirable, and the focal point—the bird—is brought out more clearly by the fusion of all the objects back of it into a uniform background. When a bird, either young or old, is the subject, great speed may be required, and sometimes under light conditions which severely test the qualities of the lens. To fully meet these demands of distance and time two lenses would be needed; but, aside from the increased cost and the inconvenience of THE BIRD PHOTOGRAPHER’S OUTFIT 11 using two lenses, the great size and weight of a long-focus lens are drawbacks. These objections are largely overcome by the use of the symmetrical lenses placed in most of the long-focus boxes, or, if expense be not considered, by a “convertible” lens. For several years I have used a “ Victor” lens, sold with the “Premo” long-focus camera. The combined focus of the front and back lenses is seven and a half inches, of either of the lenses alone, fif- teen inches. The single lens therefore, the distance being the same, gives an image double the size of that cast by the two lenses together. This lens has been thoroughly tested, and many of the pictures given in this book were made with it. When the conditions are favorable and the subject not extremely difficult it yields satisfactory results. The “convertible” lenses of various makers are also separable, and where the rear and front lenses are of different foci three focal lengths are obtain- able. These lenses are of the highest grade, and consequently expensive. In a bright light, or where great speed is not required, they do not seem to be as superior to the trade lens as the much higher price would lead one to expect. But in dull days, or in the shadow, or where extremely rapid exposures are necessary, their superior qualities become evi- dent. My experience with these convertible lenses has been limited to the Zeiss Anastigmat, Series VII a, of which I am now using a No. 10 with a combined focus of eight-inches, the front and rear lenses both having a focal length of fourteen inches. This combination is preferred to one in which the component lenses are of different foci, because of the 12 BIRD STUDIES WITH A CAMERA greater speed of the two when combined, and fur- thermore, because, being of the same focus, they could, if occasion arose, be used in a twin-lens box. The speed of the combination is registered at F. 6.3; that of the single lenses at 12.5. With the former the most rapid exposures can be made successfully, while the latter are sufficiently fast to permit of ordinary instantaneous work. This lens is stated to cover a 5 X 84 plate, and when in use on a 4X 5 camera gives a high degree of illumination and per- fect definition. The telephoto lens may be employed in certain kinds of bird photography with not unsatisfactory results. Its disadvantages are lack of speed, an ex- posure of at least one half a second to a second being required at F. 8 in bright sunlight, the necessity of extreme care in focusing, and of absolute rigidity of the camera at the time of making the exposure. In short, the telephotographer needs more time, both before and after pressing his bulb, than the bird photographer is often accorded. However, with such subjects as nests high in trees or on cliffs, Herons and other shore-inhabiting birds, Ducks on the water or Hawks perched in leafless trees, the telephoto will be found serviceable. Negatives are frequently secured in which the figure of the bird, while small, is sharp, when, by enlargement, a desirable picture can be made of what in the original was too small to be easily dis- tinguishable. An increase in size of two diameters is possible from any fairly sharp negative, but if the object be in perfect focus an increase of four diame- ters may be made. THE BIRD PHOTOGRAPHER'S OUTFIT 13 These enlargements may be made with an en- larging camera or with the aid of a Nehring enlarg- ing lens, which is placed between the front and back lenses of the view lens, when, with the ordinary long-focus camera, a magnification of about four diameters may be obtained, the image being thrown on to a piece of bromide paper in the plate holder. Through enlargement many apparently worth- less negatives become of value, and in some in- stances pictures can be made from different parts of the same negative. From the sportsman-photog- rapher’s standpoint there is, however, one objection to the use of a magnifying lens. It gives deceptive results, and those who are not familiar with its powers are apt to accord the photographer undue praise for his apparent skill in successfully ap- proaching some bird or beast which may have been far out of range. A not wholly unrelated kind of enlargement is sometimes applied to the contents of creels and game bags! But the animal photographer is so heavily handi- capped that in this case the end assuredly justifies the means. As a matter of information, however, it seems eminently desirable to accompany all enlarged pictures by a statement of the extent of their mag- nification, and throughout this book this plan is fol- lowed. Consequently, when there is no mention of enlargement, it may be accepted as a fact that the print from which the reproduction was made was obtained from the negative by contact. In illustration of these suggestions in regard to the proper lenses for bird photography, a series of pictures is presented which shows the results to be 14 BIRD STUDIES WITH A CAMERA obtained under the same conditions with different lenses.

The bird in Test No. 1 enlarged about three diameters. mentioned that in the “ Unicum” shutter employed exposures of a so-called “44,” and “35” seconds gave exactly the same results both with the combined eight-inch lens and the front fourteen-inch lens; the actual time, however, was doubtless not far from #5 of a second. The negatives, therefore, show, in the first place, that the long-focus lens is capable of doing fairly rapid work, Continuing our compari- 16 BIRD STUDIES WITH A CAMERA son, we observe that the eight-inch gives a fairly wide field, excellent depth of focus, but a very small image of the bird, for which alone the picture has been made. With the fourteen-inch we decrease the 4. Lens Test No. 2. Same subject, distance, plate, and date as Test No. 1.

This, however, has been done at the loss of depth of focus, not even the first of the line of posts running directly into the THE BIRD PHOTOGRAPHER'S OUTFIT aL background being sharply defined, while with the eight-inch all are in focus.

It practically restricts the picture to the immediate surroundings of the bird, and is without focal depth. Having now made three good negatives in the field, we may, by enlargement, improve on the image of the bird obtained. The possibilities in this direc- tion are clearly shown by the three enlargements oO 18 BIRD STUDIES WITH A CAMERA accompanying the contact prints from their respec- tive negatives. In each instance the enlargement is about three diameters, and the telephoto negative of course furnishes the most satisfactory picture. 9. Lens Test No. 3.

When the difficulties of telephotography are consid- ered, however, and the 3-second exposure of the fourteen-inch lens, which permits of hand work, is compared with the one second of the telephoto, we believe that for general work in photographing THE BIRD PHOTOGRAPHER'S OUTFIT 19 birds a lens having a focal length of at least four- teen inches will be found the most satisfactory. It should be added that, in order to make them wholly comparable, the three contact prints as well 4. The bird in Test No. 3 enlarged about three diameters. as the enlargements were made on enameled bromide paper. The Shutter—For fairly rapid, slow, and time exposures, a lens shutter, such as is sold with trade cameras, will be found suitable. Simplicity and noiselessness are the chief requirements in this kind of ashutter. The “Iris Diaphragm” shutter is noise- 90. BIRD STUDIES WITH A CAMERA less when used for slow exposures of two or three seconds, a matter of much importance in making time pictures of sitting birds, who are apt to turn their head if they hear the click of the shutter. This shutter, however, does not respond quickly in slow exposures and is very heavy, a disadvantage in tele- photography. The “ Unicum” shutter is lighter, responds quick- ly, has a lever to which a thread may be attached for making exposures from a distance, can be easily diaphragmed from the rear, but is not wholly noise- less. There are also other shutters, each possessing good points of its own, and the selection of any one of them for use in medium rapid, slow, or time work can be left to the photographer, who should, how- ever, remember that the time scales on these shutters represent degrees of difference and not exact meas- urements of time, and that there is great variation in the exposures of different shutters of the same make when similarly adjusted. Thus the “one fifth of a second” of one shutter may be equivalent to the “ one second” of another. The scale on most of these shutters calls for a speed not exceeding a zt> part of a second, but this is far too slow an exposure to successfully photograph a flying bird at short range where a speed of at least 34, of a second is required. For very rapid work the choice is limited to one kind of shutter—that is, the focal-plane, which in effect is a curtain with an adjustable slit which is placed directly in front of the plate. Great speed with this shutter is in part secured by increasing the tension of the spring, which acts as its motive THE BIRD PHOTOGRAPHER’S OUTFIT 91 power, but more particularly by decreasing the width of the slit. Assuming, therefore, that it takes one second for the slit to pass from top to bot- tom of a plate four inches high, and that the slit is one inch in width, it follows that each portion of the plate is exposed to the light for a quarter of a second. Decreasing the width of the slit one half, proportionally reduces the time of the exposure, and by this means, in connection with an increase in the speed with which the curtain is moved, an ex- posure of zyoo of a second is possible. In addition to possessing the advantage of great speed, this shutter also passes a higher percentage of light than a lens shutter even when the actual time of the so-called exposure is the same. This is due to the fact that the lens opening is in no way af- fected, it being the same throughout the exposure. With a lens shutter, on the contrary, the full value of the opening is given for only a fractional part of the exposure, the parts of the shutter more or less filling the opening during the rest of the time. With a focal-plane shutter, therefore, one may do rapid work under conditions where a lens shutter could not be successfully employed; time exposures, however, can not be made with the focal-plane shutter, and for all-around work the camera should be fitted with both a lens and a focal-plane shutter. The reflecting camera, as before stated, is fitted with a focal-plane shutter, and, as described, it is released by pressing the lever, which raises the mir- ror. Lens shutters, however, are released by a pneumatic bulb, or in some cases by a thread or 22, BIRD STUDIES WITH A CAMERA string. When the exposure is to be made from a distance as much as one hundred feet of tubing may be employed. With any length of over twenty-five feet an extra large bulb is required. The ordinary tubing sold by photographers will not be found so well adapted to long-distance work as a less elastic kind, which does not so readily yield to pressure and transmits a larger portion of the force applied when squeezing the bulb. The Tripod.—A_ stout two-length tripod is to be preferred to one of the slender multifolding type, in which stability is sacrificed to weight and size. The legs, except the inner sides of the upper section into which the lower section slides, and brass work should be painted bark color in order to make them as in- conspicuous as possible. For use in the water a metal tripod will prove more serviceable than one of wood. A very useful substitute for a tripod is the “Graphic” ball-and-socket clamp designed more especially for bicycle camerists. With it a camera can easily be attached to the limb of a tree, rung of a ladder, or, by screwing a block on to the head of the tripod, it may be employed in connection with the tripod—in fact its applicability will be evident to every one using it. Plates—Among the many excellent brands of plates now offered to photographers there is really very little difference. However, it is advisable to select the one you think the most rapid and use it to the exclusion of all others. Under certain cir- cumstances—in photographing Robins, for instance —isochromatic plates will be found desirable, and THE BIRD PHO'TOGRAPHER’S OUTFIT 23 where a strong head light can not be avoided non- halation plates may be employed. So much industry, skill, and patience are gener- ally required of the bird photographer before he makes an exposure that he should guard against all chances of failure from the photographic side. It is therefore advisable to thoroughly test plates which it is probable may be exposed on a very difficult subject. Under no circumstances should the plate holders be needlessly exposed to the ight, and when the camera is to be left for an indefinite period with the slide drawn from the holder and plate ready to expose, it should be carefully wrapped in the dark cloth. Blinds.—As the sportsman constructs blinds in which he may conceal himself from his prey, so the bird photographer may employ various means of hiding from his subjects. The Keartons recommend an artificial tree trunk for use in wooded places and an artificial rubbish heap for open fields. The former may be made of lght duck, painted to resemble bark, and placed over a frame. The frame of the Keartons’ is of bamboo, but I find white pine answers very well, the main things to be considered being lightness and portability. The frame should therefore be collapsible in order that it may be easily packed. The Keartons’ field blind or “rubbish heap ” con- sists of an umbrella, to each of the ribs of which strips of bamboo four feet in length are tied. This is then covered with light brown holland and wisps of straw tied over it in such a way as to “ virtually thatch the whole structure.” Doubtless cornstalks 94 BIRD STUDIES WITH A CAMERA properly arranged would make an excellent field blind. It is difficult to carry one of these blinds in addition to a camera, etc., without assistance, and I fear that the inconvenience attending their use will restrict them to the few enthusiasts who count neither time, labor, nor cost in attaining a desired end. For my own part, I prefer, when possible, to con- ceal my camera and make the exposure from a dis- tance rather than to weight myself with a portable blind and to endure the discomforts of being con- fined within it. Sundries.—The bird photographer will find that he requires numerous articles not usually to be found in the regulation photographic outfit, as, for exam- ple, climbers for ascending trees and stout cords for hauling the camera up after him; a dark-cloth, green in color, to aid in disguising the camera, and a mir- ror. The latter should be of plate glass, and meas- ure at least twelve by ten inches. A good plan is to buy a piece of glass of desired size and frame it sim- ply in white pine. It may then be attached to a limb, a stick driven in the ground, or other conven- ient object, by means of the ball-and-socket clamp mentioned under Tripods, which may be screwed into the back or the outer border of the frame. Sucha mirror will reflect sunlight many yards to shaded nests, where, in photographing old or young birds, a quick exposure is necessary. A vest-pocket mirror, for use in reflecting the reading of the diaphragms or time on the shutter, will permit one to make the desired changes from the rear, and thus prove help- THE BIRD PHOTOGRAPHER'S OUTFIT 95 ful when conditions do not permit one to work in front of the camera. A device which might be arranged on the princi- ple of a trap, the trigger to be sprung and exposure made when the bait is taken, would doubtless cap- ture some interesting pictures. An apparatus con- nected with an automatically fired flash-light, has been employed by Mr. G. A. Shiras, of Pittsburg, in photographing deer at night, with phenomenal suc- cess. The connection with the camera shutter was so made that the deer, in walking, touched a cord which exploded the flash-light, and, at the same mo- ment, made the exposure. The light weight of most birds, however, requires a much more delicate appa- ‘atus, While an even greater difficulty is found in the movement caused by the release of the trigger, which startles the bird just as the exposure is made. Thus far in my experiments I have been unable to overcome these objections, but I trust some other bird photographer will be more successful. Those who are ambitious in the direction of cliff photography I would refer to the Keartons’ admi- rable treatise on the subject in their Wild Life at Home, for a description of the paraphernalia needed and the manner in which it should be used. My own experience in this line is limited, and I confess to the utter absence of a desire to increase it! THE METHODS OF THE BIRD PHOTOGRAPHER JLAIMING no special knowledge of the technique of pure photogra- phy, I would refer the beginner to any of the several excellent books designed to explain the rudiments of optical and chemical photogra- phy, and to instruct in regard to the matters of exposing, developing, printing, etc. Only such suggestions are given here, therefore, as relate directly to the manner in which birds, their nests, eggs, and haunts may be photographed. Haunts.— Photographs of the characteristic haunts of birds should show not alone general to- pography, but should also be made with special ref- erence to the bird’s feeding habits, which, more than anything else, govern the nature of the locality selected. Thus, a photograph of the home of the Woodcock would have added value if, in the imme- diate foreground, the “borings” made by this bird in probing the earth for food were evident; or a marsh scene, in which wild rice was conspicuous, would tell something of both the haunts and the food habits of the Reedbird and Red-winged Black- bird in August and September. In a similar way, pictures of wild cherry and dogwood trees, of bay- berries and red cedar, which show both fruit and 26 THE METHODS OF THE BIRD PHOTOGRAPHER 97 surroundings, are of interest in connection with the biographies of many birds. Seasons.—The camera permits us to make so ex- act a record of the rise and fall of the year, as it is registered by vegeta- tion, that we can actu- ally compare existing conditions with those which prevailed at any previous time. Com- pare, for example, the series of four pic- tures*" here presented, all made from the same &, Sonia point of view, in order to appreciate how graphically seasonal changes may be shown by the camera. In this instance, photog- raphy is of more service to the botanist than to the ornithologist ; but every student of migration knows how closely related are the appearance of cer- tain birds and flow- ers, and will readily appreciate, therefore, the value of a series of photographs of sev- eral different subjects, taken at short inter- vals, and showing the changes in vegetation due to the approach of sum- mer or winter. In connection with such related phenomena as temperature, rainfall, and weather, these pictures form as accurate a record of the sea- 9. Summer. 98 BIRD STUDIES WITH A CAMERA sons as it is possible to make, and if data of this kind could be brought together from many selected localities, we should have an admirable basis for the intelligent study of certain phases of bird migration. Nests and Hggs.— The photographing of nests is one of the sim- ,. pler forms of bird pho- , tography, but in many instances success is achieved only through the exercise of much patience and ingenuity. 10, Autumn. It should constantly be borne in mind, in photographing nests, that what is desired is not so much a picture of the nest alone as one which shows it in relation to its environment —in short, a picture of the nesting site is of more value than one of the nest only. It is advis- '/ \ able, however, to make ne ee ~“.\| at least three pictures, Bye two’ 78 of which shall show the nature of the locality chosen, the other“ the character Oi a oo of the nest and its im- 11.

When on the ground it will sometimes be found helpful to put what naturally would be the rear THE METHODS OF THE BIRD PHOTOGRAPHER 99 leg of the tripod forward, between the other two, when it will serve as a brace from in front, and per- mit the camera to be tilted well downward without danger of its falling. Nests at an elevation of seven or eight feet, in saplings, may be photographed by lengthening the tripod with short legs, each supplied with two sta- a 12.

For photographing nests in trees the “Graphic” ball-and-socket clamp is of great assistance. With it the camera may be attached to a limb, or, if the limb is too large, a block may be nailed to it, thus 80 BIRD STUDIES WITH A CAMERA furnishing a grip to which the clamp may be fas- tened. Nests should be photographed from the side, but _ 13, Nesting site, nest, and young of Marsh Hawk. . eges should be photographed from above in order to show their position in the nest as they were ar- ranged by the incubating bird. The nest should THE METHODS OF THE BIRD PHOTOGRAPHER 3] therefore never be tipped, nor should the eggs be touched, lest the value of the subject be destroyed. The markings of most birds’ eggs are already well known, but if photographs of them are desired they can be made from the thousands of eggshells with which ill-directed effort has stocked the cabinets of misguided odlogists. 14, Young Marsh Hawks and nest. It is not advisable to make photographs of nests in the sunlight, a diffused light giving greater de- tail. A screen of some thin white material should therefore be used as a shade when photographing nests exposed to the direct rays of the sun. This, however, will not be found necessary if the picture be made within two or three hours after sunrise, 32 BIRD STUDIES WITH A CAMERA when the light is soft and the foliage comparatively motionless, permitting the use of a small diaphragm and a long exposure. Young Birds.—The ease with which photographs of young birds may often be secured, the fact that with the camera their appearance and development may be more satisfactorily recorded than in any other way, makes their study by the photographer of exceeding importance. Photographs of young birds should of course be accom- panied by notes on food, calls, special actions, etc., which the camera can not well portray. The young bird is a worthy subject from the moment it leaves the shell until, as far as 15. Young Great-erested Flycatcher. flight is concerned, it deserves to be ranked with its elders. When possible, series of pictures should be made showing the rate of growth of the same brood from the period of hatching to the date when the nest is deserted. Circumstances do not, however, often permit of the forming of these ideal series, and we must therefore photograph the young bird as we find him, either before or after he has made his initial flight, or as he is preparing for it.” The suggestions made under the head of Birds’ THE METHODS OF THE BIRD PHOTOGRAPHER 33 Nests and Eggs will apply in a general way to pho- tographing young in the nest; but even when at rest in other respects, the rapid respiration of nest- lings requires a quick exposure to insure sharpness of outline, and, when in the shadow, sufficient illu- 16. Young Baltimore Orioles and nest. mination can be secured only with the aid of a reflector. Adult Birds.—It is in photographing birds in the full possession of the powers of maturity that the bird photographer’s skill and patience are put to the most severe tests. It might be said that, from a strictly ornithological point of view, the results obtained do not in many instances justify the time expended. Success, however, in this field, as in many others, is not to be measured by the attainment of a certain end, but often by the experience gained in what, to one having only the ultimate object in view, may seem to have been fruitless effort. + 34 BIRD STUDIES WITH A CAMERA In matching one’s ability as a hunter against the timidity and cunning of a bird, relations are estab- lished between the photographer and his subject which of necessity result in their becoming inti- mately associated. Doubtless we shall never know just what birds think of the peculiar antics in which the camera 17. Wood Thrush on nest. enthusiast sometimes indulges, but certain it is that an attempt to photograph some of the most familar and presumably best-known birds will open the photographer’s eyes to facts in their life histories of which he was previously in utter ignorance. THE METHODS OF THE BIRD PHOTOGRAPHER = 35 As a known and fixed point to which the bird may be expected to return, the nest offers the best opportunity to the bird photographer, and photo- graphs of adult birds on or at their nests are more common than those taken under other conditions.” * Birds vary greatly in their attitude toward a camera which has been erected near their homes; some species paying little attention to it, and, after a short time, coming and go- ing as though it had always been there, while others are sus- picious of any object which changes the appearance of their surroundings. With the latter special precautions are necessary, and unusual care should be taken in working about their nests lest they be made to desert it. The long-focus lens is here of great service, for it enables one to secure a suf- ficiently large image from a distance of ten or twelve feet. Even then it will often be necessary to con- ceal or disguise the camera by covering it with the green dark-cloth, vines, and leaves. A rubber tube or thread of requisite length is then attached and the exposure is made from a distance. A dummy camera, composed of a box or log wrapped in a green cloth and placed on a tripod 18. Chestnut-sided Warbler on nest. 36 BIRD STUDIES WITH A CAMERA made from saplings, may sometimes be erected to advantage several days before one expects to attempt to photograph the bird, who in the meantime be- comes accustomed to it and quickly returns to the nest after the real camera has been substituted. The artificial tree trunk would doubtless be of assistance in some kinds of bird-at-the-nest photog- raphy, especially when one desired to secure pictures of the old bird feeding its young, and was obliged therefore to make the exposure at just the proper moment. In most instances, however, there is suffi- cient undergrowth in the immediate vicinity to afford concealment, from which with the aid of a glass one may take note of events. With the reflecting camera one may stalk birds on foot or with a boat, or “ squeak” them into range by kissing the back of the hand vigorously, a sound which, during the nesting season especially, arouses much curiosity or anxiety in the bird’s mind. The decoys, blinds, batteries, sneak boxes, etc., of the sportsman are also at the disposal of the hunter with a camera, though I must admit that my one outing to photograph bay birds over decoys resulted in an empty bag. It was in the spring, however, when the bay birds surviving had experienced two shooting seasons and were exceedingly wild. In the fall, with birds born the preceding summer, one might be more successful. Birds may be sometimes brought within range of the camera by baiting them with food, and, after they have learned to expect it, placing the camera in suitable position. This may be most easily done when there is snow on the ground, at which THE METHODS OF THE BIRD PHOTOGRAPHER = 37 time hunger makes most birds less suspicious of danger. From a considerable experience which, through poor equipment, has not yielded adequate return, Tam convinced that one may secure excellent pictures of many birds by decoying them with either a mounted 19. Catbird scolding. or living Owl; doubtless the latter would be prefer- able, though I have never tried it. With a poorly mounted Screech Owl, however, I have had some excellent opportunities to photograph. My plan is to select some spot where birds are numerous, pref- erably near the home of a Catbird,” place the Owl in a conspicuous position, and erect near it a “ scolding perch,” from which the protesting bird may con- 38 BIRD STUDIES WITH A CAMERA veniently vituperate the poor unoffending little bunch of feathers with its staring yellow eyes. The camera is then focused on the scolding perch and the photographer retires into the undergrowth, and, bulb in hand, waits for some bird to take the desired stand. A Catbird’s domain is chosen for the reason that this species is the alarmist of whatever neighbor- hood it may inhabit, and once its attention has been attracted to the Owl by “squeaking” or uttering the alarm notes of other birds, the photographer may subside and let the Catbird do the rest. The bird’s rage is remarkable, its fear painful. Should the Owl be near to the Catbird’s nest it will utter notes in a tone of voice I have never heard it use on other occasions. It loses all fear of the camera, and from the scolding perch screams at the Owl with a vehemence which threatens to crack its throat. One is glad to remove the offending cause. Other birds in the vicinity are of course at- tracted, and hasten to learn the meaning of the uproar. Often a bit of undergrowth, of which the Catbird was apparently the only feathered tenant, will be found to possess a large bird population. It is interesting to observe the difference in the actions of various birds as they learn the reason of the dis- turbance. On the whole, each species displays its characteristic disposition in a somewhat accentuated manner. The Blue-winged Warblers flit to and fro for a few moments and then are gone; the Chestnut- sided Warbler is quite anxious; the Maryland Yel- low-throat somewhat annoyed; the Ovenbird decid- edly concerned; the Towhee bustles about, but THE METHODS OF THE BIRD PHOTOGRAPHER 39 seems to pay no especial attention to the Owl; the Wood Thrush utters its sharp pdt-pit, but is con- tent to let well enough alone if its own nest be not threatened; and the Yellow-throated, Red-eyed, and White-eyed Vireos, particularly the latter, add their complaining notes to the chorus of protests. Not one, however, approaches the Catbird in the force of its remarks, nor does the bird cease to outcry so long as the Owl is visible. It is felt that in the foregoing suggestions the methods which may be employed by the bird pho- tographer are very inadequately described, but, as was remarked in the preface of this volume, the con- stantly varying circumstances attending his work practically prohibit duplication of experience. In truth, herein les the great charm of animal photography. We have not to follow certain for- mul, but each subject presents its own individual requirements, making the demands on the natural- ist’s skill and patience limitless and success propor- tionately valuable. BIRD STUDIES WITH A CAMERA BIRD PHOTOGRAPHY BEGINS AT HOME HE influence exerted by the camera in creating new values for the bird student is perhaps nowhere more evident than in the imme- diate vicinity of one’s home. Even the view from our windows possesses fresh significance as we speculate on the probability of securing a desirable picture from this or that point of vantage, while birds to which long familiarity has partially dimmed our vision now become possible subjects for our camera, and we find ourselves observing their movements with an alertness before unknown. In my own case, I have learned almost to tolerate the House Sparrows, with which I have been at war as long as memory serves me, for the pleasure found in attempting to outwit these shrewd, independent, impudent rats among birds; and, on closer acquaint- ance, they prove such interesting subjects for study that, if their vocal ability equaled their intelligence, they might be as generally liked as they are hated. So much for the magic of a sweet voice. As it is, they possess a greater variety of notes than they are generally credited with, and their conversational powers undoubtedly exceed those of many accom- 40 BIRD PHOTOGRAPHY BEGINS AT HOME 41 plished singers. In addition to the insistent, reiter- ated chissick, chissick, which constitutes the song of the male, one soon learns to recognize calls of warn- ing, alarm, flight, battle, and the soft whistle which the bird utters when it approaches its nest—the only musical note in its vocabulary. Quick to noti¢e the slightest deviation from nor- mal conditions, House Sparrows are difficult birds 20. House Sparrows and Junco, to photograph. They seem to be constantly on the watch for some sign of danger, and an unusual ar- rangement of blind or shade at once arouses their suspicions. After a heavy fall of snow, however, hunger dulls the edge of their fears, and by scatter- ing food near a suitable window the birds may be decoyed within photographing distance.” It will be found necessary, even then, to conceal the camera, 42 BIRD STUDIES WITH A CAMERA which they evidently distinguish from familiar pieces of furniture and regard with alarm. This, too, is the best time to secure pictures of Juncos,” Chickadees, Nuthatches, Downy Woodpeck- ers, Blue Jays, and less common winter birds. The four last named are rarely or never seen about my home in winter. Doubtless the abundant and sur- rounding woodlands afford them a more congenial haunt, from which they are not to be enticed by suet, bones, or grain; or, more likely still, the custom of putting out food for birds is so unusual in the region about New York city that they have not yet learned to expect it. It is a most pleasing surprise to the 21. Junco. x 3. resident of this section to observe the numbers and familiarity of winter birds in the environs of Boston, where a feast seems spread for them in nearly every dooryard, BIRD PHOTOGRAPHY BEGINS AT HOME 43 To return to the Sparrow. The bird’s nest also provides a focal point for the camera, but, as else- where, the greatest precautions must be taken, and I have succeeded in secur- ing a picture only when some advan- tageously situated window afforded a natural blind. One of the pictures thus obtained shows a nest in the orna- mental part of a gutter, with the fe- male looking from an adjoining open- ing.” This gutter seems especially de- signed to furnish lodgings for Spar- rows, and no ar- gument that I have thus far advanced has convinced them that it was not erected for their use. During the early part of their occupancy, a rap on their roof promptly brought them out to perch in the branches of the neighboring trees, where their chattering protest was soon interrupted by a gunshot; but the survivors quickly learned the meaning of the roof tap, and now, without a moment’s pause, they dive downward from their doorway and fly out of range at topmost speed, i 22. Female House Sparrow and nest. x 3. 44 BIRD STUDIES WITH A CAMERA More welcome tenants than the House Sparrows are a pair of Screech Owls, who for years have reared their broods in a dovecotelike gable, where they are beyond the reach of nest robbers of all kinds. During the winter they apparently are ab- sent, uor indeed are they seen until June, when, each evening at sundown, one of the pair, probably the 23. Sereech Owl. x 3. male, takes his post at the entrance to its home and gives utterance to the crooning refrain which some- times follows the so-called tremulous “ screech.” But the latter I never hear at this season. In spite of the poor light prevailing at this hour, the bird’s stillness has tempted repeated trials to secure its picture, and the most successful, made with a four- BIRD PHOTOGRAPHY BEGINS AT HOME 45 teen-inch lens and an exposure of fifteen seconds, is here shown.* Telephotos have thus far been under- exposed, Asa means of making the exposure as soon as possible after the Owl appeared, I have on a num- ber of occasions placed my camera in position, fo- cused and otherwise made ready some minutes before he was expected, and I recall with amusement the incredulity of a friend whose surprise at seeing me point my camera skyward without ostensible purpose was in no way lessened when I told him that I had an appointment with an Owl, who was to take his stand shortly in the hole toward which the camera was directed; and fortunately the bird was on time! From the perch, some forty feet aloft, the grave little creature surveys the scene below with an ex- pression of combined wisdom and thoughtfulness which makes a laugh seem wanton foolishness. At the border of dusk and dark he flies out to feed, often descending to the ground and remaining there for some moments while catching insects. Occa- sionally he takes his prey from the tree trunks, per- haps a cicada struggling from its shell, and on sev- eral occasions I have thought he captured food on the wing. Sometimes the supper hunt leads him to the edge of the croquet lawn, where from the earth or the back of a garden bench he becomes an inter- ested spectator of the last game. When the young appear, later in the month, the evergreens seem alive with Owls, who flit about and utter querulous little calls difficult of description. Toward the end of July, doubtless after the molt is completed, presum- 46 BIRD STUDIES WITH A CAMERA ably the adults—for never more than two are heard— begin to sing ; and this habit of post-nuptial singing seems not to be confined to the Screech Owl, for about this time the deep-toned, resounding notes of the Barred Owl come up from the woods. Through- out August and September the wailing whistle, which is ever welcome for its spirit of wildness, is heard nightly, and as the plaintive notes tremble on the hushed air we invariably say, “ Hark, there’s the Owl!” My experience as bird photographer about home, I must admit, has consisted chiefly in a series of en- couraging failures which have borne no tangible results. Let us hope, however, that the few pictures here presented will prove as suggestive to the reader as they are to their maker, who, although he offers such inadequate proof in support of his belief, is far too well convinced of the possibilities of home pho- tography to go afield without saying at least a word in its behalf. THE CHICKADEE A Study in Black and White (yaeRY early in my experience as a hunter I became acquainted with a small black-and-white bird, who not only announced himself with unmistakable distinctness, but did so at such close range that one could form a very clear idea of his appearance; and thus because of his notes and trust- fulness I learned to know the Chickadee by name years before I was aware that the woods were tenanted by dozens of other more common but less fearless birds. With regret for the universality of the instinct, I found that to see was to desire. I had felt exactly the same longing in regard to other birds, and had thrown many a stone in a fruitless effort to get pos- session of the half-mysterious wild creatures which always eluded me; but the Chickadee came within range of my bean-shooter and soon paid the penalty of misplaced confidence. The little ball of flesh and fluffy feathers was perfectly useless, so after a day or two, the length of time depending on the tem- perature, it was thrown away. My curiosity concerning the Chickadee being satisfied, and the bird’s tameness making it too easy 47 48 BIRD STUDIES WITH A CAMERA a mark even for a bean-shooter, I entered on a new phase of Chickadee relations. Strangely enough, the killing of the bird seemed, from my point of view, to constitute an introduction to a creature which before I had known only imperfectly, and my acquaintance with the Chickadee may be said to have begun when I picked up the first bird that fell before my aim. However the Chickadee may have regarded my somewhat questionable manner of gaining his friendship, he has since given unmis- takable evidences of his approval of my treatment of his kind. He always replies to my greeting, often coming many yards in answer to my call, and on a number of occasions he has honored me above most men by alghting on my hand. When, in more recent years, the gun which suc- ceeded the bean-shooter was in turn replaced by a camera, I found that the Chickadee’s tameness made him a mark for my later as he had been for my earlier efforts in bird hunting. Now, however, I believe I may speak for him as well as for myself, and say that the results obtained are more satisfac- tory to us both. It was in Central Park, New York city, in February, 1899, that I went on one of my first Chickadee hunts with a camera. Incidentally the locality gave emphasis to the advantages of the camera over any other weapon. Imagine the sur- prise of the park police had I ventured on their pre- cincts with agun on my shoulder! But with a cam- era I could snap away at pleasure without any one’s being the wiser—many of my “snaps,” I confess being attended by exactly this result. At this time, through the efforts of an enthusiastic and patient THE CHICKADEE 49 bird lover, who had improved on the bird-catching legend by using nuts instead of “salt” and by sub- stituting bill for “tail,” three Chickadees in the Ramble had become so remarkably tame that they would often flutter before one’s face and plainly give expression to their desire for food, which they took from one’s hand without the slightest evidence of fear. Sometimes they even remained to pick the nut from a shell while perched on one’s finger, anon 24, Chickadee on ground. casting questioning glances at their host; but more often they preferred a perch where they could give their entire attention to the nut which was held between their feet, and pecked at after the manner of Blue Jays. In spite of the ease with which one could ap- proach these Chickadees, they made difficult marks for the camera. I was armed with a “Henry Clay” 5x7 and a twin-lens camera of the same size, but 5 50 BIRD STUDIES WITH A CAMERA so active were the little creatures that not one of many exposures proved to be perfectly focused. Finally I tried decoying the birds to a bone or bit of bread in the bushes, but somehow they did not 25. Chickadee taking piece of bread. succeed in discovering these baits until they were placed on the ground.» *” Then they responded so quickly that often the bread had disappeared while my head was concealed by the dark-cloth, and fre- quently, while focusing, the birds would alight on the tripod of the camera. I was forced, there- fore, to focus on a stone, and, when ready to make the exposure, lay a bit of bread on or near the focal point, the two pictures given being thus ob- tained. Various experiences with these unusually tame birds finally led to what at first thought would have been considered the wholly unreasonable ambition of photographing one of them in my hand. The camera was therefore erected at a suitable point and THE CHICKADEE 51 focused on the trunk of a tree, the shutter set, and slide drawn. Now to get the bird. None was in the immedi- ate vicinity, but a whistle soon brought a response from some neighboring tree tops, and going beneath them I shortly had called the bird down to a nut in my palm, and with him on my finger started to walk the eighty or more feet to the camera. This, how- ever, was asking too much, and the bird abandoned his moving perch for a bordering row of evergreens, from which one or two more trials brought him within a short distance of the desired spot, and rest- 26. A bird in the hand. ing my arm against the tree trunk and with the other hand on the trigger of the shutter I called again the two plaintive notes. The bird’s faith was still strong. Almost immediately he took the de- 52 BIRD STUDIES WITH A CAMERA sired position, when a click announced the realiza- tion of a bird photographer’s wildest dream. Fortunate is the bird photographer who discov- ers an advantageously situated Chickadee’s nest. Dr. Robert’s charming description in Bird-Lore of his experience with a family of Chickadees stimu- lated my desire to make a camera study of this spe- cies. The first nest found, however, was claimed by a band of roving boys, who in pure wantonness pushed down the stub from which a few days later the young would have issued. A second time I was more fortunate. It was on the morning of May 29, 1899, at Englewood, N. J., that in going through a young second growth I chanced to see a Chickadee, who in arranging her much-worn plumage gave unmistakable evidence of haying recently left her nest. At once I looked about for a partly decayed white birch, a tree espe- cially suited to the Chickadee’s powers and needs. The bark remains tough and leathery long after the interior is crumbling, and having penetrated the outer shell the Chickadee finds no difficulty in exca- vating a chamber within. A few moments’ search revealed a stub so typical as to match exactly the image I held in my mind’s eye, with an opening about four feet from the ground. The interior was too gloomy to enable one to determine its contents, but, returning in half an hour, I tapped the stub lightly, when, as though I had released the spring of a Jack-in-a-box, a Chicka- dee popped out of the opening and into a neighboring tree. I wished her good morning, assured her that THE CHICKADEE 53 my intentions were of the best, and promised to return and secure her portrait at the first oppor- tunity. Four days later I set up my camera before the door to the Chickadee’s dwelling, and, without at- tempting to conceal it, attached thread to the shutter and retreated in the undergrowth to a distance of about twenty-five feet. After having had most discouraging experiences with several birds, who had evidently regarded the camera as a monster of destruction, and had refused to return to their nests as long as the evil eye of the lens was on them, it was consoling to find a bird who had some degree of confidence in human nature as represented by photographic apparatus. It is true that the female—and throughout this description I assume that the bird with much-worn plumage was of this sex—promptly left the stub at my approach; but when I retired to the undergrowth there was no tiresome wait of hours while the bird, flitting from bush to bush, chirped suspiciously, but almost immediately she returned to her home.”” The camera was examined, but clearly not considered dangerous, its tripod sometimes serving as a step to the nest entrance. The click of the shutter, how- ever, when an exposure was made as the bird was about to enter its dwelling, caused some alarm, and she flew back to a neighboring tree, and for some time hopped restlessly from limb to hmb. The male, who had previously kept in the back- ground, now approached, and, as if to soothe his troubled mate, thoughtfully gave her a caterpillar. She welcomed him with a gentle, tremulous flutter- 54 BIRD STUDIES WITH A CAMERA ing of the wings—a motion similar to that made by young birds when begging for food. He, however, made what appeared to be precisely the same move- ments when she perched beside him. It was not long before the female be- came so accustomed to the snap of the shutter that in order to prevent her from entering the nest I was forced to rush out from my hiding place; but at last, apparently becoming desperate, she suc- ceeded in returning to her eggs in spite of my best efforts to prevent her. There now ensued a very interesting change in the bird’s action. It will be remembered that at first she had left the nest on hearing me approach, while a light tap brought her through the opening with startling promptness. But now, evidently realizing that a return to her duties of incubation could be made only at great risk, she determined under no conditions to leave her eggs. In vain I rapped at THE CHICKADEE Iai her door and shook her dwelling to its foundations ; no bird appeared, and not believing it possible that under the circumstances she would remain within the stub, I felt that she must have left without my knowledge, and there- fore retired to await her reappearance. At the end of sev- eral minutes the male, with food in his bill, advanced cautiously, and clinging to the rim of the nest open- ing, hung there a mo- ment and departed minus the food. This was surprising. Could there be young in the nest ? or was the bird, in imitation of the Hornbill, feeding his imprisoned mate? I rapped again, and this time, perhaps taken unawares, the female answered my ques- tion by appearing. On June 3d a family arrived in the Chickadee villa, and both birds were found actively engaged in administering to its wants. As areturn for the inconvenience to which they had been subjected, a perch was erected by way of a step at their door. The female was appreciative and 28. Chickadee at nest hole. 56 BIRD STUDIES WITH A CAMERA at once availed herself of this means of entering her home. The male, however, as before, was more wary. He had braved the camera to bring food to his mate, but his offspring had apparently not so strong a claim upon him. He would fly off in search of food and shortly return with a caterpillar, then perch quietly for several minutes a few yards from the nest, when, repelled by the camera and attracted by the food in his bill, he yielded to temptation, de- voured the caterpillar, vigorously wiped his bill, at once started to forage for more food, and returned with it only to repeat his previous performance. Occasionally he uttered a low whistle, addressed presumably to the female, and at times a chickadee- dee-dee, which I interpreted as a protest to me, and both notes were also uttered by the female. The latter took so kindly to the doorstep that it was determined to give her a door, and to this end a leaf was pinned over the entrance to her home in such a manner that it swung to and fro, like the latch toa keyhole. This clearly did not meet with her approval, and at first she seemed puzzled to ac- count for the apparent disappearance of the nest opening. But in less than a minute she solved the mystery, pushed the leaf to one side, and disappeared within. Returning to the nest on June 12th, nothing was to be seen of either parent, and I feared that they or their offspring had fallen victims to the countless dangers which beset nesting birds and their young. Looking about for some clew to their fate, I found on the ground, near the nest stub, the worn tail-feath- ers of the female bird. The molting season had not THE CHICKADEE 57 yet arrived, nor would she have shed all these feath- ers at the same moment. |There could therefore be only one interpretation of ‘their presence. Some foe —probably a Sharp-shinned or Cooper’s Hawk, since the predaceous mammals for the most part hunt at night, when the Chickadee would be snugly sleep- ing in her nest—had made a dash and grasped her by the tail, which she had sacrificed in escaping. A moment later the theory was supported by the ap- pearance of a subdued-looking Chickadee, sans tail, and I congratulated her on her fortunate exchange of life for a member which of late had not been very decorative, and of which, in any event, Nature would have soon deprived her. The young proved to be nearly ready to fly, and, carefully removing the front of their log cabin, a sight was disclosed such as mortal probably never beheld before and Chickadee but rarely. Six black-and-white heads were raised and six yellow-lined mouths opened in expressive appeal for food. But this was not all; there was another layer of Chickadees below—how many it was impossible to say without disentangling a wad of birds so com- pact that the outlines of no one bird could be dis- tinguished. A piazza, as it were, was built at the Chickadees’ threshold in the shape of a perch of proper size, and beneath, as a life net, was spread a piece of mosquito bar. Then I proceeded to indi- vidualize the ball of feathers; one, two, three, to seven were counted without undue surprise, but when an eighth and ninth were added, I marveled at the energy which had supplied so many mouths with food, and at the same time wondered how many 58 BIRD STUDIES WITH A CAMERA caterpillars had been devoured by this one family of birds. Not less remarkable than the number of young— and no book that I have consulted records so large a brood—was their condition. Not only did they all appear lusty, but they seemed to be about equally developed, the slight difference in strength and size which existed being easily attributable to a differ- 29, A Chickadee family. ence in age, some interval doubtless having elapsed between the hatching of the first and last egg. This fact would have been of interest had the birds inhabited an open nest, or a nest large enough for them all to have had an equal opportunity to receive food; but where only two thirds of their number could be seen from above at once, and where avery little neglect would have resulted fatally, it seems remarkable that one or more, failing to receive his share of food, had not been weakened in conse- THE CHICKADEE 59 quence and crushed to death by more fortunate members of the brood. Nor was their physical con- dition the only surprising thing about the members of this Chickadee family: each individual was as clean as though he had been reared in a nest alone, and an examination of the nest showed that it would have been passed as perfect by the most scrupulous sanitary inspector. It was composed of firmly pad- ded rabbit’s fur, and, except for the sheaths worn 30. A Chickadee family. off the growing feathers of the young birds, was absolutely clean. Later, I observed that the excreta of the young were inclosed in membranous sacs, which enabled the parents to readily remove them from the nest. The last bird having been placed in the net, I at- tempted to pose them in a row on the perch before their door. The task reminded me of almost forgot- 60 BIRD STUDIES WITH A CAMERA ten efforts at building card houses, which, when nearly completed, would be brought to ruin by an ill-placed card. How many times each Chickadee tumbled or fluttered from his perch I can not say. The soft, elastic net, spread beneath them, preserved them from injury, and bird after bird was returned to his place so little worse for his fall that he was quite ready to try it again. Finally, eight birds were induced to take the positions assigned them ; then, in assisting the ninth to his allotted place, the balance of a bird on either side would be disturbed, and down into the net they would go. These difficulties, however, could be overcome, but not so the failure of the light at the critical time, making it necessary to expose with a wide open lens at the loss of a depth of focus. The picture presented, therefore, does not do the subject justice. Nor can it tell of the pleasure with which each fledgeling for the first time stretched its wings and legs to their full extent, and preened its plumage with before unknown freedom. At the same time they uttered a satisfied little dee-dee-dee, in quaint imitation of their elders. When I whistled their well-known phe-be note, they were at once on the alert, and evidently expected to be fed. The birds were within two or three days of leav- ing the nest, and, the sitting over, the problem came of returning the flock to a cavity barely two inches in diameter, the bottom of which was almost filled by one bird. I at once confess a failure to restore anything like the condition in which they were found, and THE CHICKADEE 61 when the front of their dwelling was replaced, Chickadees were overflowing at the door. If their healthfulness had not belied the thought, I should have supposed it impossible for them to exist in such close quarters. A few days later their home was deserted, and, as no other Chickadees were known to nest in the vicinity, I imagine them to compose a troop of birds which is sometimes found in the neighborhood, THE LEAST BITTERN AND SOME OTHER REED INHABITANTS A Y experience with the Least Bittern { leaves the eerie little creature a ( half-solved mystery, and I think of | | it less as a bird than as a survivor | of a former geological period, when birds still showed traits of their eee ial not distant reptilian ancestors. The Bittern’s home is in fresh-water, cat-tail marshes, and he wanders at will through the thickly set forest of reeds without of necessity putting foot to the water below or flapping wing in the air above. His peculiar mode of progression constitutes one of his chief characteristics. The reeds in which he lives generally grow in several feet of water, far too deep, therefore, to permit of his wading; while his secretive disposition makes him averse to appearing in the open, except after nightfall. It is impossible to fly through the cat-tails, and so the bird walks and even runs through them, stepping from stem to stem with surprising agility. I had heard of this habit, but the description conveyed as little idea of the bird’s appearance as it is feared this one will, and when for the first time a Least Bittern was seen striding off through the reeds about three feet above the water, the performance was so entirely unlike 62 THE LEAST BITTERN 63 anything I had ever seen a bird do before, I mar- veled that his acrobatic powers had not made him famous. The feathered gymnast’s slender body—or per- haps one should say neck, for the bird is chiefly neck and head—seemed to be mounted on long stilts, with the aid of which he waded rapidly through the water, his head shooting in and out at each stride. The Least Bittern’s notes appear to be less known than his habits. Nuttall, that exceptionally keen- eared bird student, was familiar with them, but most writers have restricted themselves to the state- ment that, when flushed, the bird utters alow qua, while some have even said he was voiceless. I should not be in the least surprised to learn that this uncanny inhabitant of the reeds had a call fully as remarkable as the vocal performance of his large relative, the American Bittern, but thus far in my slight acquaintance with him he has been heard to utter only four notes: A soft, low coo, slowly repeated five or six times, and which is probably the love song of the male; an explosive alarm note, quoh ; a hissing hah, with which the bird threatens a disturber of its nest; and a low ftut-tut- tut, apparently a protest against the same kind of intrusion. It was the markedly dovelike coo which first in- troduced me to this species. With William Brew- ster I was at the Fresh Pond marshes, listening for the repetition of some strange calls which had ex- cited the curiosity of Cambridge ornithologists, and which proved to belong to a Florida Gallinule,* * See Brewster, Auk, vol. viii, 1891, p. 1. 64 BIRD STUDIES WITH A CAMERA when we heard the soft notes of a Least Bittern, who soon rose from the marsh near by. A few days 31. Least Bittern’s nesting site, showing reeds bent over nest. One of four eggs can be seen. later the Bittern was found in full song—if the coo be its song—in the marshes of Presque Isle in Erie THE LEAST BITTERN 65 Bay ; but it must be confessed that a desire to secure specimens of this, to me, strange bird left no oppor- tunity to study its habits, and the species was not again observed until June, 1898, in the northern part of Cayuga County, New York. Here, under the guidance of an observing local ornithologist, Mr. E. G. Tabor, an encounter was had with a Least Bittern which made a unique page in my experience as a bird student. It was on the border of Otter Lake, where the Least Bitterns nest in small numbers in low bushes, or a mass of drift, or more often in the fringe of cat- tails. The trail of a boat through the reeds and empty nests, which before had held from three to five eggs, marked the ill-directed work of the boy odlogists whose misspent zeal has resulted in such a vast accumulation of eggshells and such an ab- sence of information about the birds that laid them. A visit to a more distant part of the lake, where even thus early in the year the cat-tails were five feet above water of over half that depth, saved the day, as far as Least Bitterns were concerned. Pad- dling close to the reeds, a practiced eye could dis- tinguish the site of a Bittern’s nest, when the nest itself was invisible, by the bowed tips of the reeds which the bird invariably bends over it.* The object of this habit is perhaps to aid in concealing the eggs from an enemy passing overhead—a Crow, for exam- ple—an attack by boat evidently not being taken into consideration. Certainly our appearance was in the nature of a surprise to a pair of birds who had just completed their platformlike nest and were appar- 6 32. Least Bittern’s nest; rceds parted to show eggs. ently discussing future steps in their domestic affairs. As we approached, the female, who even before the eggs are laid seems to have the home love more strongly developed than the male, bravely stuck to THE LEAST BITTERN 67 her post, while the male marched off through the reeds in the manner which has been described as so remarkable. When he paused, with either foot grasping reeds several inches apart or clung to a single stalk with both feet, he re- sembled a gigan- tic, tailless Marsh Wren. The actions of the female were in- teresting in the extreme. Her first move was an at- tempt at conceal- ment through pro- tective mimicry—a rare device among birds. Stretching her neck to the utmost, she pointed her bill to the ze- nith, the brownish marks on the feath- ers of the throat be- came lines which, separated by the white spaces be- tween them, might easily have passed for dried reeds, and the bird’s statuelike pose, when almost within reach, evinced her belief in her own invisi- ulity.33* The pose recalled Hudson’s experience with a 53. Least Bittern on nest mimicking its sur- roundings. 68 BIRD STUDIES WITH A CAMERA wounded Least Bittern (Ardetta involucris, a near relative of our bird) in the marshes of La Plata, where a bird at his feet, in the same position as the one before me, was discovered only after careful search, and which, to the naturalist’s amazement, slowly revolved as he walked around it, with the presumable object of keeping its pro- tectively colored breast turned toward him. My bird, how- ever, Was among fresh reeds, and while one can not doubt the effec- tiveness of its at- titude and color, when seen among dead reeds or grasses, neither were of value among its green 34. Least Bittern on nest mimicking its sur- surroundings. eee With the light on the wrong side and the reeds swaying violently in the wind, we essayed to picture the bird, and the best of several attempts made under these adverse conditions are here given. Covering my hand with my cap I held it toward her, when, convinced that her little trick had failed, she adopted new tactics, and struck at me with force and rapidity, which made me thankful that my hand THE LEAST BITTERN 69 was protected. Her bright yellow eyes glared with the intensity of a snake’s, and her reptilelike appear- ance was increased by the length and slenderness of her head and neck. Her courage was admirable ; she not only displayed no fear, but was actually aggressive, and with a hissing hah struck viciously at my hand each time it was placed near the nest. As I quickly retreated on each occasion, and at length made no further move toward her, she de- cided to withdraw, perhaps to join her cautious mate, who from the reeds had been uttering a warning tut- tut-tut at intervals. Very slowly and watchfully she left the nest, and when she had advanced a few feet through the reeds I again ventured to touch her platform home, putting my hand, however, under it; but the motion instantly attracted her attention, and, darting back to her post, she was on guard ina moment. Then I left her, retiring from the field fairly vanquished in my first hand-to-bill encounter with a wild bird. I hope she laid a full complement of five eggs and from them reared five birds worthy representatives of their mother. A desire to renew my acquaintance with—or per- haps I should say advances toward—this unbird- like feathered biped, and to meet it under conditions more favorable for the camera hunter, brought me the following year (June 17, 1899), to the Montezuma marshes at the head of Cayuga Lake. Here are endless forests of cat-tails in which dwell not only Bitterns, Long-billed Marsh Wrens, and Red-winged Blackbirds, but also numbers of Pied-billed Grebes and Florida Gallinules. aenee 70 BIRD STUDIES WITH A CAMERA There is a mystery about a marsh akin to that which impresses one in a primeval forest. The pos- sibilities of both seem limitless. One hears so much and sees so little. Birds calling from a distance of only a few yards may remain long unidentified. A rustling in the reeds arouses vague expectations. The notes of marsh-inhabiting birds are in keep- ing with the character of their haunts. They are distinctly wild and strange, and often thrilling. The Rails, for example, all have singular, loud, startling calls. The American Bittern is a famous marsh songster, but although several of his common names are based on his calls, it is only recently that he has actually been seen uttering them. The Gallinule re- sembles the hen in the character, volume, and variety of its notes, and to it and not the Clapper Rail should be given the name “Marsh Hen.” Indeed, its European relative, from which it can scarcely be distinguished, is known as the Moor Hen or Water Hen. But of all this marsh music none to my ear is more singular than the call of the Pied-billed Grebe. It is mentioned in few books, and has won the bird no such fame as the Loon’s maniacal laugh- ter has brought him, though as a vocalist the Grebe fairly rivals his large cousin. Like most bird calls it is indescribable, but perhaps sufficient idea of its character may be given to lead to its identification when heard. It is very loud and sonorous, with a cuckoolike quality, and may be written cow-cow- COW-COW-COW-COw-Ccow-cow-cow-uh, cow-uh, cow-uh, cow-uh, These notes vary in number, and are some- times followed by prolonged wailing cows or ohs THE LEAST BITTERN val almost human in their expressiveness of pain, fear, and anguish. This is the love song of the male, and when he has won a mate she joins him in singing, uttering, as he calls, a rapid ewk-cuk-cuk, followed by a slower ugh, ugh, ugh, ugh. The Gallinules were cackling in the reeds, where a nest with three hatching eggs was found, but not a bird was seen. Red-winged Blackbirds were chat- tering with excitement as they guided the first wing strokes of their young, who perched on the reeds begged eloquently for food rather than for lessons in flying.® In a small island of cat-tails a pair of Grebes was calling, and after the most careful stalking my com- panion saw the female respond to the voice of her mate. 72 BIRD STUDIES WITH A CAMERA It was in this island—if a patch of cat-tails grow- ing in three feet of water can be called an island— that we found the first two of numerous Least Bit- terns’ nests, and here our camera studies were made. These nests were typical in form and site; one con- tained five and the other four*® eggs, from which the birds had apparently departed as we pushed our boat toward them. Less than twenty minutes later we again passed these nests and found, to our surprise, that in one all four, and in the other two eggs had been punc- tured, as if by an awl. Here was a mystery which my companion, who was examining the second nest while I was studying the first, quickly solved by seeing a Long-billed Marsh Wren actually make an attack on the remaining three eggs, and a little later a bird of the same species—perhaps the same individual, since the Bitterns’ nests were not more than twenty yards apart—visited the first nest to complete its work on the five already ruined eggs. Our attempt to photograph the energetic little marauder failed, nor did we succeed in learning the real cause of its remarkable destructiveness. How- ever, the fact that in one nest alone it drove its needlelike bill into all five eggs without pausing to feast on their contents, would imply that it was not prompted by hunger, and, much against our will, we were forced to attribute the bird’s actions to pure viciousness; though, it is true, there may have been another side to the story, in which the Bittern was the culprit. The owners of the four eggs did not return while THE LEAST BITTERN 13 36. Least Bittern eating her eggs. we were present, and the following day we found their nest empty—a mute protest against fate. The female of the second nest discovered, in which only two of the five eggs had been injured, proved to be a bird of character. T4 BIRD STUDIES WITH A CAMERA While we waited in our boats at a distance of fifteen feet, and with cameras erected on tripods 37. Least Bittern on nest. at a third of the distance, she came walking through the reeds uttering occasionally an explosive quoh / THE LEAST BITTERN 45 After circling about us several times she climbed to her nest, and at once proceeded to investigate the condition of its contents. Soon she gave evidence of the possession of both a philosophic and economic disposition, not to mention other housewifely quali- ties, notably cleanliness. Philosophy she exhibited by making the best of things as she found them; economy by carefully eating*® the two broken eggs, which a more thoughtless bird would have deserted or quickly discarded; and cleanliness by carefully dropping over the edge of the nest the shells remain- ing from her peculiar feast, and following them by bits of nest hning which had been soiled by portions of the egg. This task accomplished to her satisfac- tion, she gave further evidence of the possession of a well-ordered mind by descending to the water, washing her bill, drinking, and then returning to her remaining three eggs, on which she settled herself *7 as complacently as though she had met with no loss, and there we left her in well-deserved privacy. TWO HERONS VN this age of death and destruction | to all living creatures, which, be- cause of their size or edible quali- ties, the so-called sportsman is proud to exhibit as evidence of his skill afield, it is remarkable that there should exist within twenty odd miles of New York’s City Hall a colony of Herons which would do credit to the most remote swamp of Florida. Three factors have combined to render this rook- ery possible: first, its isolation; second, the habits of its occupants; and third, the protection which is afforded it by the owner of the land on which it is situated. Of these, the first is by far the most im- portant, and I may be pardoned, therefore, if I do not betray the birds’ secret; for, much as I desire to encourage American industries, J must on this occa- sion withhold information of undoubted value to the feather trade. The birds’ habits contribute toward their preser- vation, because they are largely nocturnal, “ Night” being the specific name applied by the text-books to this particular kind of Heron; but to those who know him in nature, he is generally spoken of as “Quawk,” this being an excellent rendering of his common call. 76 TWO HERONS ny The Night Heron or Quawk belongs among the birds for whom the setting sun marks the beginning of a new day—a fact which protects him from man and permits his existence in numbers where others of his family are rarely seen. Doubtless many of the residents of Heronville know their feathered neighbors only as a voice from the night, which comes to them when the birds, in passing over, utter their loud and startling call. Finally, to the protecting influences of a love for seclusion and darkness must be added the unusual position assumed by the proprietor of the land, who will not permit any one to kill the birds, and, stranger still, does not kill them himself! Thus it happens that any day in May or June, the months during which the Herons are at home, one may leave the crowded streets of New York and within an hour or so enter an equally crowded but quite different kind of town. If after leaving the train you secure the same guide it was my good fortune to have, your way will lead over shaded roads, pleasant fields, and quiet woodland paths, and, if the sun is well up in the trees, you may enter the outskirts of the rookery and be wholly unaware, unless you approach from the leeward, that between two and three thousand Herons are within a few hundred yards of you. One may gain a far better idea of Heron life, however, by visiting the rookery while the foliage is still glistening with dew. Then, from a distance, a chorus of croaks may be heard from the young birds as they receive what, in effect, is their supper. Old birds are still returning from fishing trips, and q8 BIRD STUDIES WITH A CAMERA the froglike monotone of the young is broken by the sudden quawks of their parents. The rookery is in a low part of the woods which evidently is flooded early in the year, a fact which may have influenced the Herons in their selection of the locality as a nesting site. At the time of our visit the swamp maples, in which the nests are placed, were densely undergrown with ferns, and as we approached the whitened vegetation, which clearly marked the limits of the rookery, a number of Herons with squawks of alarm left the vicinity of their nests, and soon the rookery was in an up- roar. The common quawk note was often heard, but many of the calls were distinctly galline in character and conveyed the impression that we had invaded a henroost. The trees in which the nests were placed are very tall and slender, mere poles some of them, with a single nest where the branches fork; while those more heavily limbed had four, five,** and even six of the platforms of sticks, which with Herons serve as nests, but in only a single instance was one nest placed directly below another. A conservative count yielded a total of five hundred and twenty-five nests, all within a circle about one hundred yards in diam- eter, nearly every suitable tree holding one or more, the lowest being about thirty feet from the ground, the highest at least eighty feet above it. While the limy deposits and partially digested fish dropped by the birds seemed not to affect the growth of the lower vegetation, it had a marked influence on certain of the swamp maples, the devel- opment of the trees which held a number of nests TWO HERONS 79 being so retarded that, although it was June 13th, they were as yet only in blossom.* The compara- tive absence of foliage permitted one to have a far better view of what was going on above than if the trees had been thickly leaved, and on entering 88.

It was with a delightful sense of companionship with the birds that I observed them going and com- ing, feeding their young, or resting after the night’s TWO HERONS 83 labors, wholly undisturbed by my presence. Almost I seemed to be a guest of the rookery, and I longed for power to interpret the notes and actions of the birds so abundant about me. So I should hke to have passed the day with them, becoming for the time being a Heron myself; 42, Young Night Herons leaving nest.

The rookery proved to be a difficult subject. No single view would convey an adequate idea of its appearance, and I therefore selected representative tree tops and photographed their nests and young birds. A visit to a neighboring pond resulted in 84 BIRD STUDIES WITH A CAMERA securing, with the aid of a telephoto, a picture® of two adult birds feeding well out of gunshot, and with the assistance of climbers I reached the upper branches of a tree some seventy feet in height con- taining five nests whose contents ranged from eggs to nearly grown young.

Young Night Herons on branches lative. near nest, seventy feet from the As the sun crept up- ies ward and the last fishers returned, the calls of both old and young birds were heard less and less often, and by ten o’clock night had fallen on the rookery and the birds were all resting quietly. Four o’clock in the afternoon was evidently early morning, and at this hour the birds TWO HERONS 8B first began to leave the rookery for their fishing grounds. Some went toward the north, others to the south, east or west; each bird no doubt having clearly in mind some favorite shore, perhaps a dozen miles away, where he before had had good luck a-fishing; and of all the varied phases of rookery life the thought of this regular nightly expedition of hundreds of winged fishers, is to me the most at- tractive. Our largest Heron as well as our largest bird is the Great Blue. “Crane” he is popularly called; but, aside from other differences, the bird’s habit of folding its neck back on its shoulders, when on the wing, will distinguish it from true Cranes, who fly with neck extended to the utmost. The Great Blue Heron is not edible, but its size makes it a desirable prize to most gunners and it is considered an especially fit mark for a rifle. The temptation is strong to condemn as an outlaw the man who kills one of these noble birds for what he terms sport, or perhaps for the purpose of what he would call having it “set up.” He, however, is act- ing according to his light, which is quite as bright as that which shines for most of his neighbors. The Heron is exceedingly wild, and its capture is elo- quent evidence of the hunter’s prowess, while his desire to have its stuffed skin adorn his home is, from his point of view, positively commendable. That the bird is infinitely more valuable alive than dead, that its presence adds an element to the land- scape more pleasing to some than could be imparted by any work of man, and that in depriving others 86 BIRD STUDIES WITH A CAMERA of the privilege of observing its singularly stately grace of pose and motion he is selfish beyond expres- sion, does not even vaguely occur to this so-called “ sportsman,’ who belongs in the class to whom a majestic cliff is a quarry, a noble tree, lumber. Until he has been educated to properly value the beauties of Nature, or at least realize the rights of others in them, he must be restrained by law, to the force of which even he is not blind. Only the Great Blue Heron’s extreme wariness and habit of frequenting shores and marshes where it can command an extended view of its surround- ings has preserved it from extinction; but when nesting it is compelled to visit woodlands where its human enemies have better opportunities to ap- proach it, and its only chance for safety during the breeding season is to select a retreat remote from the home of man. For this reason Great Blue Heron rookeries are exceedingly uncommon in more settled parts of the bird’s range, and north of Florida I have seen their nests in only one locality. It was the week after my visit to the Night Herons that, in northern Cayuga County, New York, I was led by a local ornithologist through one of the heaviest pieces of timber I have ever seen north of a primeval tropical forest, in search of a Great Blue Heron rookery which he knew to exist, and only my confidence in his woodsmanship gave me courage to follow him over fallen trees and through the season’s dense undergrowth, from which our passage raised such a host of mosquitoes that every step was a battle. If the vicious little insects had lived only to protect the Herons, they could not TWO HERONS 87 have disputed our progress more valiantly, and on reaching the birds’ stronghold, where the compara- tive absence of undergrowth deprived our winged foes of shelter, I congratulated myself on what, for the moment, seemed to be no insignificant feat. The eleven nests which my guide had seen on a previous occasion were found occupying ‘their for- mer positions, at least one hundred feet from the ground in dead trees, one of which held five of the eleven. During the many years which the birds have nested in the place their number has not varied, and one wonders what becomes of the from thirty to forty young who doubtless each year leave the parental trees. No other Herons of this species are known to nest in the vicinity, and it is not prob- able that the progeny of each year would seek a nesting site in some far distant rookery; conse- quently, as an alternative explanation, we can only suppose that the yearly product of the rookery bal- ances its losses by death. The young birds were now nearly half grown, but, unlike the Night Herons, they did not venture outside their nests, from which they uttered harsh croaks in evident supplication to their parents for food. The sight of the trees in which the nests were placed effectually controlled whatever ambi- tions I had entertained toward camera studies at short range, and I contented myself by making tele- photos from the ground, in one of which an adult bird and two nests, each with a young bird appear- ing above its edge, may be seen.“ Time was lacking in which to observe these birds, and the value of my visit to their retreat is not to 88 BIRD STUDIES WITH A CAMERA be expressed in words. The wildness of their home seemed in perfect accord with their nature, and their 44, Looking upward from ground to nests and young and adult bird of Great Blue Heron at a height of over one hundred feet. Telephoto. apparent safety from intrusion brought a sense of satisfaction which colors my memory of the whole experience. WHERE SWALLOWS ROOST ONTRIBUTING little to the ma- terial wealth of the nation, the Hackensack marshes of north- ern New Jersey are usually re- garded as “waste land.” By the farmer they are termed “salt medders,” and their waving grasses are of value to him only as “bedding” for cattle. In winter the muskrat hunter reaps a har- vest of pelts there. The down of the “cat-tails” is gathered for cushion stuffing, and the bladed leaves for chair bottoms. To the gunner they are the resort of Ducks, Snipe, Rail, and Reedbirds, which each year visit them in decreasing numbers; while to the thousands who daily pass them on the encir- cling railroads they are barren and uninteresting. But if beauty is a sufficient cause for being, then these marshes may claim a right to existence. In preglacial times this region was probably for- ested, but now the forest is buried beneath the drift of the glacier which deposited fragments of Palisade and Orange Mountain trap rock on Staten Island. During the depression of the land which occurred as the ice gradually receded, the waters of the sea doubtless passed up here and the meadow was a larger “ Newark Bay.” Then commenced their slow 89 MGs ee 45, Hackensack marshes in August. WHERE SWALLOWS ROOST 91 filling up by the silt brought down by the Hacken- sack River. The river has preserved a right of way, but the bay has given place to a sea of reeds and grasses. Ona bright August morning I mount a spur of trap rock which reaches out from the western base of the Palisades, and from this elevation have an uninterrupted view over the meadows. The cool, in- vigorating air foretells the approach of autumn; it is brilliantly clear. The Orange hills stand out with the distinctness of Western mountains. The sun is at my back, and the light shows the meadows to the best advantage. At this distance I get the effect of only the masses of color; tracts of yellow- ish green meadow grass tinged with copper, and in places thickly sprinkled with the white flowers of the water hemlock and water parsnip; streaks of light green wild rice, and sharply defined areas of dark green cat-tail flags. The grass grows on the drier land, the wild rice in the small sloughs and creeks which are bordered by the flags. In the spring the wind blows the pollen from the cat-tail blossoms, and a shifting greenish vapor floats over the marsh; in the autumn a heavy westerly wind raises the seed-bearing down high in the air, carries it over the Palisades, across the Hudson, and it de- scends like a fall of fleecy snow on wondering New York. The marsh is a vast arena inclosed by the Pali- sades and Passaic hills; it isa great plain, with blue stretches of the winding river appearing here and there, and the haystacks are the huts of aborigines. I half close my eyes, and it is a copper-yellow sea. 92, BIRD STUDIES WITH A CAMERA The grasses roll in undulating waves, capped by a white crest of parsnip and hemlock blossoms; the dark irregular patches of flags are the shadows of clouds, the light streaks of wild rice are shoals, a hovering Marsh Hawk isa Gull. A stately white- winged schooner“ comes up the river; her hull is hidden by the meadow grasses ; she is sailing through the sea of my fancy. This is an impressionist’s view of the meadows. Now let us leave our rocky lookout and examine them more in detail. The meadow we are leaving is a meadow of all summer; the one we are approach- ing is a meadow clad in all the glory of its August flowers. One might think Nature was holding a flower show here, so gorgeous is the display. The railway track at the edge of the marsh is apparently an endless aisle bordered by a rich exhibit of flowers. Clusters of thoroughwort and purple loose-strife grow so abundantly they give color to the fore- ground, through which wild sunflowers make streaks of gold. There are solid beds of purple asters on the drier land, and delicate snow-white saggitarias in the sloughs. Jewel flowers sparkle through the flags, and convolvulus hangs from the reeds, its own foliage scarce showing, or, growing with the fra- grant climbing hempweed, it forms banks of dense vegetation. The scarlet lobelia darts upward like a tongue of flame, startling in its intense brilliancy. There are burnet, vervain, gerardia, and running groundnut. But it is the marsh*® mallow which, more than any other flower, gives beauty to the meadow. It grows here with wasteful luxuriance, and the dark masses of flags serve as a frame for WHERE SWALLOWS ROOST 93 this floral picture. Out in the marsh it grows in equal profusion; the meadow is hung with small pink lanterns, as if for a féfe. A single flower of the marsh mallow commands the attention of the most unobservant, and when growing in abundance it excites enthusiastic admiration. 46. Marsh mallows. Nor is the animal life of the marsh less interest- ing than its flora. Meadow mice nest beneath the haycocks. Were it not for the minks and Hawks which prey on them, they might become a scourge throughout the surrounding country. Muskrats are 94 BIRD STUDIES WITH A CAMERA living in peaceful security in their snug summer homes, hollowed from the banks of the streams. They are the true villagers here, and pass the win- ter in icy huts, like Eskimos. Out in the grasses Short-eared Owls are hiding. Their day begins when the sun disappears behind the Orange hills; then one may hear the “quawk” of the Night Heron. Red-winged Black- | ame birds nest here, and in the autumn they , gather in great | iii | tee flocks and feed on VA the wild rice. Long-billed Marsh Wrens — small, nervous, ex- citable bits of feathered life—are abundant in the flags, and to them they attach their large woven nests. Except for a harsh, scolding note they are silent now, but earlier in the year the marsh is mu- sical with their rip- pling songs. The fervor of the love season over- comes their fondness for the dark recesses of the flags, and, singing, they rise into the air as if driven 47, Wild rice. WHERE SWALLOWS ROOST 95 upward by the mine of melody which explodes with- in them. Swamp Sparrows are common, and their clear trill is one of the few August songs. Bobolinks, traveling in disguise and under the assumed name of “ Reedbird,” pause here to feed on the ripening wild rice.” Some of them have not yet completed their change of costume and appear in a spotted suit of black and yellow. Occasionally one hears a sup- pressed burst of the “ mad music” of June, but their common note is a metallic chink. At night this note is heard from high in the air, as the birds con- tinue their journey to the cultivated rice fields of South Carolina and Georgia, there to remain until September or October, when they leave for their winter home south of the Amazon. The Sora Rails, beloved of sportsmen and epi- cures, are also attracted to the marshes by the wild rice. On their arrival in early August they are in- deed “as thin as a rail,’ but an abundance of food soon rounds their bodies into comparative plump- ness. The Ist of September is a black day in their calendar. Then they are outlawed, a price is set on their bodies, and at high tide each day during this sad month one sees numerous puffs of smoke arise from the tall grasses and dull reports come boom- ing over the marsh with fateful frequency. But the characteristic birds of the marshes at this season are Swallows. They outnumber many times all the rest of the marsh birds together—in fact, are present in such myriads that their gatherings are one of the most interesting and impressive phenom- ena of the bird life of this region. 96 BIRD STUDIES WITH A CAMERA Five species are represented. Named in the or- der of their abundance they are the Tree, Bank, Barn, Eave, and Rough-winged Swallows. The last are comparatively rare, while the Tree Swallows are so in excess of all the species named that the follow- ing remarks relate largely to them alone. Although Tree or White-breasted Swallows nest locally throughout North America, from the table- land of Mexico to Labrador and Alaska, there are but few instances of their breeding in the lower Hudson River valley, where they appear only as migrants or transient visitants. They arrive from the south early in April, and their northward migra- tion is not concluded until about June Ist. During June they are rarely seen, but between the 1st and the 5th of July they begin their journey to their winter homes—a movement which inaugurates the fall migration. This stage of their journey takes them only to certain marshes, which become stations on their line of travel where countless numbers of their kind, impelled by the flocking impulse, gather to roost in the reeds. Their numbers increase steadily through July and August, the maximum of abun- dance being reached about September Ist; then they gradually become less numerous, and by October 10th comparatively few remain, though if the weather be favorable, they may be observed daily until late in the month. Throughout this period—from July to October— the marsh is used only as a dormitory, the reeds evi- dently offering suitable perches to these weak-footed birds, who in the morning radiate throughout the sur- WHERE SWALLOWS ROOST 97 rounding country and in the evening return to the marsh to sleep. In the evening they fly low, and the altitude and time of their flight make them con- spicuous. In the morning they fly high, as though bound to some distant feeding ground, and at so early an hour that they usually escape observation. The evening flight, therefore, is generally considered 48. “ Bird notes »— Tree Swallows. as truly migratory, when, in fact, the same birds doubtless pass over a given locality night after night, perhaps for weeks, in returning to their roosts in the marshes. These evening flights begin about two hours and a half before sunset, when the birds, after resting during the late forenoon and early afternoon, usu- ally on some telegraph wire,** begin to wheel and 8 98 BIRD STUDIES WITH A CAMERA circle over the fields in pursuit of their evening meal, when one might imagine they were resident birds, but observation will show that the general trend of their movement is toward the roost. This continues for an hour to an hour and a half, a cloudy evening hastening their actions, when their flight becomes more direct. Few birds pause to feed, but hurry on to the roosting places, and as the light fades the last birds rush through the gloom with arrowy speed and directness. The birds pass in straggling flocks, and periods of abundance are suc- ceeded by intervals of scarcity, as though the indi- viduals which had been associated during the day were journeying home together. Thus the Swallow’s evening flight may be ob- served throughout the region surrounding the marshes ; even in New York city they may be seen feeding above the houses, and after sunset flocks of swift-flying birds are often confused by the tele- graph wires, which, however, their dexterity of wing permits them to pass without serious harm. In the marshes the first birds are seen about two hours before sunset. Many follow the course of the river, and if one be at its border splash after splash is heard as the birds dip lightly into the water, fol- lowed by soft fluffs as arising from the stream they shake their plumage. Soon the air is filled with Swallows, all streaming toward the roost with in- creasing swiftness. Many birds, however, as though waiting for some tardy comrades, rest by the way, perching on tele- graph wires should they cross the marsh, or when these are wanting, on the tips of the reeds. They WHERE SWALLOWS ROOST 99 invariably face the wind, and when it is from the west the last rays of the sun striking their white breasts make them appear like snowy flowers crown- ing the reeds. Suddenly, with a rush, they whirl onward to the roost. Thus far the exact location of this roost has de- fied my search. I have, however, roughly defined the bounds of that section of the marsh in which it is placed by observation stands at which the Swal- lows flew north and south respectively, and some- where between the two I still hope to discover the Swallows’ sleeping haunts. The following description of their departure from the marshes in the morning is abstracted from my journal, under date of August 15, 1886: “ A cool, clear morning, with a light northwesterly wind. I reached the marshes shortly before five o’clock, when they appeared to be deserted, not a Swallow being in sight. At two minutes of five the first birds were observed, then flock after flock they came until at five the air was filled with hurrying forms, flying at varying altitudes toward the north, “Suddenly, from the meadows near me there arose a vast cloud of Swallows, doubtless birds which had come from farther south in the marsh before my arrival. Steadily they mounted upward, until having attained a height where with a strong glass they appeared faint dots against the sky, they slowly winged their way northward. “All the time the meadows were alive with birds feeding in every direction; gradually they passed to the north, when another huge flock arose from the 100 BIRD STUDIES WITH A CAMERA marsh, and after gaining an immense height disap- peared, this time toward the east. “As the sun rose over the Palisades few birds were on the wing, but great flocks were perched in the reeds on the banks of the creek, and as in my canoe I drifted slowly up to them, they seemed unmindful of my pres- ence, when, as though at a signal, they arose as one bird, and after hov- ering lightly overhead returned to the reeds. “The tide was low, and along the shore sev- eral Sora Rail were feed- ing, and, as carried by the tide I floated noise- lessly by, they paused in their search for food, and with tails upraised re- garded me with evident astonishment. A mink approached the shores of a small inflowing stream, hesitated, then plunged in, crossed, and disap- peared in the tall grasses on the opposite side. The air was vocal with the calls of Red-winged Black- birds, the chink of Bobolinks, and the rattle of Swamp Sparrows. “On a reed-grown point below was another great army of Swallows. With surprising regularity a 49. Tree Swallows in tree. WHERE SWALLOWS ROOST 101 detachment left it every fifteen minutes; thus, birds left at 6, 6.15, 6.30, and 6.45, when the reeds were deserted. The departing birds did not arise alone, but the entire flock arose at once, then divided into two flocks, one of which flew northward while the other returned to the reeds. Many of the departing birds alighted on the reeds farther up the creek; their numbers constantly received additions from the ranks of passing birds, and thus new flocks were formed. “ At eight o’clock the last Swallows had left the reeds in my vicinity, but birds were constantly pass- ing toward the north, and this straggling flight con- tinued until nine o’clock, when again the marshes appeared deserted.” Subsequent observations have been made largely from a road crossing the marsh, the telegraph and electric-light wires which border it being the resting place of vast numbers of Swallows, both at night and in the morning. Particularly do they throng the wires near the creek, which flows north and south through the marsh, and which, it is inter- esting to observe, forms a natural highway for the Swallows as they go to and from their roosts. On the sides of this road are several small maple trees, to which the Swallows often resort in such numbers that their foliage trembles as though in a strong breeze, it not being the birds’ object to perch in the trees, but to flutter among the dew-laden leaves, and apparently bathe in the moisture they contain, while between the baths they rest on the smaller terminal twigs, when they are very difficult ‘o[Id qnoqe Surjuny sou PUB OIIM UO SMO[[PMG 901], “OG WHERE SWALLOWS ROOST 108 to observe.*® This habit does not appear to have been previously recorded, and I am by no means certain that the explanation offered is the true one. Frequently one or more flocks, varying in size from eight or ten to several hundred birds, may be seen in the road, where I at first supposed they were “dusting,” but soon noticed that most of the birds after alighting in the road were motionless. They did not move about as though searching for food, but occasionally the actions of a pair enabled one apparently to determine the sex of each individual, and more often a bird would pick up a bit of dried grass and fly up into the air with it. Sometimes it was carried fifty yards or more and then dropped; at others, the birds would carry it to the telegraph wires above, and drop it after perching a moment. Without exception, all the birds seen to alight in the road were in the dull, immature plumage of birds of the year, and in their actions, as Mr. William Brew- ster has remarked (The Auk, 1898, p. 194), they evi- dently gave a premature exhibition of the procrea- tive and nest-building instincts.” Additional evidence of the possession of inher- ited knowledge was apparently given by many Tree Swallows, who were frequently seen hovering about a pile standing in the creek.” At first it was sup- posed that these birds were feeding on insects which had alighted on the pile; but the number of birds— often a dozen or more—seen fluttering about it, and the persistency with which they remained there, forced the conclusion that in a wholly unreasoning way they were looking for a nesting site. 104 BIRD STUDIES WITH A CAMERA Swallows are not known to migrate by night, and, so far as I am aware, no single Swallow has ever been found among the thousands of night- flying birds which have perished by striking light- houses. The Swallows, therefore, when migrating 1. Immature Tree Swallows gathering nesting material. Or probably leave the marsh during the day, but in what manner who can say ? Several times when crossing the marshes on the cars I have observed gatherings of Swallows which made the immense flocks observed daily in August WHERE SWALLOWS ROOST 105 and September seem little more than a family of birds. They appeared in the distance like a vast swarm of gnats; it was as though all the Swallows in the marsh had collected in one great storm of birds. The significance of this movement I have never had the fortune to determine, but it seems highly probable that it is connected with the inau- guration of an actual migration toward the birds’ winter quarters. TWO DAYS WITH THE TERNS | =p = |ERNS are useless for food, and can “| not therefore be classed as “ game birds.” So far as we know they are of no special economic value. Consequently, when one protests against their practical annihila- tion for millinery purposes, he is not infrequently answered: “ Well, what good are they ?” The question exposes so absolute a failure to appreciate the bird’s exquisite beauty and unex- celled grace—such a discouraging materialism—that one realizes the hopelessness of replying. I confess I find it impossible to describe satisfac- torily just what the presence of Terns along our coast means to me. It is not alone their perfection of color, form, and movement which appeals to one, but also the sense of companionship they bring; and doubtless this feeling is emphasized by the impres- _sive loneliness of the sea, which makes anything alive doubly welcome. And so the coming of a single one of these beautiful creatures changes the character of the bay or shore. With unfailing pleasure one watches its marvelously easy flight, its startling darts for its food of small fish, and when it disappears the scene loses a grateful element of life. 106 {TWO DAYS WITH TIE TERNS 107 A milliner’s hunter or fisherman, however, might have made a very different reply to the unimagina- tive individual who asked the value of Terns. The former would have told him that they were worth about ten cents each for hat trimmings; the latter would have said that their eggs made excellent omelets; and each has done his best—the one to lay all Terns on the altar of Fashion, the other to see that none of their eggs escaped the frying pan. In the meantime a number of bird lovers have taken up the battle for the Terns in their few re- maining strongholds, and the brief history of Tern destruction and protection is full of suggestive in- cidents. It was about twenty years ago that Terns first found favor in woman’s eyes, and during the few succeeding years hundreds of thousands of these birds were killed on the Atlantic coast for milliners. Cobb’s Island, on the coast of Virginia, is credited with having supplied forty thousand in a single season, and, as one of the killers recently confessed to me that he knew of fourteen hundred being killed in a day, the story is doubtless true. Their delicate white and pearl-gray feathers were, of course, badly blood-stained; but good and bad, the skins were washed and then thrown into a barrel of plaster, which was rolled up and down the beach until the moisture was absorbed from their plumage. A Long Island taxidermist used a patent churn for this purpose. The destruction at other favorable points was proportionately great, and in two or three years one 108 BIRD STUDIES WITH A CAMERA looked in vain for the Terns which had previously so enlivened our shores. The protection afforded by an insular existence was now given a practical and striking illustration. The Terns which nested on the mainland or near- lying sand bars were soon extirpated, but on cer- tain less accessible, uninhabited islets, they still sur- vived. Thus all that were left of countless numbers of these birds which once inhabited the shores of Long Island were to be found on the Great Gull Island, while Muskeget and Penikese, off the Massachusetts coast, contained the only large colonies of Terns from Long Island to Maine. The existence of the Gull Island colony being threatened by collectors, the influence of several bird lovers secured the ap- pointment of the keeper of the lighthouse on the neighboring islet, Little Gull, as a special game warden to enforce the previously useless laws sup- posed to protect the Terns. The result was both encouraging and instructive. In two years it is estimated that the colony increased from two thousand to four thousand, and it was hoped that it might prove a nucleus from which the ad- joining shores would eventually be restocked with Terns. But the Government at Washington selected Great Gull Island as a desirable point for fortifica- tions, and before even this suggestion of war the poor Terns disappeared. For one season the labor- ers employed by the Government feasted on Terns’ eggs; then the gradual occupancy of the eighteen acres composing the islet forced the birds to seek homes elsewhere. TWO DAYS WITH THE TERNS 109 Hence it follows that if one would see Terns in numbers on the middle Atlantic coast to-day, he must journey to two small islets off Massachusetts, which thus far have afforded them a refuge. Inter- esting it is to recall that on Martha’s Vineyard, lying between the two, are found the only living repre- sentatives of the Heath Hen, or Eastern Prairie Hen, which was once locally abundant in certain parts of the Eastern and Middle States. In 1889 I visited the Terns of Great Gull Island, and a desire to be again surrounded by these birds, and perhaps secure photographs of them and their way of living, brought me on July 16, 1899, to Wood’s Holl, Massachusetts, en rowte to whichever Tern headquarters it might prove most convenient to reach. Quite unexpectedly there proved to be a small colony of Common and Roseate Terns on three islets, known as the Weepeckets, standing in Buzzard’s Bay, near the entrance to Wood’s Holl. In all, there were probably between three and four hundred birds, of which by far the greater number appeared to be domiciled on the largest of the three islands. This contains from ten to twelve acres of sand, grown with beach grass, scrub sumach, bayber- ries, and a few stunted pines about two feet in height. On this apparently uninviting bit of land I passed two delightful days alone with the Terns. The ac- companying photographs tell far more of the birds than pen can well express, but they convey no sug- gestion of the pleasure I experienced in again finding myself among them. 110 BIRD STUDIES WITH A CAMERA The birds were nesting on the upland, on the sloping grass bank, on the northwest side of the is- land, and on the rocky beach at its base. In the two first-named locations most of the nests were lined with grasses, but occasionally they consisted of only y el Ag “hee 52. Nesting site, nest, and three eggs of Common Tern. A nearer view of nest with sitting bird is shown in Nos. 63 and 64. a slight, bared depression in the earth; while the eggs along the beach were, as a rule, deposited on wisps or piles of driftweed. There were perhaps six or eight Roseate Terns, the others were apparently TWO DAYS WITH THE TERNS 111 all Common Terns, but as I am unfamiliar with the very similar Arctic Tern, it is possible that this species may have been present. A Tern colony is in some respects a unit. The alarm of one bird is shared by all, and before the boat’s keel grated on the sandy beach of the largest Weepecket, the snowy - breasted birds, which in a group were resting there, had taken flight, and with their “ singular call told all the other Terns on the is- land of my invasion. At once the birds gath- ered and, hanging in a flock overhead, pro- tested most vigorously against my intrusion with their purring, vibrant te-a-r-r-r. This cry never ceases so long as one remains near their home; it rings in the ears for days afterward, and one need only to recall it to form a clear mental picture of a sky full of hov- ering Terns. Occasionally this monotone was punc- tuated by a loud, reedy cack as a Roseate Tern dashed by, or as some half-distracted bird, whose nest was doubtless near, screaming, dived close to my head with a sudden, startling swish. It seemed almost as though the bird would pierce me with its sharply pointed bill; and if it could have managed to go through the rim of my hat without damage to either of us, [should have been very glad to have 53.

Some were on the upland, snugly placed in the grass or near a large stone,” and with pretty surroundings of yarrow, sumach, or bending grasses ; others were on the little shelves of the steep westerly bank of the islet ; and others still on bits of seaweed among the pebbles and rocks which here formed the beach.® No attempt was made to take advantage of the concealment of- fered by the groups of bowlders scattered along the beach, and beneath which the birds might have hid- den effectively, it be- ing presumably their object to select a site from which they could readily detect any cause for alarm. As a rule, their nests contained one or two eggs, only a single nest being seen with three. Although by this time birds of the year should have been on the wing, few young of any age were seen—a condition which was doubtless explained by the fact that the birds, thus far, had been too much occupied furnishing the members of boating parties with souvenirs of their day’s outing, to give atten- tion to their own household affairs, Wig. iy Peasy 2 3 54.

TWO DAYS WITH THE TERNS 113 However, the few young that were seen gave a most interesting exhibition of their instinctive appreciation of the value of both their protective colors and the power of their legs. As long as they 55.

This observation was verified later on Penikese,®” where young were numerous, and the habit was well shown by the young bird figured.” He was discovered squatting among the rocks, where he remained, practically at my feet, while I set up my tripod and deliberately made his picture—during which operation so inconspicuous was he that I in- variably had to hunt for him each time I removed my eyes from the exact spot in which he was crouch- ing. Wishing now to show him to better advantage, he was picked up and placed on a wisp of drift- 9 114 BIRD STUDIES WITH A CAMERA weed. At once his manner changed. My touch had broken the spell; what could be felt could be seen, and, whereas before he had been as motionless as the pebbles about him," his one object now was to get out of sight as speedily as possible. Consequently, time after time, the moment I took my hand from him he was off, and it was only by squeezing the bulb the moment he was released that I succeeded finally in securing his picture on the seaweed. Young Terns, apparently, spend at least two days in the nest, during which time they are brooded oe ©
