Its greatest length from north-west to south-east, is about 60 miles, its greatest breadth about 27 miles. The gen- eral slope is toward the south. The county is for the most part under cultivation. The Avifauna of the county is interesting because of the fact that the difference between the northern and southern portions is very marked, and because its southern boundary appears to form the southern breeding limit for several birds of the Cana- dian zone. Zoogeographically the fauna is Alleghanian, strongly in- clined towards Canadian. Having no beaches our fauna is poor in Limicolae. Most of the Anatidae recorded were seen at Puslinch Lake, a body of water about miles by J mile at the south-west corner of the county, or at Pike Lake, a sheet some 1 mile by \ mile, near Mount Forest. The nomenclature and classification used in this list is that of Coues’ “Key to North American Birds,” (fifth edition), with a few modifications, namely, that the sequence is that of the A.O.U. Checklist, the original spelling of names is preserved and a few sub-species are not recognized, in which last case a note is made of the fact. a \ 2 The Ont. Nat. Sc. Bulletin— No. 1. # . ' . _ r m The “Key” is used instead of the latest A.O.U. Checklist, because the latter sets forth a nomenclature too fleeting in its nature, and graces too many insignificant variations with a name. That every slight variation should be recorded, is certainly of importance, but the naming of them is quite another matter. The writer is greatly indebted to Mr. Allan Brooks, now of Comox, B.C., for a list of the birds observed by him during a three years’ residence at Mount Forest, at the extreme north of the county, and to Mr. P. A. Taverner, of Detroit, Mich., for a list compiled during a two years’ stay at Guelph, also to the members of the Wellington Field Naturalists’ Club, for numer- ous notes furnished. 1.

In Ontario, the Canada Jay has hitherto kept within certain well defined boundaries, which it seldom exceeds, even in win- ter. North of Muskoka it is a regular resident, and in winter rarely passes south of the Muskoka Lakes. In October, 1904, a general migration of Canada Jays into the southern parts of Ontario occurred. The first reports came from Madoc, Hastings County, where they were seen by the Rev. C. J. Young, on October 7, where they remained through November. At Toronto the first were recorded at Fisherman’s Island, a part of the eastern sandbar, on October 15th, by Mr. C. Pickering, and by the 17th were reported from various parts of the city going about in small flocks of from three to eight,, those that escaped destruction remained about the outskirts of the city till late in November. That the Jays should first appear on the lake shore is peculiar, and unless the wide extent of marsh in Ashbridge’s Bay afforded animal food not to: be found in the woods, is hard to account for, though it is possible the migration followed the lake shore. At Wellington, in Prince Edward County, a large flocK was reported on October 21st, and about the same time at Belle- ville. At Penetanguishene, on the Georgian Bay, Mr. A. F. Young gives the following dates, October 25th-3oth, November 12th and 26th; also January 9th and 20th, 1905. In Wellington County, at Hillsburg, on October 24th, at Puslinch Lake on the 31st and again on November 16th, by Mr. A. B. Klugh ; Guelph, November 3rd and 12th, by Mr. E. J. Colgate; and at Rockwood on the 17th. Mr. S. Hunter saw them at Millbrook, Durham County, December 31st. Two were reported at Galt, and Dr. C. K. Clarke found them in the vicinity of Kingston. It will be seen by these few records how general the migra- tion was, and though first noticed early in October, the move- ment must have continued on through November. 12 The Ont. Nat. Sc. Bulletin— No. 1. At the head of Lake Joseph, in Muskoka, I found the birds abundant in the last week of October, and they Jiad been there- all month, if not earlier. About the middle of November they disappeared and were absent during the winter. It is difficult to assign a cause for so unusual a migratipn. It has been suggested that the presence of enemies, such as Owls, has had something to do with it, but the present winter has been noticeable in Toronto for the absence of Owls, only a few of the larger ones being reported ; and in Muskoka, during October and November, Hawks and Owls were very scarce. The food question is likely the real explanation, though why the Canada Jay did not migrate south of Muskoka during the ex- ceptional winter of the previous year, which was preceded by a failure of the usual food supply, such as seeds and nuts in all the country south of the main line of the C.P.R., resulting in great destruction to the Red Squirrels in many parts of Mus- koka and Parry Sound, is hard to say. In the Autumn of 1904 food of all kinds was abundant in all these districts, though it is likely the migration originated far north of the Muskoka country, some cause as yet unexplained, forcing the birds out of their regular winter range. In Toronto we have to go very far back for a parallel to the migration of 1904, in the Canadian Journal, Vol. I., 1852-3, the late Hon. G. W. Allen, one of our earliest naturalists, says : “They appeared in great numbers in the autumn of 1839 and 40, filing about the woods and fields in flocks of fifteen or twenty.” I have two skins from this migration, and it is curious to thi-n!k that a period of sixty-five years should elapse before any more Toronto records were added. The only other unusual record I am aware of is of a speci- men taken at Aylmer, Ontario, November 18, 1901, rcorded by Mr. J. H. Ames (‘Auk, XIX., 1902, p. 94.) The Canada Jay is an exceedingly hardy bird, breeding very early in March, a persistent searcher for food, visiting the lumber camps, or following the hunter or surveyor, ready to steal ary food, no matter how unknown or how risky to get, neglect- ing nothing in its search, but seldom found away from the bush country or out of its regular bounds. Mr. A. Ik Klugh has furnished me with many of the re- cords quoted. Taverner— Kirtland’s Warbler. 13 The Origin of the Kirtland’s Warbler. BY P. A. TAVERNER. Just as a non-essential character in an organic being often forms a better clue to its true affinities and lines of descent than more fundamental structures ; so, the study of a rare and econo- mically unimportant species may be more productive of results than that of wide spreading, dominant forms. In the latter case the v-ery multiplicity of data may be confusing and render it diffi- cult to separate the pertinent from the impertinent, the local phenomena from the general. In following out and determining exact migration routes this is particularly true, and when we attempt to reconstruct the past history of a race the more nar- rowly we confine our attention, the more promise we have of arriving at approximately correct conclusions. Dr. Conan Doyle has made his hero, Sherlock Holmes, say words to this effect, that the more outre and uncommon the conditions are surround- ing a discovered crime, the more easily should the sleuth find out the committer of the deed. This, if the reasoning is sound, should apply as well to scientific as to criminal investigation. In this light it appears that Kirtland’s Warbler ( Dendroica kirt- landi ), affords peculiar opportunities for investigation and per- haps a little speculation along these lines may be of some value, even if the only result that comes therefrom is vigorous attack and final denial. A questionable, or even false, theory, honestly advanced, may be of benefit, for the subsequent discussion and final refutation it may bring forth, if for nothing more. The records of Kirtland’s Warbler are few and mostly far between. The first specimen was likely taken about 1840, though it was not finally described until 1852, from another bird taken by Mr. Chas. Pease, near Cleveland, Ohio, the year before. From time to time various specimens have been taken up and down the Mississippi Valley, and at isolated points in the East, including one record from Toronto, Ont. The winter habitat was found in the Bahama Islands, where it proves to be fairly common, but though Ohio and Michigan were the States accredited with the greatest number of records, it was not until 14 The Ont. Nat. Sc. Bulletin— No. 1. 1503 that its breeding- grounds were found by Mr. Norman A. Wood (Bull. Mich. Ornith. Club, Vol. V., pp. 1-13), in Crawford and Oscoda Counties, Mich., where it seems to be a not un- common summer resident. In the same issue Mr. Adams traced out the probable migration route of the species and followed it from the time it left the island home in the southern seas until it reached its northern breeding area in the Jack Pine plains of Michigan. Some of the theories Mr. Adams founded his argu- ment upon have been challenged by no less an authority thlan Prof. W. W. Cooke (An Untenable Theory of Migration), but the conclusions of the present route which he mapped out has not been questioned. According to this the bird under discussion crosses to the West Florida coast and passes on to the valley of the Mississippi by way of the Pine Barrens of the South. Thence up that great highway. The Michigan individuals branch off from this and enter Michigan along the Ohio River and its branches and reach the breeding grounds by journeying up the eastern side of the State. There may be other breeding grounds not yet discovered, and there probably are such, but this is the sum total of our knowledge of the species at present. The birds do not seem to be a weak race, for at either end of their range they are fairly common and seem to hold their own successfully with the competing forms about them. The extreme localness of their distribution demands explanation and incidentally raises other questions. All life tends towards increase and will do so until some destruc- tive influence prevails to counteract the natural prolificacy of the race. There are always adaptations and influences working both for and against each species. As the population increases the harmful ones increase in greater proportion than the of her, until the time comes when the two antagonistic powers are in equilibrium, when for the time being we have a stationary popu- lation. The abundance of a bird can be regarded as repre- sented by the sum of a long sequence of plus and minus quanti- ties of unknown value. As far as our knowledge goes there is no bar to the increase of Kirtland’s Warbler at the northern end of its range. It is common in certain restricted localities and we can see mi rea- son why it should not be equally common in like situations, of which there are many, elsewhere. That it is not so shows either Taverner— Kirteand’s Warbeer. 15 that we do not understand the required conditions, which is probable, or else that the check comes at some other point of its range, which is more probable still. Up and down the migration route our knowledge of the bird and its needs is too fragmentary to afford us any clue, nor is it likely that in its transitory stops at various points it would meet any enemy that would seriously affect its numbers. In the Bahamas, however, the case is different, and we see from the very nature of the situation that the size of its range is very limited. In any certain area but a limited number of individu- als of a species can exist. The food supply alone would be sufficient to support but a certain definite number. Add to this other hostile elements of the environment which inevitably occur and the number capable of existing there is still further reduced. The conditions may vary at times, and with them the population, but in each and every caSe, under a certain given set of surround- ings, but a certain number of individuals can survive and the question of population becomes one less of how many are born than how many can survive. If, then, the Bahama Islands are the only winter quarters of the bird, it follows that however many birds are successfully raised during the breeding season, but a limited number can survive the winter for the return migration in the spring, and the number can never permanently increase unless the area of the winter quarters increases, or the conditions" prevalent there become modified so as to support a denser population of the species. It seems highly improbable that the species could ever have originated under these conditions. Isolation produces speciali- zation, but it must be during the breeding season to have any great effect. At other times incipient species may freely inter- mingle with the original stock without losing their entity. In a case like Kirtland’s Warbler, any decided departure from type would occur to the species as a whole and not to the small group of them separated from the rest during the non-breeding season. The insular habitat then could not have been the cause of dif- ferentiation in this species, and we must look elsewhere, prob- ably upon the adjoining Continent for the original range of this family. 16 The Ont. Nat. Sc. Bulletin— No. 1 The Pine Warbler ( Dendroica vigor si), is a very near rela- tion of D. kirtlandi, and its range, as given in the A.O.U. Check list is suggestive. Eastern N. America to the Plains. South in winter to the Gulf States and the Bahamas. Imagine the ancestors of our Kirtland’s Warblers as having a similar range, and suppose that some of the changes continually taking place in environments render the southern continental parts unhabit- able to this particular species, we have then, as a result, just the peculiar distribution that we, are now investigating. It seems likely that individuals inhabiting adjoining localities in the winter habitat would migrate to approximately the same terri- tory in the summer one. This would account for the limited area and comparatively dense population of the breeding grounds. There being but slight competition within the species they would spread out over no more ground than was absolutely necessary for securing a comfortable existence. On the other hand, supposing that the Bahaman birds scattered all over the northern breeding grounds in summer, the result would likely be the same. Some localities would raise birds slightly stronger and finer than the rest, and when the whole species returned to the southern regions and were subjected to the strict selective process, caused by the struggles between the season’s natural increase and the finally surviving number, the weaker ones raised in the less favored localities, would be the ones eliminated and the tendency would be towards the localization of breeding communities in the most favored of the summer stations.. It seems probable, then, from our present knowledge, that Kirt- land’s Warbler is what remains of a once far more widely distri- buted species wintering along the Gulf States and spread from thence to the Bahama Islands. They migrated up the Missis- sippi Valley and perhaps also up the Eastern States, which would account for our records at Washington and elsewhere along that line. The breeding grounds then likely covered the greater part of the Alleghaniah Transition Zone. Changed conditions ren- dered this continental portion of the southern habitat untenable for a permanent winter residence, and the species became ex- tinct there, leaving the Bahaman individuals the only surviving representatives of the race. These continued to follow their old route, passing rapidly, and perhaps, at the mpst favorable time Young — Thrushes of East. Ont. 17 of the year, over the now hostile territory to the grounds where we now find them. Thus, if the foregoing reasoning is reasonably correct, un- less man, or some other agency steps in and exterminates the little isolated breeding colonies, the future of Kirtland’s Warbler depends upon the conditions prevalent upon the southern habi- tat, and unless the hostile influences in the surrounding terri- tory then moderate to allow them to extend their present winter range or re-inhabit their old one, the species can never become a common one again. The greatest danger to them lies, of course, in the Bahama Islands, each bird destroyed there after the economic equilibrium has been established, means one less breeding bird for the next spring, while beyond a certain point the destruction of a few individuals here will do no injury to the species. But care must be exercised in the case of so small a race that the number killed does not exceed that of the natural surplus, and to guard against this the attitude of protection that the Game Warden of Michigan has taken in regard to this bird is perfectly justifiable and commendable. The Thrushes of Eastern Ontario. BY C. J. YOUNG. The birds of this genus are not known or appreciated as much as they should be. Their haunts are our swamps and woodlands. The bright summer foliage shelters them and, they delight in seclusion and solitude. Only .two Thrushes are com- mon in Eastern Ontario; the Wilson’s Thrush, and the Hermit Thrush, the former being the most abundant. The Wood Thrush is occasionally met with and the Olive-backed on migra- tions. To a student of birds the distinguishing of the various species is not difficult, and their nesting habits are somewhat disimilar. The first of these birds to arrive in spring is the Hermit Thrush. He is a splendid songster, and makes his presence known soon after his arrival. I have met with him in the Coun- ties of Renfrew, Leeds and Frontenac. Not only does his song distinguish him, but the coloration of hi§ back and tail, the for-. 18 The Ont. Nat. Sc. Bulletin— No. 1. mer olive, the latter evidently rufous. A number of the birds we see in April and early May pass northward and eastward to breed. Comparatively few do so with us. In the middle of May I have seen this bird not uncommonly in the second growth bush through which the road that leads from Clarendon to Ar- doch in North Frontenac, passes. Several were perched on the topmost boughs of a small tree, noticeable songsters in that dreary section of country. Mr. Saunders says this species pre- fers dry ground as a rule, and an elevation. My observations agree with this statement, but I find the eggs are distinguishable from the Wilson’s. In June, 1888, I found a nest near Ren- frew, on the ground on a bank, sheltered "by a gooseberry bush. It contained two eggs. They were a trifle larger than the Wil- son’s, and almost as light in color as a bluebird’s. Two eggs taken from a nest in the side of a rotten stump in a cedar swamp near Ompah, Frontenac County, were similar in color, and both these sets agreed with a set taken in S. Labrador, from a nest located under a scrubby Spruce. I have only seen a few sets, and do not consider the bird a particularly common breeder here. The next Thrush to arrive is the Olive-backed. I have only met with it on migration. The colors are very uniform, an olive brown from head to tail. I am only sure of having seen one in Ontario. That one I picked up by the roadside, near Lansdowne, Ont., it having probably struck a telegraph wire and been killed. It does not appear to breed with us, at least I never saw or heard of a nest. Its breeding habits are so characteristic and different from the other Thrushes, as to the eggs, which are freckled, not plain blue alone, that one could not overlook them. Not even in N. Frontenac does it appear to breed. It does so in New Brunswick, in the Magdalene Islands, and abundantly on the north shore of the Gulf of St. Law- rence, from whence I have seen the eggs. Wilson’s Thrush comes next on our list. I am not sure whether this species or the Wood Thrush is first to arrive, but I think they do so at about the same date, both a little later than the Hermit. It is a common bird, frequenting moist woods, swales and sometimes willow -swamps. Neither is it at all local, being equally at home in Ontario and Quebec, as in the Maritime Provinces; in the Magdalene Islands, and along the north shore of the Gulf. Its plumage is very uniform, a tawny brown from head to tail, 19 Fleming— Thrushes of East. Ont. while the spots on the breast are smaller than in the case of the Hermit or the Wood Thrush. This Thrush commences to build its nest the second week in May. I have found many of their nests, generally in damp woods, but not always. Last summer (1904), I found one placed on a fallen bough in a very dry place. The bird was sitting and I approached within two feet of her before she left the nest. Another I found in thick raspberry canes, one in a bunch of Ferns (O smunda claytonianci ), others on the ground, still another in a willow thicket among the sprouts of a thick willow. Most of the nests I have found have been slightly raised above the ground, but never more than eighteen inches, or at most two feet. The eggs are darker in color than either the Hermit's or the Wood Thrush’s. Some I have seen almost as dark as a Catbird’s. I have noticed too that they vary much in size. The set I found in the willow thicket were scarcely larger than Song Sparrows’, the majority about the size of Bluebirds’. None as large as the lighter colored Hermit’s. The usual number of eggs is four, but very often three complete the set. Once only, did I find five in a nest, and I think this number is exceedingly unusual. To those who ramble through the woods this bird will al- ways be an interesting friend, it is comparatively tame and confiding, is easily identified, and frequently met with. Though not. in a hurry to take up its summer abode with us, it is loath to leave. I have seen it occasionally in the woods in the late fall as late as October, when our other bird friends have left us. At that season, when on the point of leaving, it sometimes visits our gardens, and the neighborhood of houses, regretfully leaving the woods, then rich with autumn tints. That large and handsome bird, the Wood Thrush, is not common in Eastern Ontario. It is larger than the other Thrushes, its plumage is brightest on the head, and this mark and the large spots on its white breast will readily identify it. I have only met with it the last few years, in woods near Lansdowne, chiefly second growth, but with a few large trees ; in a similar wood near the St. Lawrence, where I saw a nest in a small beech tree; and in Frontenac county, where in 1903 I met with another nest built on a horizontal bough of a Hemlock, about 'eight feet from the ground. 20 The Ont. Nat. Sc. Bulletin— No. 1. This Thrush is a fine songster, it delights to sing in some remote corner of the woods on a summer’s evening, and its notes are readily recognized. Its nest is peculiar and also helps to dis- tinguish the species, for it never builds on the ground, always locating it at an lelevation of six feet or upwards. There is one peculiarity in the nest which I have noticed, that seems to dis- tinguish it from the other Thrushes — that is, that as well as using mud in its construction, a lining of black fibrous roots is introduced, on which the eggs are laid. The latter are exactly the color of a Robin’s, but decidedly smaller, hardly as dark as the Wilson’s, and might be described as resembling very small Robin’s. I think the bird but seldom breeds in these counties; it is more at home in Western Ontario and further south, and the nest I met with in N. Frontenac I considered an unusual occur- rence. So much for our four Eastern Ontario Thrushes ; they are all interesting, and their arrival should be looked forward to, as speaking of respite from frosts and cold, and bidding us with them rejoice in the bright hours of the Canadian summer..
