CATALOGUE OF CANADIAN BIRDS. 393 



not a common summer resident in Quebec. {Diomie.) A common 

 summer resident around Montreal ; breeds in many small bird's 

 nests ; I have observed a nest of the yellow warbler rebuilt on top 

 of the first nest which contained the eggs of a cowbird. {Wintle ) 

 A common summer resident at Ottawa, Ont., laying in many 

 small bird's nests. {Ottawa Naturalist,Yo\.V.) Very abundant 

 in Ontario, arriving in April and staying until October. It con- 

 gregates in small flocks through the summer. I have seen its eggs 

 in May, June and July; in the latter month usually in the nest of the 

 song sparrow, or wood pewee. I have seen this bird in the winter 

 in company with English sparrows. In December, 1889, 1 saw two 

 at Lansdowne, Ont. ; one of these remained with a flock of 

 sparrows all the winter. This was the same winter I observed 

 red-headed wood-peckers, the weather being unusually mild, and 

 there being only two weeks of sleighing along the St. Lawrence 

 all that winter. {Rev. C.J. Young) I firstsaw this bird at Emsdale, 

 Muskoka District, May 26th, 1899 ! about a dozen of both sexes ; 

 Mr. Kay gives 1889 as the year of their first appearance at 

 Gravenhurst ; Mr. Tavernier reported them as common at Beau- 

 maris on April 22nd, 1898. (/. H. Fleming!) Common all over 

 western Ontario. {W.E.Saunders?) I have nowhere found the 

 cowbird more abundant than it is in summer throughout the region 

 surveyed by the commission. Even were the birds not seen 

 ample evidence of their presence in numbers .would be found in 

 the alien eggs with which a majority of the smaller birds of the 

 country were pestered. Scarcely any species, from the least 

 flycatcher and the clay-coloured bunting up to the towhee and 

 kingbird, escapes the infliction. {Coues.) An abundant summer 

 resident throughout the whole prairie region. {Thompson-Seton!) 

 Extremely common throughout the whole of Assiniboia and 

 dropping their eggs in all kinds of small birds' nests in the sum- 

 mer of 1894. In 1895, the prairie was traversed in a westerly 

 direction for 500 miles ; in all this distance it was a common 

 object around our camps ; this species is rare in the mountains, 

 only two males were taken at Canmore, Rocky Mountains, in 

 1891; but it was common at Edmonton, Alberta, and southward in 

 the foothills to the Crow's Nest Pass ; two specimens reached 

 Revelstoke in company with a yellow-headed blackbird on May 

 25th, 1890, and later in June a number of males were seen along 

 the beach at Deer Park, Arrow Lake, Columbia River, B.C. ; 

 observed one specimen at Huck's ranch, Chilliwack River, B.C.,
