Common migrant; a few breed. Dufferin: Arrived between April 25 and 30 (Dawson). Specimen in Smithsonian Institution, from Red River Settlement (Blakiston). Winnepeg: Abundant (Hine). Red River Valley: Abundant migrants, but I can not concur that it commonly breeds in Manitoba (Hunter). Breeding at Lake Winnipeg (D. Gunn). A few breeding in Lake Winnipegosis, June, 1881 (Macoun). Portage la Prairie: Fall migrant; common in spring, arriving as soon as the rivers are open; not so frequently obtained in the autumn, principally, I think, because it confines itself to the large lakes, seldom visiting the creeks or sloughs at that season; it remains until it is frozen out; in 1884, first seen April 16 (Nash, in MSS.).

Carberry: Abundant; migrant (Thompson). Qu’Appelle: Common summer resident; breeds; arrives April 20 in flocks, with lesser Blue-bills and Ring-neck (Guernsey).
