The greater part of the illustrations in this report have been copied (some alterations as to positions, etc., have been made in nearly all) from the small edition of "Audubon's Birds of America." By copying from said work which is regarded by competent critics as containing many of the finest portrayals of birds that have ever been published, the cost (ten to twenty-five dollars per plate) of original drawings was saved. The birds— most of the smaller species are about two-thirds or one-half the natural size ; in larger species the reductions are greatei*— have been colored from specimens in the author's collection, or from those kindly loaned to him by Prof. Robert Ridgway, Curator Department of Birds, United States National Museum, Wash- ington, D. C. Notwithstanding the fact that the " order to print " restricted the number of colors, the lithographer has, with the most careful efforts, succeeded in doing his work so ac- curately, that with a very few exceptions the reproductions are superior to the originals.

The State of Pennsylvania is situated between 39° 43' and 42° 15' north latitude, and between 74° 42' and 80° 35' west longitude from Greenwich. It is bounded on the north by New York and Lake Erie; on the east by New York and New Jersey, being- separated from the latter state by the Delaware river. Its length from east to west is about three hundred and ten miles, and about one hundred and sixty miles in width (" except at the angle at Lake Erie where it is one hundred and seventy-five "). It contains an area of 28,808,443 acres, of which only about 15,004,962 were improved in 1889. "FACE OF THE COUNTRY. — No state in the Union presents a greater variety of sur- face than Pennsylvania. Though they do not rise to any great elevation (seldom above 2,000 feet), its mountains spread over about one-fourth of the state in parallel ridges, in a direction generally from northeast to southwest, and occupy the south- ern, central and eastern counties. Though all forming parts of the great Appala- chian chain, they are known by various local appellations. Commencing below Easton, on the Delaware, we have the South mountain ; then in order, proceeding wes.t or northwest, the Blue or Kittatinny mountain (both entering the state from New Jersey, and passing southwest into Maryland), and the Broad mountain, which lies south of the North Branch of the Susquehanna. We now cross the river just mentioned, but still have with us the Broad mountain, under the name of the Tuscarora ; passing which, we come (upon another ridge, lying mostly south of the Juniata river, known as Sideling Hill ; which is succeeded in turn by the Allegheny mountains proper, the dividing ridge between the Atlantic slope and the Mississippi valley. Descending the very gradual Ohio slope, we cross two inferior but well- defined chains, known as Laurel and Chestnut Ridges. As before stated, these mountains do not rise to a great height ; the South mountain is within 1,000, and the Blue mountains within 1,500 feet. Broad mountain is said to rise higher above its immediate base than the Allegheny range, but to be inferior to them in elevation above the sea. These different ranges are separated by valleys, now contracted within narrow limits, and now spreading out to a width of from fifteen to thirty miles. The entire belt in Pennsylvania spreads over a space of two hundred miles — the greatest breadth the Allegheny range attains in its whole course from Maine to Alabama. In the southern part of the state the mountains become high and rug- ged hills ; the west is also hilly, and the southeast and northwest moderately so, but occasionally level. The rivers of the western part of the state, cutting their way through the table-land, present sometimes precipitous shores of several hundred feet in height, and many valleys bear evident marks of their having been formed by running water." (xi) xii BIRDS OF PENNSYLVANIA. "CLIMATE.— The climate of Pennsylvania is variable, and liable to sudden extremes, having sometimes the heat of the Carolinas, and at others the cold of Canada, but in periods generally of only three days, intermingled in summer with sharp winds from the northwest, and mitigated in winter by the milder breezes from the south- west Periods of warm weather sometimes occur in January and February. * * * The mountainous region has a greater degree of cold, and the snows are deeper and lie longer than in other portions. In the west the climate is milder and less vari- able than in the east" " RIVERS, LAKES, ETC.— The only lake of importance in this state is Lake Erie, which forms its northwest boundary for about fifty miles. The Delaware, which rises in the southeast part of New York, and flows southerly, separates New York and New Jersey from Pennsylvania and Delaware, and empties into Delaware Bay. It is navigable for large ships to Philadelphia, about ninety-six miles from the sea, and for sloops and steamboats to Trenton, thirty miles further up. The Susque- hanna, the largest river in the state, enters Pennsylvania from New York, and flow- ing southerly for four hundred miles, crosses the entire state, dividing it into two unequal portions, having the larger part on the west This river is not navigable, except at high- water in the spring and autumn, when large quantities of timber are floated down it in rafts. * * * Owing to its rapid descent to within a few miles of the Chesapeake Bay, into which it flows, it is but little affected by the tides. Its principal tributaries are the West Branch and Juniata from the west, and the Swatara and Conestoga from the east Between the Susquehanna and Delaware are the Lehigh and Schuylkill, affluents of the Delaware, and each about one hundred miles in length. The Ohio, which is formed by the union of the Allegheny from the north, and the Monongahela from the south, drains the western part of the state, having about fifty miles of its course in Pennsylvania. It is navigable for large steamboats to its head at Pittsburgh. The Allegheny is about three hundred and the Monongahela two hundred miles in length, and both, at high-water, are navi- gable, the former two hundred and the latter sixty miles, for small steamers. The Youghiogheny, a branch of the Monongahela, and the Beaver, a branch of the Ohio, are small rivers. Canals coast most of these rivers, except the Monongahela and Youghiogheny, to a greater or less extent"— LippincoWs Gazetteer. Lake Erie is the only lake of commercial importance, but there are nume- rous small lakes in many parts of the state, especially in the counties of Susquehanna, Wayne, Pike and Wyoming, where different kinds of water fowl repair during- migrations. Although numerous species of aquatic birds visit Conneaut Lake, in Crawford county, and Lake Pleasant, in Erie county, they are found in greater numbers at Presque Isle Bay (also called Erie Bay) than elsewhere in the state. In this present work the classification, nomenclature and geographical limits correspond with the A. O. U. Check List of North American Birds,* a publication representing the joint labors of a " Committee on Classifi- sation and Nomenclature " appointed by the Union at its first congress, held in New York city, September 26-29, 1883.

BIRDS OF PENNSYLVANIA. ORDER PYGOPODES. DIVING Brai)S; ; SUBORDER PODICIPEDES. GREBES. FAMILY PODICIPID-ffi. GREBES. THE GREBES. Grebes during the spring and fall migrations are very generally distributed throughout the state, and during niild winters birds of this family are often seen about the larger lakes, ponds and rivers in different sections of the commonwealth. Although these birds are generally observed singly or in pairs, occasionally, a good- sized flock is to be found. In relation to the Grebes in general it can be stated that, unless flying, they are almost always to be seen in the water. The several species of this family, owing to the posterior situation of their legs, move with considerable difficulty when on the ground, over which they go in a slow, floundering manner. Grebes, like some other kinds of aquatic birds when wounded, will conceal them- selves in weeds and grasses, which grow so luxuriantly in their favorite watery retreats, where they will remain for a considerable period of time with only their slender, tapering bills above the water's surface. They swim and dive with the utmost facility ; when swimming beneath the water's surface, either in quest of prey or to escape capture, it is said they use their wings in the same manner as when flying in the air. Their well-known habit of diving when alarmed, and particularly if shot at, has won for them the common name of u Hell-divers." The Grebe's nest consists of a thick, matted mass of vegetation, such as reeds, flags, grasses, etc. Sometimes the nest is built close to the water, but usually, according to Mr. Ridg- way,* it is to be found "floating upon the surface of the water in grassy or sedgy ponds or marshes." The same eminent authority describes the eggs as follows : "2-5, dull white, bluish white, or very pale bluish green, usually stained more or less (often quite deeply) with light brown, by contact with decomposed vegetable matter." With the exception of the Pied-billed Grebe (Podilymbus podiceps), rep- resentatives of this family occurring in Pennsylvania breed, generally, north of the United States. Grebes subsist chiefly on fishes, frogs, various aquatic insects — especially beetles— and to a limited extent on different water plants. They confer no special benefits, nor are they in any particular detrimental to agricultural inter- ests. Their flesh, quite tough and disagreeable to the taste, is seldom eaten, the feathers, however, are considerably used by milliners, and by furriers for muffs, etc. For these purposes the beautiful silvery-white plumage of the breast and abdomen is taken. Bill acute and hard, variable in length, straight or decurved at end ; higher than wide. Head with a naked loral space, and furnished either with bristly or variously elongated feathers, usually called tufts or crests. These crests, which render the * A | Manual | of | North Americun Birds. | by | Robert Ridgway. | illustrated by4«4 outline drawings of the generic characters. | Philadelphia. | J. B.

Adults of both sexes are adorned with the parti-colored head, crests or ruffs, which disappear, however, when the birds assume their winter dress. The young, in winter, as well as the old birds, are very materially different from the adults in their nuptial plumage. Tail represented by a small tuft of downy feathers. Feet four-toed, all broadly lobed, but not webbed ; the three front toes are connected at base by webs ; hind toe, short free and elevated. Claws wide, flat and short, that of hind toe being very small. The peculiar paddle- like toes and the rudimentary tail will readily enable one to recognize a member of thfe'G-re be family.; ; • COLYMBUS LINNAEUS. Colymbus holbcellii (REINH.). Holboell's Grebe. DESCRIPTION. Adult. — Bill about two inches long, acute and tapering, somewhat shorter than the head and a trifle shorter than the tarsus ; upper mandible black except tomia at base and portion of base at sides which is yellow. Lower mandible chiefly yellow except on sides which are dark bluish or nearly black. Narrow, naked and blackish strip extending from eyes to bill ; legs and feet blackish on outside, greenish yellow 011 inside. Top of head and back of neck black, with a greenish tint and somewhat glossy ; the glossy green hue fades gradually at back of neck. Feathers of upper parts brownish-black, more or less glossy and edged with grayish ; primaries brown- ish ; secondaries white with black or brown shafts, some secondaries are tipped with brownish. Throat and side of head ash-gray, the latter separated from black of head by a white streak extending from under eye backward ; feathers about lower man- dible are also quite white ; front of neck and especially the sides reddish brown ; lining of the wings white. Under parts silvery white, more or less mottled with grayish, sides dusky. In some specimens the rich reddish-brown on sides of neck extends in small patches over the upper part of breast. Crests or rufts but slightly developed. Adult in winter and young. — Upper bill blackish-horn, yellowish at base and on tomial edges ; lower bill mainly yellowish ; eyes dark ; crests hardly notice- able ; upper parts brownish-black, head quite black ; throat, sides of head and abdomen white ; front part of neck and sides brownish-ash. Length about 18| inches ; extent about 32. Habitat.— North America at large, including Greenland. Also eastern Siberia and southward to Japan. Breeds in high latitudes, migrating south in winter. This bird, the largest of all the Grebe family found in Pennsylvania, migrates far northward to rear its young. Mr. E. W. Nelson, in his "Report upon Natural History Collections made in Alaska" states that " this species was not uncommon along the coast of Norton Sound in the fall, and a few isolated pairs nested each summer in the marshes. Along the course of the Yukon they are much more common, and breed in considerable numbers." Holboell's Grebe, called also the Bed-necked Grebe, is by no means as common with us as either of the other species hereafter mentioned. Specimens of this bird have been taken in differ- ent parts of the state during the spring, fall and winter months. From information which I have received, through the courtesy of naturalists and collectors in all sections of the state, it is learned that in the past twenty-five years only about a dozen of these Grebes have been cap- BIRDS OF PENNSYLVANIA. tured, identified and preserved in our commonwealth, and these, with perhaps two or three exceptions, have been secured on the Susquehanna and Allegheny rivers. In the spring of 1888 Mr. George P. Friant, re- siding at Scranton, Pennsylvania, obtained a fine adult male of this species which had killed itself by flying through the glass in a green- house of one of his neighbors. Mr. James S. Nease, a careful collector, residing in Washington, Pennsylvania, has observed this bird in his county only as a rare winter visitor. Mr. August Koch, the well-known Ly coming county (Penna.) natur- alist, in a letter of June 26, 1889, addressed to me, says, in reference to Holbcell's Grebe, " I know of three instances only, when taken in our locality (yet it may occur often). The first time in winter about twenty years ago ; next in the spring of 1886, when nine of these birds were noticed in a flock and several taken. My specimen is a male in spring dress. Another male in full winter plumage was kindly left to my dis- position by Mr. Charles H. Eldon; it was taken the winter of 1888." Mr. L. M. Turner, of Arctic fame, in his " 'Contributions to the Natural History of A laska" remarks that "the Eskimo name of this Grebe is E-td-td-tuk, from its note ta-ta-ta" The stomachs of two of these birds examined by me contained principally sand, blades of grass, small roots and feathers.

Length about 14 inches ; extent about 25 inches. Habitat. — Northern hemisphere. Breeds from northern United States northward. This species is recorded as quite a common winter resident through- out the United States, and although sometimes found nesting within our northern limits, it retires chiefly north of the United States during the breeding period (middle of May to middle of August). Audubon (Birds of America) states that he found, in Ohio, near Lake Erie, in the month of July, nests containing eggs in which incubation was well advanced. Dr. Coues (Birds of the Northivest) mentions that he has found it breeding at various points in northern Dakota, where, in June BIRDS OF PENNSYLVANIA. and July, he secured both eggs and young-, the latter newly hatched. This species is recorded by Mr. E. A. Samuels as nesting in more north- ern latitudes than New England. The Horned Grebe is an irregular sojourner, in Pennsylvania, from the middle of October until early in April. In the months of March and April this Diver is usually more numerous than at other times during its residence with us. Although generally observed singly or in pairs, and sometimes in parties of four, five or six, I have seen, on three occasions, in the past ten years, flocks numbering from twelve to twenty-five of these birds, during the spring migrations, on the Susquehanna, Lehigh and Delaware rivers. Dr. Walter Van Fleet and Burgess J. H. Ferguson, both of Eenovo, Clinton county (Pa.), recently informed me that in the latter part of March or early in April, 1884, large numbers of Horned Grebes appeared in vari- ous streams and ponds in central Pennsylvania, and remained for two or three days before passing northward. Mr. Ferguson says there were at least two hundred Grebes in the river at Renovo, where many were killed by gunners. In a small pool, less than one rod across, Dr. Van Fleet secured over twenty. Audubon, writing of the food of Horned Grebe, says : " I have observed in the stomachs of almost all that I have examined, a quantity of hair-like substances rolled together like the pellets of owls, but have not ascertained whether or not these masses are disgorged. * * * * The food of this species, while on salt water, is composed of shrimps, small fishes, and minute Crustacea. While on fresh water, they procure insects, leeches, small frogs, tad- poles, and aquatic lizards; they also pick up the seeds of grasses." The stomach-contents of nine of these birds which I have examined con- sisted mainly of sand, remains of fish, beetles and frogs and portions of green-colored aquatic plants. In the stomachs of three specimens I have found, in addition to other food-stuffs, small ball-like masses of feathers. I GENUS PODILYMBUS LESSON. Podilymbus podiceps (LINN.).

Habitat.— British provinces southward to Brazil, Buenos Ayres and Chili, includ- ing the West Indies and the Bermudas, breeding nearly throughout its range. The Pied-billed Grebe, or Dabchick, is a common spring and fall vis- itor, and in winter it is often, seen, especially in the southern counties of the state. The Dabchick is the only one of the Grebes which has been known, to naturalists, with whom I have corresponded on the mat- ter, to breed in Pennsylvania, but as a native the bird is rare, or if it breeds at all regularly with us, it retires to such secluded situations that collectors rarely find it. In the counties of Crawford and Erie Mr. George B. Sennett has observed the species as a "moderately common spring and fall migrant," and Mr. August Koch, of Williamsport, has noted it, in his locality, only as a spring and fall visitor. Dr. John W. Detwiller, naturalist, residing at Bethlehem, Northampton county, writes me he has found it breeding here. Prof. H. Justin Roddy, of the Millersville State Normal School, says : This Grebe about ten years ago bred in Perry county, Pennsylvania. The following interesting and valuable notes concerning the nesting habits of the Pied-billed Grebe are given by Mr. Langdon in his list- Summer Birds of a Northern Ohio Marsh : "The little floating island of decaying vegetation held together by mud and moss, which consti- tutes the nest of this species, is a veritable ornithological curiosity. Imagine a 'pancake' of what appears to be mud, measuring twelve or fifteen inches in diameter, and rising two or three inches above the water, which may be from one to three feet in depth ; anchor it to the bottom with a few concealed blades of 'saw-grass,' in a little open bay, leaving its circumference entirely free ; remove a mass of wet muck from its rounded top and you expose seven or eight soiled brownish-white eggs, resting in a depression the bottom of which is less than an inch from the water ; the whole mass is constantly damp. This is the nest of the Dabchick, who is out foraging in the marsh, or perhaps is anx- iously watching us from some safe corner near by. "The anchoring blades of coarse saw-grass or flags, being always longer than is necessary to reach the bottom, permit of considerable lateral and vertical movement of the nest, and effectually provide against drowning of the eggs by any ordinary rise in the water-level such as frequently occurs during the prevalence of strong easterly winds on the lake. A small bunch of saw-grass already growing in a suitable situa- tion is evidently selected as a nucleus for the nest, and the tops bent so as to form part of it. " During the day we invariably found the eggs concealed by a cover- 6 BIRDS OF PENNSYLVANIA. ing of muck as above described; but as we ascertained by repeated visits at night and in the early morning they are uncovered at dusk by the bird who incubates them until the morning sun relieves her of her task." SUBORDER CBPPHI. LOONS AND AUKS. FAMILY URINATORID-ffi. LOONS. THE LOONS. Loons live almost habitually in the water ; they dive with wonderful rapidity and skill, and are also remarkable for their ability of swimming long distances under the water, especially if endeavoring to elude their enemies. As divers they are the most expert of all birds. They retire during the summer season to high boreal re- gions to rear their young, and as cold weather advances migrate southward. During migrations Loons are most numerous about our seacoasts and on the large lakes in the interior. Like the Grebes they move over the ground in a slow, floundering and awkward manner, their flight, however, is rapid, and when migrating they generally fly at a considerable elevation. The shrill and mournful notes of these birds can be heaid at a great distance ; it is asserted by some that Loons, like the Cuckoos, are more frequently heard before a storm than at other times. The flesh of these birds is tough, dark-colored and "fishy." The white plumage of the under parts and the spotted feathers of the back are sometimes used by milliners and furriers. The nest is described as a rudely-built structure of reeds, grasses, etc., on the ground near the water ; the dark-colored and spotted eggs are said to be usually two in number. Bill long, hard, straight, tapering and sharp-pointed, being quite spear- like in appearance, and well adapted to catching their prey, consisting principally of fishes. Lores completely feathered. Head without crests or ruffs. Tall well developed, but very short and rounded. Legs situated far behind. Tibia mostly concealed in belly. Feet with four toes, the three in front long and wholly webbed. GENUS URJNATOR OUVIER. Urinator imber Loon ; Great Northern Diver. DESCRIPTION (Plate 51). Adult.— Bill and legs (dried specimen) bluish-black ; iris, red; head and neck dark bluish-green ; sides of head quite purplish ; lower part of neck glossy-green ; throat with transverse streak of six or eight distinct patches of white feathers ; tri- angular patches of white streaks on sides of neck, almost uniting behind and nar- rowing as they extend to front of neck, where they are about one inch apart ; upper parts and sides glossy-black, conspicuously spotted with white ; spots on lower part of back, rump and sides are small ; spots on back arranged in transverse rows, and increase in size from lower part of neck backward ; sides of breast black with white streaks, lining of wings, breast, abdomen and crissum white ; tail brownish- black, somewhat glossy above and unspotted. Young. — Top of head, back and rest of upper parts brownish-black ; chin, throat and lower parts white, sides of breast and sides brownish-black ; back unspotted (specimens are sometimes found in which the scapular and tertial feathers are quite well marked with the square white spots so conspicuous in the full plumaged adult) ; iris, brown ; bill (dried specimen) bluish-white, dusky on ridge and yellowish at BIRDS OF PENNSYLVANIA. base ; tarsi and feet brownish -yellow ; length about 32 inches ; extent about 55 ; bill along culmen about 3 inches. Habitat.— Northern part of Northern Hemisphere. In North America breeds from the northern tier of states northward ; ranges in winter south to the Gulf of Mexico. This bird, the largest of all the Divers, is about as large as a medium- sized domestic goose. The Loon, known to many as the Great Northern , Diver, is a regular and tolerably common spring and fall migrant, fre- quenting, principally, the rivers, larger streams and lakes. In the winter, when streams and other bodies of water are not frozen over, indi- viduals of this species are frequently to be found with us. Although not known to breed in Pennsylvania, these birds are sometimes seen here in the breeding season. Hon, N. F. Underwood, member of the Pennsylvania State Board of Agriculture, residing at Lake Como, Wayne county, and hunters living in Wyoming and Susquehanna counties, have informed me that solitary Loons are occasionally to be found throughout the summer months, inhabiting the numerous small lakes in the northeastern parts of this commonwealth. In Lycoming county Mr. August Koch says "the Loon is a common visitor of tener to be noticed in the spring than in fall, and occasionally single birds may be noticed in the first summer months." The Loon, ever cautious and vigi- lant, will dive at the flash of a gun and proceed under the water to a very considerable distance before reappearing. These birds, it is said, when endeavoring to elude their enemies, and also, at times, when in quest of food, swim under the water with greater rapidity than they fly through the air. Writing of the Loon, Nuttall says, in referring to its voice, " far out at sea in winter, and in the great western lakes, par- ticularly Huron and Michigan, in summer, I have heard, on a fine, calm morning, the sad and wolfish call of the solitary Loon, which, like a dis- mal echo, seems slowly to evade the ear, and rising as it proceeds, dies away in the air. This boding sound to mariners, supposed to be indic- ative of a storm, may be heard sometimes for two or three miles, when the bird itself is invisible, or reduced almost to a speck in the distance." The stomach contents of seven Loons, captured during the winter months in Chester, Delaware, Clinton and Lehigh counties, Pa., con- sisted entirely of fish-bones and scales ; two other specimens, purchased in the winter of 1881 from a game dealer in Philadelphia, were found to have fed on small seeds and portions of plants, apparently roots. Indi- viduals of this species are, it is said, sometimes found in the Hudson Bay region weighing as much as fifteen or sixteen pounds apiece. The female is somewhat smaller than the male. The weight of three females taken in Pennsylvania in the early spring ranged from seven to seven and three-quarter pounds each, and two males, one taken on the Lehigh river, in the fall, the other captured in Warren county, on the Allegheny river, in the spring, tipped the scales each at nine and three-quarter pounds. BIRDS OF PENNSYLVANIA. Urinator lumme (GUNN.). Red-throated Loon. DESCRIPTION. Bill rather slender, about two and one-quarter inches long and bluish-black ; front and sides of head, chin, upper part of throat and sides of neck bluish-gray ; crown, hind neck, sides and upper parts generally brownish-black, glossed, more or less, with greenish, and spotted or streaked with white ; front of neck with a longitudinal and triangular patch of rich reddish-brown ; under parts white ; legs (dried speci- men) brownish-black ; iris, red in adult, and reddish-brown in young. The young and adults, in winter, lack the bright chestnut-colored patch on fore-neck, and plu- mage of upper parts generally is brownish-gray, conspicuously spotted with white ; length about 26 inches ; extent about 44 inches. Habitat. — Northern part of Northern Hemisphere, migrating southward in winter nearly across the United States. The Red-throated Loon, a rare and irregular visitor in this locality has been taken in the late fall, winter and early spring-, in different parts of the state. Specimens have been captured in Lycoming-, Clinton, Northampton and Philadelphia counties, and I have been informed that on Lake Erie, in the neighborhood of Erie city, this bird is often met with, especially late in the autumn. The individuals which come as far southward as Pennsylvania are usually young-. Red-throated Loons are much more common along- the sea-coast — from Maine to Maryland — in the winter season, than in the interior, and in the summer or breeding- time (June and July) they retire much farther north than the Great Northern Diver. The food of this bird is similar to that of the previ- ously described species. FAMILY ALGID JE. AUKS, MURRES AND PUFFINS. THE AUKS, ETC. The members of this family, numbering about twenty-five species and subspecies in North America, are all exclusively marine. Many of them inhabit almost con- stantly the northern seas. Species are much more numerous on the Pacific coast than on the Atlantic; but few birds of this family have been observed in Pennsyl vania and doubtless those taken here have been driven inland by severe storms. These birds are gregarious, certain species, especially during the breeding season, assembling in great numbers. One egg is laid on the bare ground or in crevices of rocks ; high cliffs along the ocean, it is stated, are usually the favorite breeding-sites. Like the Loons, most of these birds move over the ground in an awkward manner ; their flight, however, is quite rapid and they swim and dive with great address. When swimming under the water in quest of prey, particularly fish, on which they principally subsist, they employ their wings in the same manner as when flying m the air. The eggs and young of many of these birds are, it is said, quite highly esteemed as food by natives in Arctic countries, where the tough skins with their thick coatings of feathers are also considerably used to make articles of wearing apparel. In birds of this family the hind toe is absent, and the three front toes are united by a continuous web. S ""! BIRDS OF PENNSYLVANIA. SUBFAMILY FRATERCULIN^. PUFFINS. GENUS FRATERCULA BRISSON. Fratercula arctica (LiNN.). Puffin. DESCRIPTION. Adult, in winter. — Bill quite stout, flattened laterally and nearly as high as long; both mandibles with curved and distinct grooves ; bill and legs (dried skin) brown- ish yellow ; upper parts and space on front of neck brownish-black ; throat and sides of head grayish-white, under parts white. Length about 13^ inches ; extent about 24 inches. Habitat. — Coasts and islands of the north Atlantic, breeding on the North Ameri- can coast from the Bay of Fundy northward. South in winter to Long Island, and casually further. The Puffin or " Sea Parrot," as this bird is frequently called, has been observed in Pennsylvania only as an accidental winter visitant. But one specimen of this species has, so far as I can learn, been captured in our state. This bird, now in the possession of Mr. Joseph Krider, of Philadelphia, was killed by a gunner in the winter, about 1876, along- the Delaware river, near Chester city. The Puffins, according to differ- ent writers, breed either in crevices of high rocks or cliffs on the sea- coast, or in burrows which they dig in the ground. These holes, it is stated, are usually excavated to the depth of about three feet. " Their food consists of various kinds of small fish, particularly sprats, the smaller kinds of crabs, shrimps and sea-weeds, and it is not improbable but that their sudden migrations are regulated by the presence or ab- sence of certain kinds of fish on which they delight to feed." — Nuttall. SUBFAMILY PHALERIN^I. GUILLEMOTS, ETC. GENUS CEPPHUS PALLAS. Cepphus grylle (LiNN.). Black Guillemot. DESCRIPTION. Adult, in winter. —Bill black, sharp-pointed, quite straight and shorter than the head ; head, neck, under parts, rump, and space on wing white ; back, wings and tail dark brown or black, mixed with white ; tarsi reddish. Length about 13 inches ; extent about 23 inches. Habitat.— Coast of northern Europe, south to Denmark and the British Islands. Coast of Maine, south in winter to New Jersey. The Black Guillemot, an inhabitant of the dreary coasts and islands of the north Atlantic, is a rare and irregular straggler in winter on the Atlantic coast, southward to New Jersey. In Pennsylvania this species has been observed as an accidental wanderer in winter. A specimen in the museum at Lancaster city, Pa., was taken, it is said, on the Susque- 10 BIRDS OF PENNSYLVANIA. hanna river in Lancaster county. Messrs. C. D. Wood and John Krider had in their possession two or three of these birds, which, they stated, had been captured in the neighborhood of Philadelphia. Prof. H. Jus- tin Koddy, of Millersville State Normal School, records the capture of a Black Guillemot in the late fall or winter in Perry county, Pa. SUBFAMILY ALLINJE. DOVEKIES. GENUS ALLE LINN. Alle alle (LiNN.). Dovekie ; Sea Dove. DESCRIPTION. Adult, in winter :— Bill very short and thick, upper mandible curved; upper parts brownish-black, scapulars edged and streaked with white, and secondaries tipped with same ; chin, throat, sides of neck and under plumage generally white ; bill, black ; iris, dark-brown ; tarsi (in dried skin) brownish. Length about 8£ inches ; extent about 15| inches. Habitat. — Coasts and islands of the north Atlantic and eastern Arctic Oceans ; in North America south in winter to New Jersey ; breeds in high northern latitudes. The Sea Dove or Little Auk, as this bird is sometimes called, very rarely migrates in winter as far southward as the coast of New Jersey. During the past ten years I have seen two specimens that have been captured in winter on the Delaware river near Philadelphia. Both of these birds were taken shortly after violent storms. In the fall of 1886 Prof. H. Justin Roddy, of Millersville, Pa., obtained one of these birds in Perry county, Pennsylvania. NOTE. — Cepphus mandtii (Mandt's Guillemot) and Uria lomvia (Briin- nich's Murre), both of which were mentioned in the first edition of Birds of Pennsylvania, have been omitted in this report, as I am not certain that either have been taken in our state. ORDER LONGIPENNES. LONG-WINGED SWIMMERS. FAMILY STERCORARIID-ffi. SKUAS AND JAEGERS. THE JAEGERS. The Jaegers or Skua Gulls inhabit principally the sea-coasts ; they also irequent the large inland waters, especially the great lakes. Two genera and four species are recorded as belonging to the fauna of the United States. In Pennsylvania the Jae- gers have been noted by various naturalists only as very rare andirregular visitants. These hardy, bold and predacious birds retire mostly to the dreary arctic solitudes to rear their young. During the winter season, or at other times when migrating, they are generally found singly or in pairs, but when breeding, a well-known writer says they congregate in large numbers and nest in tufts of grass, on rocks or even on the bare ground ; the eggs, two or three in number, are described as being nearly three inches long and a little less than two inches in width, and are dark-colored, BIRDS Of1 PENNSYLVANIA. 11 spotted or blotched with different shades of brown and grayish. Dr. Elliott Coues says: "The Skua Gulls are eminently rapacious, whence their name of 'Jager' (hunter) ; they habitually attack and harass terns and the smaller gulls, until these weaker and less spirited birds are forced to drop or disgorge their prey. Their flight is vigorous ; lashing the air with the long tail, they are able to accomplish the rapid and varied evolutions required for the successful practice of piracy. Thus in their leading traits they are marine Raptores, whilst the cered bill furnishes a curious analogy to the true birds of prey." Thomas Nuttall, writing of the Jaegers, says : " They also often provide for them- selves, feeding on floating objects, as they never dive, and sometimes live on the flesh of cetaceous animals, shell-fish, molusca, eggs and young birds." The head and eyes are large ; neck rather short and stout ; bill strong, hard and hooked at tip ; "covering of the upper bill not entire, as in the Laridce, the posterior half being furnished with a horny cere, the lower edge of which overhangs the nostrils ; toes fully webbed ; hind toe very small ; claws large and strong, curved and very acute ; tail slightly rounded, but the central pair of feathers projecting a greater or less dis- tance beyond the rest." The Jaegers like the Gulls and Terns (Laridse) swim most buoyantly, but are incapable of diving. Representatives of this family, both adult and young, vary greatly in their plumage. GENUS STERCORARIUS BRISSON. Stercorarius pomarinus (TEMM.). Pomarine Jaeger. DESCRIPTION. "Adult. — Front, crown of the head, back, wings and tail, blackish-brown; sides and back part of the neck bright-yellow; throat and entire under plumage white, with a brand of brown spots extending across the upper" part of the breast; sides and lower' tail coverts barred with brown ; shafts of quills and tail feathers white; bill greenish-olive, black at the tip ; legs and feet black ; the middle tail feathers extend beyond the others for about 2 inches ; they are rounded at the end, and of a uniform breadth throughout. " Young birds have the plumage of the upper parts blackish-brown ; of the lower, grayish-brown, with the feathers of the abdomen and lower tail coverts margined with dull-ferruginous ; tarsi and base of the toes and webs yellow. " — Baird's B. of N. A. Length about 20 inches ; extent about 48 inches. Habitat. — Seas and inland waters of northern portions of the Northern Hemi- phere, south in winter to Africa and Australia and probably South America. Not known to occur in winter on the Atlantic coast of North America north of Long Island. The Pomarine Jaeger, known to the fisherman on the coasts of Maine as " Gull Hunter," resides during the summer or breeding season in high boreal regions, but when the young are able to provide for them- selves both the old and young migrate southward, and frequent mainly the shores of the ocean. In this state the Jaeger occurs only as an acci- dental visitor. The late Prof. S. R Baird, in the summer of 1840, secured a specimen at Harrisburg, on the Susquehanna river ; another example of the same species is recorded as having been obtained by the late Vin- cent Barnard, of Chester county, in Lancaster county, Pa., on the Susque- hanna In the winter of 1885 or 1886, Mr. C. D. Wood, a Philadelphia 12 BIRDS OF PENNSYLVANIA. taxidermist, mounted one of these birds, which had been shot by a hunter in Sullivan county, Pa., near Eagle's Mere, a popular summer resort on the Philadelphia and Reading railroad. Stercorarius parasiticus (LiNN.). Parasitic Jaeger. DESCRIPTION. "Adult,— Upper part of the head blackish-brown; nape and sides of the neck yellowish-white; remainder of upper plumage blackish-brown; wings and tail darker ; shafts of the primaries white ; under plumage white ; bill bluish at the base, black at the point ; tarsi and feet black ; the central tail feathers extend beyond the others about three inches ; they taper slightly, varying but little in breadth until near the end, where they are abruptly acuminated, differing in this particular from all the other species. Young. — Head and neck streaked with dark brown and brownish-yellow ; lower parts spotted or barred with the same; upper parts brownish or dusky and brownish- yellow. Length about 18 inches ; extent about 40 inches." — Bawd's Birds of N. A. Habitat. — Northern part of northern Hemisphere, southward in winter to South Africa and South America. Breeds in high northern districts, and winters from the Middle states and California southward to Brazil and Chili. The Parasitic Jaeger, like the preceding species, occurs in Pennsylva- nia only as a rare and irregular straggler. Dr. Turnbull (Birds of Eastern Pennsylvania) records the capture of one near Philadelphia by the late John Krider. In October, 1874, Mr. Merrick Low shot, at the head of Erie bay, a fine specimen of this bird, which is now in the col- lection of my friend, Mr. George B. Sennett, of Erie city. Dr. Walter Van Fleet mentions both the Pomarine and Parasitic Jaegers as strag- glers in Clinton county, Pa. Never having had an opportunity of studying this species in life, I quote the following interesting extracts from Mr. E= W. Nelson's report (Natural History Collections in Alaska} : " During summer these Jaegers show a much greater preference for marshes and the low, barren grounds so common in the north, than they do for the vicinity of the sea- coast. At the Yukon mouth, and near St. Michaels, they arrive with the first open water, from the 10th to the 15th of May. The snow still lies in heavy drifts on most of the open country, but the Jaegers take pos- session and feed upon the shrew-mice and lemmings which are common on this ground. By the last of May they are very common, and twenty or thirty may be seen in a day's hunt. " Birds in the black plumage are rare in the spring, but are sometimes seen, and at the Yukon mouth, on May 31, 1 found a pair in this plum- age mated. The eggs are laid on mossy knolls or uplands, in their haunts, about the 5th of June. The nest is merely a depression in the moss, containing two eggs. The young are on the wing by the end of July and early August. The last birds move southward or keep out to sea after the 20th of September. On cloudy days, or in dusky twilight, BIRDS OF PENNSYLVANIA. 13 these birds have a habit of uttering loud, wailing- cries, interspersed with harsh shrieks, which are among the most peculiar notes heard in the northern breeding grounds. At all times the Jaegers are given to wan- dering, and one is likely to find them almost anywhere along the coast. They are not infrequently seen harrying terns or gulls to make them dis- gorge fish just caught. If successful they dart down and, rising under the falling morsel, catch it in their capacious mouth. This robbery is often performed by two birds in unison, but whether the birds alternate in disposing of the spoil or not could not be learned. * * * * They are very greedy, and frequently swallow so much that they are unable to fly until a portion is disgorged." FAMILY LARUXflS. GULLS AND TERNS. SUBFAMILY LARIN^l. GULLS. THE GULLS. Only two or three species of this group, represented by over twenty-five species and subspecies in North America, have been observed by naturalists to occur in Pennsylvania with any degree of regularity. None breed in this commonwealth where they are found only as transitory sojourners during the spring, fall and win- ter months. Gulls vary greatly in size ; some are classed among the largest of the marine birds, while others are but little larger than their near relatives — the terns. In these birds the body is more robust than in the terns, the bill is hooked, the tail is generally even and the toes are fully webbed. They are light, easy and graceful swimmers, but are unable to dive, though some of them secure their food by plunging for it in the same manner as terns. The sexes are similar in color, and the female is usually a trifle smaller than the male. Gulls differs, greatly in their plumage, but the adults are usually white with a dark, or bluish-gray mantle ; in some species the head — especially in the breeding season —is enveloped in a dark hood. The young are wholly different from the old birds, being much darker and usually more or less spotted or mottled with gray and dif- ferent shades of brown. Gulls generally associate in large flocks, not only when breeding but also during the spring and fall migrations, and in winter. They in- habit chiefly the sea-coasts and large inland waters ; some kinds, however, and es- pecially the smaller species when migrating, and also frequently in winter, ascend to a considerable distance many of the principal rivers emptying in the bays and ocean. Gulls are gluttonous and voracious, feeding on almost any kind of animal sub- stances, fish, however, is their main article of diet. These birds, with a few excep- tions, breed beyond the northern limits cff the United States, and most of them re- tire during the season of reproduction to the arctic regions. The nest is usually built on the ground or near it, some species construct rude nests of twigs, grasses, moss, etc., while others, it is said, deposit their eggs either on the bare ground or on rocky ledges. The eggs, two to four in number, are variously spotted with different shades of black, brown and gray. The loud, shrill arid unmusical notes of these birds are most frequently heard when they are on the wing ; they are, also, especially noisy when feeding, or when their nesting places are approached. The flesh of the old bird, particularly that of the larger species, is quite tough and unpalatable. The flesh of the young birds, especially the smaller kinds, is sometimes eaten by fishermen and hunters. Al- though the gulls are seldom used for food, unless it is by the Eskimo and other residents of the northern regions, who, it is stated, esteem the flesh of several species as great delicacies — it is a noteworthy fact that the silvery and downy feathers of these birds are largely used by our milliners. 14 BIRDS OF PENNSYLVANIA. GENUS LARUS LINNAEUS. \ Larus argentatus smithsonianus OOUES. American Herring Gull ; Big Gull ; Winter Gull. DESCRIPTION. Adult.— Head, neck, rump, tail and under parts white ; mantle dull pale-blue ; primaries tipped with white, and barred with black ; bill yellow, with reddish spot ; tarsi, flesh color ; iris, yellowish-white. Young. — Mottled with grayish-brown, white and light pearl-blue, the latter in patches on upper parts ; primaries dusky ; bill brownish-yellow, dark towards end ; iris, brown ; length about 25 inches ; extent about 59 inches. Habitat. — North of America generally, breeding on the Atlantic coast from Maine northward ; in winter south to Cuba and lower California. This species is a rather common spring and fall migrant on Lake Erie, where, during the winter months, if the weather is not exceedingly cold, these birds are also sometimes seen singly or in small companies of five or eight. Throughout the state in general this species occurs as quite a rare and irregular visitor. On the Delaware river, near Phila- delphia, and on the Susquehanna, below Lancaster, Herring Gulls are perhaps more frequently observed than elsewhere in Pennsylvania, ex- cept in the vicinity of Erie city. The Herring Gull is not especially an arctic breeder. It nests, ac cording to different writers, along the coast and about lakes of the inte- rior in the New England states, and also from Lake Superior northward to the Arctic shores. This species breeds generally on the ground, though sometimes high and inaccessible cliffs are selected as breeding places, and occasionally in some localities, particularly in regions where the natives collect both the eggs and young for food, they frequently, to escape such depredations, build their nests in the tops of high trees. Mr. George Spencer Morris, of Philadelphia, informs me he has observed both Herring and King-billed Gulls, as winter visitants, on the Dela- ware river, near the city. Larus delawarensis ORD.

DESCRIPTION. 11 Adult.— Head, neck, under parts and tail pure white ; back and wings very light pearl blue ; first and second primaries black for two-thirds of their length towards the end, the three next quills have the black much less in extent, and on the sixth it is reduced to a sub-terminal bar ; the first quill is black at the end, above which is a broad white band ; the second quill is black to the tip, with a white spot on the inner web an inch and a half from the end ; the other primaries tipped with white ; secondaries and tertiaries ending in white ; iris yellow ; bill crossed near the end 7/ith a blackish-brown band, between which and the base it is greenish-yellow ; the tip is yellow ; tarsi and feet greenish-yellow. Length about 20 inches ; extent about 48 inches. BIRDS OF PENNSYLVANIA. 15 " Young. — The upper plumage mottled with blackish-brown and gray ; beneath grayish-white, with light-brown spots ; primaries black ; tail white, with a sub- terminal black band ; bill black with yellow base."— Baird's Birds of N. A. Habitat.— North America at large ; south in winter to Cuba and Mexico. This species occurs in Pennsylvania during- the spring- and fall migra- tions, but is not common. Specimens have been taken on the Dela- ware, Susquehanna, Allegheny and Ohio rivers in this state, and also at Lake Erie, near the city of Erie. Unlike most of its relatives, this Gull breeds in many sections of the United States, as well as far northward. This is one of the common Gulls to be seen, in winter, on the Atlantic coast from New Jersey southward. Larus atricilla LINN. Laughing Gull. DESCRIPTION. Adult, in breeding plumage. — Head and upper part of neck dark slate color, dark- est about occiput and on neck, and lightest about base of bill ; the dark color ex- tends about one inch or more farther down front of neck than on the back of same ; white spot on both upper and lower eyelids ; neck all round, breast, abdomen, sides, lining of wings, upper and lower tail coverts, rump and tail pure white ; the breast and abdomen in recently-killed specimens have a beautiful rosy tinge ; mantle dark lead color ; first five primaries black, which decreases from first to fifth. In speci- men before me all the primaries but first and second are tipped with white ; the sec- ondaries and tertiaries have broad white tips ; bill (dried specimen) dark carmine and somewhat yellow at base ; tarsi yellowish-red ; iris bluish-black. , Adult, in winter. — Head and neck white, with sides and occiput spotted with brownish-gray. Young.— Head, neck all round and upper parts brownish-gray, darkest at base of head ; mandible similar color but darker ; throat and under parts grayish or dull white. Length about 16| inches ; extent about 40 inches. Ha bit a t.— Eastern, tropical and warm-temperate America, chiefly along the sea- coast from Maine to Brazil ; Pacific coast of middle America. The Laughing Gull is so named because its notes resemble a loud burst of laughter. In this state the bird is found only as a migrant. In the spring individuals of this species frequently ascend the Susque- hanna river as far as Harrisburg- ; they also sometimes come up the Delaware river to Philadelphia, and occasionally are observed on other of our larger streams in the eastern part of the state. In the autumn the Laughing Gull is rarely, I think, to be found in Pennsylvania. The Black-headed Gull, as this species is sometimes called, is not found on the Pacific coast of the United States, but is quite common on the At- lantic side, especially from New Jersey southward. The nest — built on the ground — is composed of sea-weed, grass or other veg-etable mate- rials. The eggs, two or three in number, measure about 2.20 inches in length by about 1.58 inches in width ; they vary considerably, but usu- ally the ground color is grayish or brownish-olive, spotted and blotched with different shades of dull reddish-brown and black or purplish ; the markings are often more abundant about the larger end. The eggs of 16 BIRDS OF PENNSYLVANIA. this species are used in many sections along the Atlantic coast, especi- ally in some of the southern states, for table purposes. Larus Philadelphia (ORD.). Bonaparte's Gull; " Little Gull." DESCRIPTION (Plate 52). Adult.— Bill, black ; tarsi (dried skin), reddish-yellow ; head and upper part of neck dark lead color ; lower part of neck, under parts, rump and tail pure white ; mantle, pale pearl-blue ; three first primaries mainly white ; first primary with black outer web ; first six primaries have black ends, a half inch or over long and each one is slightly tipped with white ; other primaries like back. In winter the adult has white head with dark spots over ears, in other respects quite like adult in spring. Young.— Bill, black, yellowish at base ; tarsi, reddish-yellow (dried skin) ; iris, hazel ; greater part of head, the throat, neck and under parts white ; tail, white, except a black bar nearly an inch wide at end ; primaries with much more black than in adult ; dark colored auricular spots ; crown and upper parts, espe- pecially the wings, mottled with light lead color and brownish-gray ; length about 14 inches' ; extent about 32 inches. Habitat— Whole of North America, breeding mostly north of the United States ; south in winter to Mexico and Central America. \ This species known to fishermen on Lake Erie and about the Dela- ware and Susquehanna rivers as " Little Gull," is by far the most abun- dant of all the Gulls in Pennsylvania, where it occurs as a regular mi- grant in the spring- and fall. During- migrations, particularly in the autumn, these birds are frequently to be seen in considerable numbers about the harbor at Erie city. Bonaparte's Gulls are found generally throughout the state, about the numerous lakes, ponds and larger streams. Occasionally in the interior good-sized flocks are noted, but usually they are seen singly, in pairs, or sometimes in small parties of four or five individuals. They generally arrive here early in April and remain mostly until early in May, when they pass northward to their breeding grounds, from which they -return here usually about the first week in October and remain until early in November. At Lake Erie, where the species is perhaps more numerous than in any other section of Pennsylvania, I observed a flock of a dozen or more of these Gulls in company with two or three Herring Gulls late in the month of Decem- ber, 1889. This bird, in addition to feeding on fish and other kinds of aquatic animal life, subsists, also, to a considerable extent, on different insects, particularly beetles and grasshoppers. GENUS RISSA STEPHENS. Rissa tridactyla (LINN.). Kittiwakc. DESCRIPTION. " Adult.— Head, neck, entire under plumage, rump and tail, white ; back and wings light bluish-gray ; the ends of the five outer primaries, and the outer web of the first, black; the fourth and fifth have small white tips; bill, greenish -yel low »' iris, reddish-brown ; legs and feet brownish-black, with a green tinge.

A. Length about 17| inches ; extent about 35 inches. Habitat.— Arctic regions, south in eastern North America in winter to the great lakes and the Middle States. Accidental winter visitant. About ten years ago the late Henry B. Graves, of Berks county, mounted a young Kittiwake, which had been captured near Lancaster city in midwinter. Mr. Joseph Krider, of Philadelphia, has in his collection one of these birds which was shot several years ago near Philadelphia by the late John Krider. Dr. A. C. Treichler, of Elizabethtown, mentions this species as a straggler in Lancaster county, Pa. The Kittiwake is a common bird in the arctic regions, and in winter this species wanders irregularly southward along the Atlantic coast as far as New Jersey, where it is quite rare. SUBFAMILY STERNIN^B. TERNS. THE TERNS. While these birds are most abundant on the seacoast, neighboring bays and inlets, they are not exclusively maritime ; many frequent, during migrations, inland waters (large lakes commonly) where some also remain during the summer to rear their young. None of the Terns are known to breed in Pennsylvania. Although quite a number of these birds — known commonly about the seashore as "Sea Swallows" — have been taken by various naturalists and collectors, in this state, during migrations, none, according to my observations, can be said to occur through- out this comm'onwealth as regular or common spring and fall migrants. Several species are common on the coast of New Jersey during migrations, and some are also found there as summer residents. Almost every year, in the spring, late sum- mer and in the autumn, after severe stormy weather, Terns of different kind are frequently noticed about the rivers, lakes and ponds in the interior, principally, however, in the eastern sections of the state. These birds, it would appear, have been, by force of the elements rather than their own inclinations, compelled to leave, temporarily, their chosen haunts in the vicinity of the ocean. At Lake Erie, some species of this subfamily are found as common migrants ; in the harbor at Erie city two or three species are more or less common every spring and fall. This is the only section in Pennsylvania, so far as I have been able to learn, where Terns are seen with any degree of certainty during migrations. Terns, with a few exceptions, are much smaller than Gulls, from which they differ also in having straight, slender, sharp-pointed bills, and, mostly, conspicuously forked tails. The sexes are quite similar in size and color, but the young and old birds in fall and winter show great variations in coloration ; wings long, narrow and pointed ; the flight is buoyant and graceful. They seem to be almost continually on the wing, and sometimes are seen out at sea many miles from land. Terns are unable to dive ; their feet are webbed, but they are scarcely ever seen on the water ; it is said they never swim from choice. These birds walk but little, though they often alight on the beach, sand-bars and rocks. Terns, especially the larger kinds, subsist princi- pally on little fish ; some of the smaller species, in addition to small fish, feed to some extent on insects. When in quest of prey they frequently make extensive circuits over the ocean, bays, brackish ponds and marshy places ; in flying over the water, searching for food, they invariably are seen with the bill pointing straight down- ward ; this, as Dr. Coues writes, " makes them look like colossal mosquitoes." They 2 BIRDS. 18 BIRDS OF PENNSYLVANIA, often hover over the water, when feeding, in the same manner as the Sparrow Hawk does when hunting in a grass-field, and dart head foremost into it, oftentimes with such force as to submerge the whole body ; unlike the hawk, however, which seizes his prey in his talons, the Tern captures its prey in its bill. Their notes are sharp, shrill and often repeated ; they are particularly noisy when wounded or if their breeding-places are approached. The eggs, two or three in number, are generally deposited in a slight depression in the sand or shingle along the sea-beach ; some few nest on drift-stuff, sea-weeds, grasses, etc., in marshes, and others, it is stated, construct rude and rather bulky nests of sticks on trees or in low, thick bushes. Terns are of a gregarious nature ; they frequently nest in great numbers in suitable localities, and when migrating they often assemble in large flocks. Great numbers of these birds, and many of the smaller kinds of Gulls, are annually slaughtered along the Atlantic coast by heartless and greedy "feather hunters" to supply the millinery establishments of our large cities. GENUS GELOCHELIDON BREHM. Gelochelidon nilotica (HASSELQ.). Gull-billed Tern ; Marsh Tern. DESCRIPTION. Adult. — Bill short, stout and resembles somewhat that ot a gull ; top of head black, which runs downward on sides to lower eyelid ; a very narrow line of white at base of upper mandible ; back and wings pearly bluish-gray ; tail feathers very similar to back, but lighter ; lower part of back of neck and entire under plumage pure white ; bill and tarsi black ; iris dark brown. Length about 14 inches ; extent about 3* inches. The young have brownish-colored bills and legs, top of head largely white ; upper parts more or less spotted with brown. H'lbita .— Nearly cosmopolitan ; in North America cbiefly along the Atlantic and Gulf coasts of the United States. This species is a very rare and irregular visitor in eastern Pennsyl- vania, and in the central and western portions of the state I find no one has noted its occurrence. Mr. H. B. Graves records the capture of one "in Chester county in autumn." Mr. C. D. Wood informed me he ob- tained two specimens, which were shot near Philadelphia about five years a^o. I have never seen this bird in Pennsylvania. GENUS STERNA LINNAEUS. Sterna tschegrava LEPECH. Caspian Tern. DESCRIPTION. Largest of all the Terns ; bill large and stout, measuring about three inches ; tail very slightly forked. " Adult.— Forehead, crown, sides of the head and occiput black, glossed with green ; this color extends below the eye, under which is a narrow white line ; back and wings light bluish-ash ; outer six primaries dark slate-gray on their inner webs ; quill shafts strong and white ; tail and its upper coverts grayish-white ; neck and entire under plumage pure white ; bill and inside of mouth bright vermillion • legs •I BIRDS OF PENNSYLVANIA. 19 and feet black. Length 21^ inches; extent of wings 51 inches."— Baird's Birds of North America. Habitat.— Nearly cosmopolitan ; in North America breeding southward to Vir- ginia, Lake Michigan, Texas, Nevada, California. The Caspian Tern has been observed in but few localities in this state. Hon. J. J. Libhart, in his ornithological report, published in the history of Lancaster county, Pa., records the capture of two of these birds : In both cases the van is led by an old gander, who, every now and then, pipes his well known honk, as if to ask how they come on ; and the honk of 'All's well ' is generally returned by some of the party. Their course is in a straight line, with the exception of the undulations of their flight. When bewildered in foggy weather, they appear sometimes to be in great distress, flying about in an irregular manner, and for a considerable time over the same quarter, making a great clamor. On these occasions, should they ap- proach the earth and alight — which they sometimes do to rest and rec- ollect themselves — the only hospitality they meet with is death and de- struction from a whole neighborhood already in arms for their ruin." The food of this species consists chiefly of vegetable materials, such as cereals, the seeds, roots and other portions of plants. BIRDS OF PENNSYLVANIA. 51 Branta bernicla (LiNN.). Brant. DESCRIPTION. Bill rather small and short Bill and legs black ; iris brown. Head, neck, body in front of wings, primaries and tail black ; a small white patch on each side of neck streaked with black ; few white feathers on chin and about lower eyelids ; back brownish-gray, lower parts quite similar but lighter ; rump darker than upper part of back ; feathers about tail mostly white. Length about 23 inches ; extent about 46 inches. Habitat. — Northern parts of the Northern Hemisphere ; in North America chiefly on the Atlantic coast ; rare in the interior, or away from salt water. The Brant, or Brant Goose, as this species is usually called by sports- men, is found in Pennsylvania only as a very rare and irregular visitor, about our large rivers. In January, 1890, 1 purchased one of these birds from a gunner who had shot it on the Susquehanna river near Harris- burg, Pa. Mr. D. Frank Keller of Reading, Pa., has a specimen which was captured in Berks county ; and Dr. G. A. Scroggs, of Beaver, Pa., informs me Brant geese are occasionally found on the Ohio river, in Beaver county. The Brant feeds almost exclusively on a vegetable diet. SUBFAMILY CYGNIN^. SWANS. GENUS OLOR WAGLER. Olor columbianus (ORD.). Whistling Swan. DESCRIPTION. Neck longer than body. Length about 4£ feet ; extent about 7 feet ; bill has yellowish spot in front of eye, rest of bill, also legs and feet black ; eyes brown. Plumage of adult is pure white, with the head, neck and belly in some individuals tinged with rusty. The young are said to be a light lead color, with head and neck tinged with yellowish- brown ; and the color of legs, bill and feet is described as being much paler. Habitat.— Whole of North America, breeding far north. Spring and fall migrant, also occasional winter visitant. This species is more frequently seen on Lake Erie and about our principal rivers than elsewhere, though it occurs generally throughout the state. The following interesting account * of an unusual flight of these swans, is from the pen of my friend, Mr. Geo. B. Sennett, of Erie city, Pa.: " An unusual flight of swans occurred in northwestern Pennsylvania on the 22d of last March (1879). Crawford, Mercer, Venango and Warren counties being the places where they were seen. On the day mentioned, as well as the previous day and night, a severe storm pre- vailed, the rain and snow freezing as they fell. The swans, on their migration north, were caught in the storm, and becoming overweighted * Bulletin Nutt. Club. Vol. V. pp. 125, 126. 52 BIRDS OF PENNSYLVANIA. with ice soon grew so exhausted that they settled into the nearest ponds and streams almost helpless. Generally a single one was seen in some mill-pond or creek, and the fowling-piece loaded with large shot, and not unfrequently the rifle, was used to bring- to bag- the noble game, though, considering the plight they were in, in all probability any one might have paddled up to the birds and taken them alive. In fact in a number of instances they were reported as thus taken alive. Large flocks were seen in some districts in the same pitiable condition. In close vicinity of Meadville only two, I believe, were taken. Titusville and Oil City and the intervening eighteen miles up Oil creek and its branches seem to have been the points where they were seen in greatest number. A published report from the former place states that ' ten or twelve White Swans were captured alive ' near East Titusville. The report from the Bouseville (three miles above Oil City, on Cherry run) correspondent of the Oil City Derrick states : ' A flock of from thirty- three to thirty-five American or Whistling Swans surprised the inhabi- tants of Plumer on Saturday forenoon by alighting in the waters of Cherry run. One of the swans was almost immediately shot at and killed, and, to the surprise of the now large crowd of men and boys, the remainder of the flock, on account of the ice accumulating on their wings, was unable to fly, and a general rush was then made for the poor birds, and twenty-five were captured alive by the eager fellows. Some have them yet alive, but many were killed for their feathers and flesh. The remaining eight or ten birds finally managed with great difficulty to arise. One, however, soon alighting in the midst of Bouseville village in Cherry run, was soon killed by Dave Phillips, the balance flying a little further, alighting in Oil creek. A general stampede of men and boys now took place, the greater part armed with some weapon of war- fare ; but Charley Clark, a noted sportsman and accurate shot, led the van, and was successful in laying over two of the splendid birds, and badly wounding a third, at the first shot. He afterward shot the third and fourth, and the vociferous crowd returned to town, four men bearing the burdens of the victor's spoils. The larger of the birds shot by Clark was a magnificent creature, measuring fifty-one inches from tip of bill to tail, and eighty-six inches in extent, and weighing over sixteen pounds ; it is said that the one shot by Phillips was larger, weighing- twenty pounds."

Sexes alike in plumage. Male.— Bill (dried skin) both mandibles about base blackish ; most of lower man- dible, sides of maxilla in front of nostrils and culmen, of brownish-yellow ; lightest on upper surface ; bare skin of head and upper part of neck dull bluish-black, thickly covered, especially on nape and back of neck, with grayish-brown scales ; tail and long wing feathers black, with green, purplish and bronze reflections. Rest of plumage pure white ; legs (dried skin) brownish-black ; toes yellowish ; iris dark-brown. Length about 4 feet ; extent about 5£ feet. Weight 9 to 12 pounds. Habitat.— Southern United States, from the Ohio Valley, Colorado, Utah, Califor- nia, etc., south to Buenos Ayres ; casually northward to Pennsylvania and New York. The Wood Ibis, a common resident in the southern states, occurs in Pennsylvania as a very rare and irregular visitor. The late Judge Lib- bart, in his ornithological report of Lancaster county, says : " I ob- tained a fine specimen of this species, shot from a troop of ten by Mr. M. Ely on the Susquehanna, July, 1862." Mr. C. J. Pennock, in his catalogue of Chester county birds, writes that a Wood Ibis was taken a number of years ago by the late Vincent Barnard. Prof. August Kock, of Williamsport, has one in his collection which was captured a few years ago in Lycoming county, and Dr. Walter Van Fleet, of Eenovo, includes it among the stragglers in his list of species found in Clinton county. Dr. A. C. Treichler, Elizabeth- town, has specimens of this bird in his collection which were shot in Lancaster county in the early part of July, 1883, shortly after severe storms. Mr. Geo. P. Friant, of Scranton, informs me that a small flock of Wood Ibises, about four or five years ago, were seen in his neighbor- hood. In Florida, where these birds were very common in 1885, 1 found they fed chiefly on fish, frogs and snakes. NOTE. — Dr. Turnbull (Birds of Eastern Pennsylvania) writing of the Glossy Ibis (Plegadis autumnalis) — family Ibididce, says : " Last season (1866) Mr. John J£rider shot a specimen just below Philadelphia. At long intervals it has been seen on the river Delaware." I have in my 54 BIRDS OF PENNSYLVANIA. possession a specimen of the White Ibis (Guara alba) — family Ibididcn, which is said to have been captured in Pennsylvania about thirty years ag-o. In the museum at Lancaster city, there is a specimen of the Roseate Spoonbill (Ajaja ajajd) — family Plataleidce, which it is stated was captured over twenty-five years ago in Lancaster county. As none of these three species have, so far as I can learn, been observed in Penn- sylvania during the past quarter of a century, I do not consider that any of them are entitled to a place in this report. SUBORDER HERODIL HERONS, EGRETS, BITTERNS, ETC. FAMILY ARDEID^E. HERONS, BITTERNS, EGRETS. THE HERONS, ETC. Birds oi this family— containing, it is said, about seventy-five species— are very generally dispersed throughout all parts of the globe. A few species wander to cold countries, but the great majority of these waders inhabit the lower temperate and tropical regions. In different localities throughout the United States, about fifteen species and varieties (local or geographical races) are recorded by modern writers ; of these nine species have been taken, during recent years, in Pennsylvania. Some species occur with us as regular summer residents, while others are observed here only as transitory visitors in the spring and fall migrations. These birds frequent muddy banks of rivers, creeks, lakes and ponds ; they are also found about swampy meadows and marshy places, particularly if the latter are well supplied with pools of shallow water, protected by trees or bushes. They often remain quiet or inactive in daytime, but as evening approaches, or in the night, they go out, like the owls, in quest of food, which is secured by rapid, dexterous thrusts of their long, spear- like bills. Birds of this group subsist chiefly on various kinds of fishes (fish meas- uring nearly a foot in length are often swallowed by large herons), frogs and snakes ; and they also eat other kinds of animal food, such as large insects, field-mice, lizards, cray-fish, leeches, etc., and some of the larger herons occasionally catch wood-rats, and young birds of other species which breed about their favorite feeding resorts With the exception of the Bitterns, these birds are gregarious, particularly when breeding, and in the southern states where herons and egrets are abundant, they often breed together in great numbers, frequently in company with cormorants, water turkeys and ibises. The herons and egrets build rude and bulky nests of sticks and twigs, in trees or bushes ; the bluish or greenish colored and unspotted eggs vary from two to six in number. The sharp, rasping cries of these birds, are often uttered when feeding, also if they are frightened, and frequently when flying, either when migrating or when going to and from their feeding places. Birds of this family are known by the following characters : Long neck and legs ; bill long, straight, tapering, acute and furnished with sharp cutting edges. Lores naked and usually, particularly in the breeding season, bright colored ; the head is rather long, narrow and flat on the sides. When breeding these birds frequently have back of head, the lower neck, back or scapulars, beautifully ornamented with long plumes. Herons and egrets have three pairs of powder-down tracts, one on lower part of back, the second on lower belly, and a third on breast. Bitterns have two pairs of these tracts, one on lower back, the other on breast ; toes long and slender ; the claws are long and curved, especially that of hind toe, and the middle claw has a fine comb on inner edge. The hind toe is inserted on a level with three in front ; outer toes usually connected with middle by a small web at base, others free. Tail very short, twelve feathers, except in bitterns, which have only ten. - a* if ^ BIRDS OF PENNSYLVANIA. 55 SUBFAMILY BOTAURIN-ffi. BITTERNS. GENUS BOTAURUS HERMANN. Botaurus lentiginosus (MONTAG.). American Bittern ; Indian Hen. DESCRIPTION (Plate 5) . Adult.— Bill yellowish, dusky on ridge, lores greenish yellow ; legs and feet yel- lowish-green ; iris yellow. Length, about 26 inches ; extent, about 45 inches. Gen- eral color brownish-yellow, top of head dull brown, upper parts finely freckled and variegated with different shades of brown, blackish and whitish ; chin and throat white with brown streak ; a broad and glossy-black stripe about three inches long on upper part of neck. Habitat.— Temperate North America, south to Guatemala and the West Indies. The Bittern or " Green-legged Crane," as this wader is called by many sportsmen, is readily distinguished from other birds of the family by its brownish-yellow plumage, greenish-colored legs, and large size. It is a summer resident in Pennsylvania, where it arrives generally early in April and remains until about the first week in November. Although these birds breed, occasionally at least, in different parts of the state, they are much more frequently met with (singly or in pairs) when mi- grating in the spring and fall, than in summer. In this locality these birds are never found in flocks ; commonly only solitary individuals are seen frequenting chiefly the thick swampy districts about meadows and rivers. During the daylight Bitterns conceal themselves in the long grasses, weeds, bushes, etc., growing about swamps. They migrate and feed during the night. Mr. George B. Sennett, Erie, Pa., says, he is quite certain this species breeds occasionally on the peninsula, near Erie city ; also at Conneaut Lake, Lake Pleasant and Oil Creek Lake, in Crawford county. Mr. W. H. Buller, residing at Marietta, Lancaster county, Pa., in a letter dated July 29, 1889, addressed to me, writes as follows : " I am inclined to believe that the American Bittern breeds in the vicinity of Schock's Mills, a few miles west of Marietta. While I have never found its nest or seen its young, yet I have so frequently seen the bird in that vicinity during the summer that I think it probable that it breeds in the swamps there." Dr. George B. Boss, of Lebanon, Pa., states that it breeds in Lebanon county. In Perry county, Mr. H. Justin Boddy, Millersville, Pa., has observed it as a " rare breeder." Mr. J. F. Kocher, of South Whitehall, Pa., says the Bittern is occasionally found breeding in Le- high county, and Dr. Walter Van Fleet of Benovo, Pa., mentions it as breeding occasionally and sparingly in Clinton county. The nest of this bird is placed on the ground ; the eggs, three to five in number — three is said to be the usual number — are described as brownish-drab, unspotted, measuring about 2 inches long by about If inches broad. 56 BIRDS OF PENNSYLVANIA. According to Dr. Coues, " the food of this bird consists of various kinds of small aquatic animals. In its stomach may be found different molluscs, craw-fish, frogs, lizards, small snakes and fishes, as well as insects. Such prey is captured with great address, by spearing, as the bird walks or wades stealthily along. The thrust of the bill is marvel- ously quick and skilful — more action is displayed on such occasions than probably under any other circumstance." — Birds of the Northivest. Although Bitterns frequently devour fish, I believe they prefer other kinds of animal food, especially snakes, frogs and insects. The food materials of nine of these birds, which I have examined, are given in the following table : No. DATE. LOCALITY. FOOD-MATERIALS. 1 April 11. 1880, . Chester county. Pa. . . .

Habitat.— Temperate North America, from British Provinces to the West Indies and Brazil. The Least Bittern, the smallest of the herons, I have found in this state only as a rather rare visitant during the spring and fall migrations. This species is sometimes, though rarely, observed in Pennsylvania during the breeding season. When alarmed they fly generally but a few yards and take shelter among the reeds or long grass. Least Bitterns are scarcely ever seen exposed, but skulk during the day, and, like the preceding species, feed chiefly in the night. Mr. Geo. B. Sennett, of Erie, has taken specimens in Crawford and Erie counties, where it is said the species breeds occasionally. Dr. John W. Detwiller, of Bethlehem, Pa., has found the Least and also the American Bitterns breeding here. From personal observation I know nothing concerning the nest or eggs of this species. The following in- teresting remarks relating to nest and eggs of this bird are taken from Oliver Davie's valuable work (Nests and Eggs of North American Plate 13. Marsh Hawk. 1, Male; 2. Female. BIRDS OF PENNSYLVANIA. 57 Birds}: "In some places as many as a dozen or twenty pairs breed along the grassy shores of a small lake or pond. Like the last, it in- habits reedy swamps and marshes where the quagmire abounds with a luxuriant growth of rushes, which is also the home of the rails. The nest is placed on the ground or in the midst of the rankest grass, or in a bush. It is often placed on floating bog, and is simply a platform of dead rushes. The bird has many odd habits. When standing, on the edge of a stream, with its neck drawn in, it is often taken for a wood- cock, the long bill giving it this appearance. It appears so stupid at times that it may be caught with the hand. The bird is mostly seen just before or after sunset. In many of the southern states this species rears two broods in a season, fresh eggs having been obtained in May and August. In Texas, Mr. Rachford says, it nests along the edges of the water courses in May, bending down the tops of water grass and platting it into a snug little nest, about two or three feet above the water. * * * * The eggs of the Least Bittern are from three to five, usually four, in number, pale bluish or greenish-white, elliptical in shape. The average size is 1.20 by .93." According to Nuttall, this species subsists chiefly on small fish and aquatic insects. Audubon states that "the food of this bird consists of snails, slugs, tadpoles, or young frogs and water-lizards. In several instances, however, I have found small shrews and field-mice in their stomachs."

Adult. — Bill about six inches long, chiefly yellow, dusky on culmen ; eyes yellow ; legs and feet blackish, yellowish about toes ; lores greenish-yellow or bluish. The color of bill, legs and lores vary greatly not only with age and season but also with individuals. The male, larger than female, is about 4 feet long and about, six feet from tip to tip. Forehead and central portion of crown white, surrounded on sides and behind with black ; long occipital feathers black ; neck chiefly brownish-gray : feathers on middle (in front) of lower two-thirds of neck, with a showy streak of 58 BIRDS OF PENNSYLVANIA. black, white and rusty ; chin and upper part of neck in front white. Tibise and edge of wing reddish-brown ; upper parts and tail light bluish-slate color ; long scapular feathers and long loose feathers on lower neck ; crissum white ; under parts chiefly black, streaked with white. The young are different in many respects from the above, but can always be known by their large size and a general resemblance to the adult. Habitat. — North America, from the Arctic regions southward to the West Indies and northern South America. This bird, the largest of our herons, is a summer resident in various localities in this state. During- the last few years, however, several favorite breeding1 resorts in eastern Pennsylvania, which were annually visited by this and other species, have been broken up by boys and men who destroyed the birds, old and young, simply because their feathers would bring a few dollars, and, as they remarked, " there's no law to stop it." I have no doubt that the time will soon come when this beautiful heron will be known in this commonwealth only as a rare straggling visitant. The nest is made of large sticks and twigs, and placed on the larger limbs of trees, generally near the water. The eggs vary in num- ber from three to five, are light-blue in color, and about the size of those of our common domestic fowl. This bird, and the same is true of other herons, when wounded and unable to escape, is one which cannot be handled with too much caution, as it frequently, with its sharp and powerful bill, inflicts severe, dangerous, and, it is said, sometimes fatal wounds. In Florida I met a hunter who had an eye destroyed by one of these birds which he had winged and carelessly attempted to pick up. By some, particularly residents of certain of the southern states, the flesh of the Great Blue Heron is considered quite a delicious morsel. Some few winters ago, when camping in the cypress swamps of Florida, I, more from necessity than choice, eat the breast meat of this heron and also that of the Water Turkey (Anhinga anhinga), a bird which preys exclusively on fish, and although I did not especially relish the dish, I must admit that to a hungry man it was in no way disagreeable. The following interesting observations on the food-habits are given by Nuttall : " Fish is the principal food of the Great Heron, and for this purpose, like an experienced angler, he often waits for that condition of the tide which best suits his experience and instinct. At such times they are seen slowly sailing out from their inland breeding haunts, dur- ing the most silent and cool period of the summer's day, selecting usually such shallow inlets as the ebbing tide leaves bare or accessible to his watchful and patient mode of prowling ; here wading to the knees he stands motionless amidst the timorous fry, till some victim coming within the compass of his wily range is as instantly seized by the pow- erful bill of the heron. * * * If large the fish is beaten to death, and commonly swallowed with the head descending, as if to avoid any obstacle arising from the reversion of the fins or any hard external BIRDS OF PENNSYLVANIA. 59 processes. On land our heron has also his fare, as he is no less a suc- cessful angler than a mouser, and renders an important service to the farmer in the destruction he makes among most of the reptiles and meadow shrews. Grasshoppers, other large insects, and particularly dragon-flies, he is very expert in striking, and occasionally feeds upon the seeds of pond lilies, contiguous to his usual haunts. Our species, in all probability, as well as the European Heron, at times preys upon the young birds which may be accidentally straggling near their soli- tary retreats." In the months of March and April, 1885, 1 examined the stomachs of twenty-three of these birds which had been killed by plume-hunters in Orange and Volusia counties, Florida. Twelve birds had fed entirely on fish ; three had taken fish and cray-fish ; two, small snakes ; one, frogs and fish; one, fish and a few feathers; one, traces of beetles, Three birds were destitute of all food materials. From my investigations made in Florida, as well as the records in the following table, I would say this heron is mainly piscivorous in habit : No. DATE. LOCALITY.

The plumage of this bird is entirely white ; in the breeding season the adults have the backs ornamented with long hair-like plumes, frequently so long that they touch the ground when the bird stands erect ; legs and feet black ; eyes bright yel- low ; bill yellow, and about five inches long ; point of upper mandible black ; meas- ures, from tip to tip of wings, about five feet Habitat.— Temperate and tropical America, from New Jersey, Minnesota and Oregon south to Patagonia ; casually on the Atlantic coast to Nova Scotia. This beautiful bird, now chiefly found in the southern states, where it is rapidly being exterminated by the heartless and money-loving plume-hunters, is a rather rare and irregular migrant in Pennsylvania. It occurs in this state, generally, only in the late summer and autumn, when straggling individuals are seen in suitable locations, in almost every quarter of the commonwealth. In former years, this species is said to have reared its young in Pennsylvania. The stomach contents of thirteen of these egrets, which I have examined, are here given • 60 BIRDS OF PENNSYLVANIA.

Adults in the breeding season have long fine hair-like occipital feathers ; the long plumes on back are frequently curved upward at ends, which reach to or a little beyond the ends of tail ; plumes on lower neck similar but not curved. Plumage in both sexes, and at all ages, entirely white ; bill black, yellow at base ; lores, eyes and posterior part of tarsus, yellow, rest of legs black ; length about 24 inches ; ex- tent about 38 inches. In young birds the occipital feathers are slightly developed, and they also lack the long plumes of back, and jugulum. Old birds when not in breeding dress, have generally at all seasons, the occipital crests well developed, but lack the hair-like plumes on back and lower neck. Habitat.— Temperate and tropical America, from Long Island and Oregon south to Buenos Ayres ; casual on the Atlantic coast to Nova Scotia. This beautiful heron is most plentiful in the southern states, where it breeds in company with other species. Solitary individuals are sometimes found in this locality during" the late summer or early autumn. This egret is much less frequently met with in Pennsylvania than the last. In the counties of Crawford and Erie, Messrs. Geo. B. Sennett, of Erie city, and H. C. Kirkpatrick, of Meadville, have found the Snowy Heron only as a very rare and irregular visitor. Prof. H. Justin Roddy, writing to me July 29, 1887, from Landisburg, Perry county, says, " July 27th I secured here a very fine specimen of the American Egret (A. egretta); the first I have ever seen in this county. I have a number of times seen the Snowy Heron (A. candidissima) in this locality." Occasional stragglers of this species have been met with in Lehigh and Northampton counties, by Dr. John W. Detwiller, of Bethlehem. Mr. J. F. Kocher, of South Whitehall, Lehigh county ; Dr. Geo. B. Boss, of Lebanon, Lebanon county ; Dr. Walter Van Fleet, Benovo, Clinton county; Jonas Stern, Kutztown; D. Frank Keller, Beading, Berks county ; George Miller and Casper Loucks, York, York county ; Dr. A. C. Treichler, Lancaster county ; M. J. Webster, Madi- sonville, Lackawanna county, and Dr. I. F. Everhart, of Scranton, Lacka- wanna county, all report this heron in their respective counties as a rare and irregular straggler. Nuttall says: "Its food, as usual, consists of small crabs, worms, Plate 14. Sharp-shinned Hawk. 1. Male; 2. Female. BIRDS OF PENNSYLVANIA. 61 snails, frogs and lizards, to which fare it also adds at times the seeds of the pond lilies and other aquatic plants." In April, 1885, 1 visited an island in a small lake in Orange county, Florida, where this species, also the Louisiana, Little Blue, and Green Herons, were breeding on low bushes. I shot seven Snowy Herons, and found in the viscera of all only the remains of fish. Ardea tricolor ruficollis (GossE.). Louisiana Heron. DESCRIPTION. Adult in breeding season. — Bill four inches or a little more in length, and very slender. Bill (dried skin) bluish-black, and yellowish about base ; lores and naked skin around eyes yellowish ; eyes reddish-yellow ; legs dusky bluish-yellow. The three or four longer occipital plumes, lower part of back, rump, sides, under parts generally, edge of wing, axillars, lining of wings, chin and upper part of throat, white ; front and top of head, sides of same, malar region, and most of feathers on sides of long neck, bluish-slate color; upper tail coverts white and bluish ; greater part of crest, lower portion and back of neck reddish-purple. Long fine scapular plumes, light brownish gray, quite pale at ends ; the white throat is continuous with a reddish-brown streak (brightest on upper third of neck) which narrows and be- comes less distinct, as it extends down in front. The young are never white as in Ardea cosrulea : they lack the long occipital plumes, also the fine scapular feathers ; the head and neck light brownish-red ; chin, throat and malar region white ; neck in front streaked with white and brownish. Length about 27 inches; extent about 36 inches. Habitat. — Gulf states, Mexico, Central America and West Indies, casually north- ward to New Jersey and Indiana. The Louisiana Heron, more or less abundant in many of the south Atlantic and gulf states, I have never seen in Pennsylvania, where it has been observed only as a rare or accidental visitor in the late summer or autumn. Stragglers have been seen, at irregular intervals, by the following named gentlemen in their respective localities : Dr. John W. Detwiller, Bethlehem,Northainpton county ; D.Frank Keller, Beading, Berks county, and Dr. W. Yan Fleet, Benovo, Clinton county. This handsome bird, and one which is particularly graceful in its movements, I found breeding in company with other species on low bushes in Florida, in March and April, 1885. Their rather flat nests were made entirely of small sticks. The bluish-green eggs, three to five in number, measure about 1.75 inches long and a little more than 1.25 inches broad. The viscera of eleven of these birds, which were killed at this nesting place, contained fish, frogs and snails. 62 BIRDS OF PENNSYLVANIA. Ardea coerulea LINN. Little Blue Heron ; Little White Heron. DESCRIPTION.* Bill about three inches long, and quite slender. Adult (blue phase), breeding plumage. — Bill and lores bluish, former black to- wards end ; the long, narrow and pointed dorsal plumes extend sometimes several inches beyond the tail ; legs and feet black ; eyes yellow ; head and neck "purplisn- red or maroon colored," top of head and fine hair-like crest, bluish with purplish reflections ; lower part of neck and rest of plumage slate-blue (quite light in some birds and dark in others) ; some specimens have sooty-black streaks or patches on back and most of belly. In fifteen of these herons I find ten have a blue streak more or less complete extending down front of neck ; one has throat bluish and white ; theother four have necks without these streaks, and as previously described Adult (blue and white or intermediate phase). — Four birds show about the fol- lowing coloration : Top of head, most of occipital crest, patches on the sides and back of neck, most of the forepart of back (usually rather continuous on back), tips of primaries, some of long neck plumes, also a few of the long dorsal plumes, different shades of bluish ; remainder of plumage white ; bill chiefly bluish black (one has yellowish streak on maxilla) ; bluish-yellow about lores and eyes ; legs bluish-black ; eyes yellowish. One bird has greater part of back, several large wing feathers, and a number oi the long dorsal plumes which extend beyond the tail, entirely slaty- blue ; primaries faintly tipped with dusky-blue ; the top of head and occipital crest, light blue ; single maroon feathers, small patches of a like color appear on head and neck. Adult (white phase).— Two birds : Bill, lores and legs (dried skin) bluish-black ; eye.s yellow ; ends of outer quills bluish ; top of head and parts of neck with a faint bluish tint ; rest of plumage pure white. Young. — Bill greenish yellow from base to about half its length ; under surface of lower mandible yellowish, rest of both mandibles blackish ; lores greenish-blue ; eyes yellow ; legs greenish or bluish-yellow ; ends of several primaries dusky-blue, rest of plumage pure white. Habitat. — New Jersey, Illinois and Kansas, southward through Central America and the West Indies to Guiana and New Grenada ; casually north on Atlantic coast to Massachusetts and Maine. This little heron is said to be more diurnal in its habits than others of its family. Its food, collected principally in the daytime, according to different writers, consists of fish, frogs, tadpoles, worms, lizards, small crabs and various kinds of insect-life. Thirty-one of these herons, which I obtained in different parts of Florida, in March and April, 1885, were found to have fed almost exclusively on small fishes. Twenty-six of these birds had only the remains of fish in their viscera. Two others had eaten frogs and insects ; two, insects only, and the remaining bird had in its stomach two small frogs, a few fish bones and scales, with hair of a small mammal. The nest and eggs of the Little Blue Heron are very similar to those of the Louisiana Heron. This bird, according to my experience, is found in Pennsylvania as a casual visitor in the late summer, or early autumn. During the last ten years I have seen two or three (all young) which were taken in the southeastern part of the * From twenty six specimens; one (young) captured August, 1875, in Pennsylvania, the others taken when breeding, in Orange county, Fla. , March, 1885. BIRDS OF PENNSYLVANIA. 63 state. Only live, of over seventy, naturalists and collectors, who have kindly sent me lists of birds found in the different counties of our com- monwealth, seems to have observed this species. Their reports are sub- stantially as follows : Dr. John W. Detwiller, Bethlehem, straggler in Northampton county ; Dr. W. Yan Fleet, Eenovo, straggler in Clinton county ; D. Frank Keller, Beading, accidental visitor in Berks county. Prof. H. Justin Roddy, in a letter sent to me from Landisburg, July 15, 1889, says : "Ardea caerulea is a rare breeder (Perry county). Found a set of eggs June 20, 1885, near the base of Mt. Dempsey." Ardea virescens LINN. Green Heron; Shite-poke; Chalk-line; Ply-up-the-creek. DESCRIPTION (Plate 55). Length about 18 inches ; expanse about 26 ; bill rather stout, about two and a-half inches long, and about half an inch longer than tarsus. Adult, in summer.— Top of head, and lengthened crest glossy green ; sides of head, and neck, except a whitish and dusky streak in front, bright chestnut or maroon ; wing coverts and upper surface of wings and tail feathers glossy green, wing coverts edged with brownish and whitish ; inner primaries with narrow white tips, long scapular plumes bluish-white glossed with green, lower parts grayish, darkest on sides. Bill greenish-black, except mandible on lower surface, also lores and eyes yellow ; legs greenish yellow. Young. — Head less crested and dull greenish-black, back and upper parts gener- ally greenish ; long scapular plumes absent ; wing-coverts much more broadly bor- dered, brown and whitish than adult ; many of larger wing feathers have showy white tips ; chin, throat and front neck, whitish with dusky streaks ; rest of and sides of head rather pale reddish-brown ; lower parts, whitish with dusky stripes ; edge of wing as in adult, white ; colour of eyes, legs and bill very similar to old bird. Habitat.— Canada and Oregon, southward to northern South America and the West Indies ; rare or absent in the middle province. The Green Heron is known by a variety of local names, some of which are much more expressive than elegant. This bird, the most common and abundant of all our herons, is found throughout the state, frequent- ing rivers, streams and ponds. It arrives in this section occasionally as early as the first week in April, from the southern states, where it re- sides when the chilling blasts of winter have frozen over our streams and marshes. This species sometimes breeds in small companies ; gen- erally, however, but two or three pairs are found nesting together. The nests, built of sticks and twigs, are placed in low bushes or small trees adjacent to a stream or pond. The nests frequently are built in apple orchards. Indeed, the largest number of nests that I ever found in one locality was in an apple orchard along the Brandywine, where for several years some twenty-five or thirty of these birds annually resorted. While it is true that I have found these herons breeding in small numbers with the Night and Great Blue Herons in Pennsylvania, and also in Florida in company with the Little Blue, Louisiana and Snowy Herons, and even sometimes in the colonies of Water Turkeys and Cormorants, I 64 BIRDS OF PENNSYLVANIA. think, as a rule, they usually prefer to remain by themselves during- the season of reproduction as well as at other times. Various writers state that the eggs are four in number. I have examined many nests, and consider the usual complement to be not less than five ; frequently six eggs are laid. The eggs are pale-blue and larger than those of our com- mon pigeon. This species feeds much more frequently on insects than other of the herons that reside with us. Nuttall writes of the Green Heron in the following language : " He is also particularly attracted by artificial ponds for fish, not refraining even to visit gardens and domes- tic premises which any prospect of fare may offer. He is, at the same time, perhaps as much in quest of the natural enemy of the fish, the frog, as of the legitimate tenants of the pond. These bold and intrusive visits are commonly made early in the morning, or towards twilight, and he not unfrequently. when pressed by hunger, or after ill-success, turns out to hunt his fare by day as well as dusk, and, at such times, collects various larvae, particularly those of the dragon-fly, with grasshoppers and different kinds of insects. At other times he preys upon small fish, crabs and frogs, for which he often lies patiently in wait till they reap- pear from their hiding places in the water or mud, and on being trans- fixed and caught, which is effected with great dexterity, they are com- monly beaten to death, if large, and afterwards swallowed at leisure."

Bill very stout and thick ; maxilla slightly curved ; bill and tarsus each about 3 inches long; head and neck large, the latter quite short; body rather short and heavy. Adult.— Length about 25 inches ; alar extent, about 44 ; bill black ; lores greenish- yellow ; eyes red ; legs yellowish ; top of head and middle of back glossy-greenish BIRDS OF PENNSYLVANIA. 65 black (sometimes dull black with little or no greenish) ; a narrow stripe on fore- head reaching to eye ; sides of head, chin, throat and under parts white, of ten tinged with a faint yellowish or a very delicate light purple color : wings and tail ashy- blue ; neck, except in front, similar but paler. The adults frequently have 3 long and white occipital feathers, which, when rolled together, appear as one thick round feather. Youny.— Bill (dried skin) black and yellowish ; iris light yellow ; legs yellowish ; upper parts light-brown, spotted or streaked with whitish ; tail about same as adult ; sides of head and neck, and under plumage generally, striped with whitish and dusky. A young bird before me differs from the last chiefly in having top of head and large space on interscapular region, dull brownish-gray, without spots. Habitat. — America, from the British possessions southward to the Falkland Islands, including part of the West Indies. Next to the Green Heron the Night Heron is unquestionably the most abundant of the family in this state. The adult birds are easily distinguished from other herons by the black feathers on top of head and back, red eyes, and frequently three long, fine, white feathers, which grow from the base of the head. The appellation, Night Heron, is highly appropriate, as this bird is strictly nocturnal in its habits. During the daytime the Night Heron is inactive, and generally is found perched on a log or the limb of a tree in a quiet nook about the swamps and streams. As twilight approaches this drowsy wader becomes, as it were, a new being — impelled, no doubt, by the pangs of hunger — he stands erect, the loose and shaggy plumage, which before seemed ill- adapted to his body, now fits neat and closely as he carefully walks to the extremity of the dead and decorticated limb on which he has been dozing, and suddenly with a loud squaivk launches himself into the air, uttering at short intervals his harsh note, and, rising above the trees of the forest, he speedily visits some favorite mill-dam. These birds arrive in Pennsylvania about the 25th of April and remain until the latter part of September. They seem to repair at once on their arrival in spring to localities where they are accustomed to breed. After the breeding sea- son, i. e., about the middle of August, when the young are amply able to provide for themselves these birds forsake their nesting-places and become quite plentiful along the rivers, streams and bushy marshes. The Night Heron rarely, if ever, breeds singly, but always in large companies. I have visited, on different occasions, two of these breeding resorts and found from twenty -five to seventy-five nests, which like those of the other species, were built of sticks and placed usually In high trees. In Berks county, near Blue Rock, for many years, this species annually reared their young in the edge of a large woods along the margin of which was a good-sized stream. In this place many of the nests were built in a bunch of saplings, some fifteen or twenty feet high and so small in diameter that it was impossible to climb them. Wilson has very properly said that the noise of the old and young in one of these breeding-places would induce one to suppose that two or three hundred Indians were choking or throttling each other. The same 5 BIRDS. BIRDS OF PENNSYLVANIA. writer, in referring to examinations which he made, states that the teeth of the pectinated claw were thirty-five or forty in number, and, as they contained particles of the down of the bird, showed evidently from this circumstance that they act the part of a comb to rid the bird of vermin in those parts which it cannot reach with its bill. The late Isaac G. Darlington, of West Chester, some years ago, had large numbers of gold-fishes in a pond near his residence. One day Mr. Darlington caught twenty-five of these fish and placed them in a small pool, intend- ing to remove them the following morning. About bedtime, Mr. D. said, I heard a loud squawking, and on going out saw two Night Herons actively engaged in catching these fish. I shot one of these robbers, which you there see mounted, on the book-case, and on making an in- vestigaton found only one of the fish remaining. "An incident may illustrate the habits of the Night Heron, and perhaps of the whole family. A Night Heron had been noticed for several days sitting on a tree near a branch of White Clay creek. It was at length shot and brought to me, with the tail of a large fish projecting four inches beyond its bill. On removing the fish (a sucker Catostomus, which must have been twelve inches long), its head and shoulders — except the bony por- tions— were eaten away by the gastric liquor of the stomach." — Michener. I have examined the stomachs of twenty odd of these herons, adult and young, which have been shot in June at the breeding-grounds, and found in all only the remains of fishes. In two or three immature birds, taken in August and September, I have discovered a few grasshoppers and portions of insects. NOTE. — The Yellow-crowned Night Heron (N. violaceus) which is found in eastern North America, "from the Carolinas and the lower Ohio valley south to Brazil," has not, within the last twenty years, to my knowledge been observed in Pennsylvania. Dr. Turnbull, * writing of this species says: "A rare straggler from the south. It has been seen on the borders of the Schuylkill near Philadelphia." * Birds of Kast Pennsylvania and New Jersey, published in 1869. Plate 15. Red- tailed Hawk. L Male: 2. Female.

Six species are found in Pennsylvania either as summer residents, spring and fall migrants or casual visitants. These birds are difficult to flush, and when started they fly usually in a feeble manner, going mostly but a short distance when they alight and hide in the thick vegetation abounding in the marshes and swampy places which they inhabit almost habitually. Rails, when surprised in their marshy re- treats, seem to prefer to escape by skulking in the reeds and grasses, but if closely pressed they make short flights, dropdown suddenly, and secrete themselves or run with outstretched wings over extensive spaces of water, on which scattered leaves, blades of grass, or twigs, are resting. Rails, when wounded, particularly if winged, frequently escape by swimming. It is surprising how rapidly these slender-toed birds can escape in this manner ; they also are quite expert in diving, and some- times to escape their enemies will remain for a considerable time under the water — clinging by the long toes to plants — with only the bills above the surface. Rails lay six to twelve whitish, yellowish, or grayish and spotted eggs, in shallow nests built of blades of grass, reeds or small sticks, supported by tough grasses or rushes in ponds and marshes. The downy young of the King, Virginia, Clapper and Sora Rails are black. These birds feed largely on seeds, the tender leaves and buds of various water plants. They also eat cray-fish, worms, beetles and other insects. The Clapper (on salt-water marshes of Atlantic coast) and Sora Rails, which are killed in great numbers by sportsmen, are very highly esteemed game birds. The other species, equally as palatable, but with the exception of occasional examples of the King and Virginia Rails, are seldom seen in our markets. The Sora, and scatter- ing individuals of other species, particularly the Virginia and King Rails, are often found, in August and early in September, in considerable numbers, in suita- ble locations, in different parts of this state. Sometimes during cloudy weather, at twilight and often in the night, particularly in the spring and breeding season, the loud, grating cries of these birds are heard in the meadows and marshes. In the genus Rallus the slender and slightly curved bill is much longer than the head : maxilla, particularly in the King Rail (elegans) and Clapper Rail (crepitans) with long and rather deep furrows, which start above and behind the linear nostrils and extend beyond basal half of bill. In Porzana the bill, shorter than head, is straight and thick with rather short, broad fossae, deepest in front of the narrow nostrils. The head is feathered in front, i. e., no broad horny frontal plate as in Coot and Gal- linules; tibiae naked below ; toes, long and slender, without lobes or marginal mem- branes, and the wings are short and round. The tail has twelve short feathers. GENUS RALLUS LINNAEUS. Rallus elegans A.UD. King Rail; Big Red Rail. DESCRIPTION. I
