NORTH AMERICAN FAUNA. 



[NO. 27. 



Colymbus nigricollis californicns (Heerm.). American Eared Grebe, 

 A specimen taken by Kennicott at Fort Resolution, Mackenzie, is 

 in the National Museum. This seems to be the only authentic record 

 for the region. A specimen recorded by Russell from Fort Rae,'^ 

 proves on examination to be referable to C . aurifus. 



Podilymbus podiceps (Linn.). Pied-billed Grebe. 



In 1903, on May 14, we saw two individuals at Two Lakes, Alberta, 

 about 50 miles north of Edmonton. Previously the species was 

 known from this region only from the capture of a few individuals 

 about Great Slave Lake, and apparently is rare. Richardson quoted 

 from Sabine a description of a specimen which he said was killed at 

 Great Slave Lake in May, 1822.^ Ross listed it as rare at Great 

 Slave Lake.^ Baird, Brewer, and Ridgway record eggs from the 

 same place and I find a specimen in the National Museum (No. 

 20756) taken by Kennicott at Fort Resolution, June 13 [1860], and 

 marked " with 4 eggs." These are probably the eggs referred to by 

 Baird, Brewer, and Ridgway. 



Gavia immer (Briinn.). Loon. 



The great northern diver occurs in summer throughout the region 

 north to the Arctic islands, arriving with the breaking up of the ice. 

 In 1901 we heard its notes at the mouth of Peace River, on the night 

 of June 5, and on July 15 and 16 on the Northern Arm of Great 

 Slave Lake, near Yellowknife Bay. 



In 1903 we saw the species on Athabaska River, near Grand Rapid, 

 May 20; at Fort Chipewyan, June 5; and on Rocher River, June 6. 

 After leaving Fort Resolution for the Mackenzie, Alfred E. Preble 

 and Merritt Gary observed two near Sulphur Point, Great Slave 

 Lake, June 27. They noted the species also near the mouth of 

 Nahanni River, July 15 and 17; about 20 miles above Fort Wrigley, 

 July 20; between Fort Wrigley and Fort Simpson, July 23; and on 

 Great Slave Lake, near Fort Rae, July 28. On their return trip they 

 saw several on Lily Lake, Alberta, 34 miles north of Edmonton. 

 September 24. I noted the species at Fort Resolution, June 28, and 

 near Gros Cape, Great Slave Lake, July 23. I found it breeding 

 commonlv during August on nearly all the lakes on the route fol- 

 lowed between Fort Rae and MacTavish Bay, Great Bear Lake, and 

 noted several pairs with young during the early part of the month. 

 I saw a pair with young the size of green-winged teals on Lake 

 Mazenod, near the head of Grandin River, August 6, and noted the
