GENERAL ACCOUNTS OF THE BIRDS 



Colymbus holboellii (Reinhardt). Holboell Grebe 

 Present during our entire stay in the region. Pairs were seen in 

 various lakes, large and small ; and early in June the curious courting 

 antics were commonly observed. No nests were found, nor were any 

 young birds seen. 



Colsmibus auritus Linnaeus. Horned Grebe 

 A pair or more could be found on every lake, large or small. Seen 

 at Carcross, May 22, and a single bird was noted near Atlin on 

 September 21, my last day afield. Migrating in numbers during the 

 second and third weeks in September. 



On July 18 a nest was found in a small lake at the head of Canon 

 Creek, about 3500 feet altitude. The young birds had apparently but 

 just hatched. They, with one parent, were occupying the nest when 

 it was found, and the family, as observed from a distance, returned 

 to it when I left. The nest was a circular mass of sodden grass floating 

 amid a sparse growth of short, green grass, about three feet from the 

 shore. It was somewhat hidden by a small willow overhanging from 

 the adjacent baoik.
