GENERAL ACCOUNTS OF THE BIRDS 



Colymbus holboelli (Reinhardt). Holboell Grebe 

 A pair was nesting on Sawmill Lake in June. They kept far out 

 on the lake, but with binoculars we were able to determine their specific 

 identity. • 



Colsonbus auritus Linnaeus. Horned Grebe 

 Small grebes were seen on Sawmill Lake several times during June, 

 always at a great distance, and on June 12 a pair was seen on Alkali 

 Lake. 



Gavia immer (Briinnich). Common Loon 

 At least one pair on Sawmill Lake. The birds were quiet and un- 

 obtrusive, never being heard calling at that point. Another pair, 

 encountered in a small lake near Doch-da-on Creek, was more noisy, 

 and our arrival at the lake shore was invariably heralded by an out- 

 burst of sound from both birds. At that time, the middle of July, 

 they were caring for two young, apparently about a third grown. The 

 four birds were almost always seen together.
