CATALOGUE OF CANADIAN BIRDS. 393 
not a common summer resident in Quebec. (Déionne.) 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. (Wntle ) 
A common summer resident at Ottawa, Ont., laying in many 
small bird’s nests. (Ottawa Naturalist,Vol. 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, I 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./. Young.) 1 firstsaw this birdat 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. Mleming.) 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. (Cowes.). An abundant summer 
resident throughout the whole prairie region. (Zhompson-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 mountairs, 
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, BG.
