1918.] Birds of Alix, Buffalo Lake, and Red Deer. 477 



XXIY .—Further Notes on Birds observed at Alix, Buffalo 

 Lake, and Red Deer in the Province of Alberta, Canada, in 

 1915 and 1916. By Charles B. Horsbrugh, Canadian 

 Army Medical Corps, B.E.F. 



These additional notes on the birds of Alix, Bufifalo Lake, 

 Red Deer, and other districts {vide ' Ibis,' 1915, pp. 670-689) 

 are the result of my change of residence to Red Deer in 

 October 1915, and better opportunity to extend my obser- 

 vations over a wider territory. During the early spring 

 and summer of 1916 the weather was, as in the previous 

 year, disagreeably wet, and snow fell early in November. 

 Red Deer, which lies nearly halfway between Edmonton and 

 Calgary, is as well-wooded, watered, and hilly as the Alix 

 country, and offers a good field for ornithological study. 

 It lies 2860 feet above sea-level. A Natural History Society 

 has been in existence for a few years, the reports of which 

 are published annually in the Journal of the Government 

 Agricultural Society. 



The nomenclature and classification, as in the previous 

 paper, are that of the A.O.U. Check-List. 



iEchmophorus occidentalis. Western Grebe. I visited 

 the same colony reported in my notes for 1914 on 28 May, 

 1915, finding plenty of nests with full clutches and birds aJ 

 numerous as in the previous season. I received a specimen 

 picked up alive near Red Deer on 17 November, which died 

 next day. Mr. P. A.Taverner, of the Victoria Memorial 

 Museum, Ottawa, writes me as follows:— " One of the 

 Western Grebe's sk-ins is an interesting bird, being the form 

 clarkii, originally described as an independent species but 

 now regarded as a variant form of the Western. It is charac- 

 terized by its smaller size, different coloration of lores and 

 bill, and by having a recurved bill like the Avocet.'' My 

 knowledge of this subspecies is insufficient to add anything 

 to the above. 



Gavia immer. Great Northern Diver. A single specimen 

 was seen on a large lake a few miles south of Alix on 3 April,
