ica east of Hudson Bay and Lake Huron. The extreme 

 easterly points at which the species breeds are around 

 Lake St. Clair and the western end of Lake Erie in Ohio, 

 Michigan and Ontario; thence westward, a few breed 

 in northern Indiana (Kewanna, English Lake), southern 

 Wisconsin (Delavan, Lake Koshkonong), northern Iowa 

 (Spirit Lake, Clear Lake), northern Nebraska (probably 

 in Cherry County), Montana (common) and central Brit- 

 ish Columbia (Cariboo District.) The species is rather 

 rare on the Pacific coast and seems to have been found 

 only once on the coast of Alaska (Portage Bay, near Chil- 

 kat River), though not rare inland on the Yukon River, 

 breeding as far north as Circle City. The principal breed- 

 ing range of the lesser scaup is the interior of Canada, 

 from northern North Dakota and northern Montana to 

 the edge of the timber near the Arctic coast in the Ander- 

 son River and the Mackenzie River regions. 



Migration Range. The route of migration in the fall 

 evidently tends toward the southeast, for at this season 

 the species is not uncommon in New England and is a 

 rare visitant of Nova Scotia and even of Newfoundland 

 and is accidental in Greenland and the Bermudas. 



Aythya collaris (Donov.) Ring-necked Duck. 



Breeding Range. The summer home of this species 

 seems to comprise two general areas separated by the 

 Rocky Mountains. The greater number breed in the in- 

 terior, from North Dakota and Minnesota north to Atha- 

 baska Lake and east to the western side of Lake Winni- 

 peg. It breeds rarely south to southern Minnesota (Min- 

 neapolis, Heron Lake), northern Iowa (Clear Lake) and 

 to southern Wisconsin (Lake Koshkonong; Pewaukee
