would be a second laying. After the middle of August none are 
seen. (Rev. C. J. Young.) Breeds commonly in Manitoba where I 
have found several nests containing five eggs each. (W. Raine.) 
CC. MOLOTHRUS Swainson. 1831.

Molothrus ater (Bopp.) GRay. 1870. 
Apparently not noticed in Nova Scotia. 
A rare summer resident in New Brunswick. (Chamberlain.) 
Taken at Beauport; not a common summer resident in Quebec. 
(Dionne.) 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 
acowbird. (Winitle.) 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 congregates 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 ob- 
served 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.) Abundant summer resident 
at Toronto, Ont. I first saw 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. Taverner 
reported them as common at Beaumaris on April 22nd, 1898. 
(J. H. Fleming.) Common all over western Ontario. (W. E. 
Saunders.) One seen at Missinabi, Ont., June, 1904. (Spread- 
borvugh.) 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
