Colymbus auritus Linnaeus. Horned Grebe. 
Only one specimen of this grebe was seen by any of the party. 
After a long boat-chase by Stephens and Littlejohn among the 
Beardslee Islands, Glacier Bay, July 14, the bird was fortunately 
secured. It is a male, No. 86, U. C. M. V. Z., and is in adult 
summer pluma ge. 
Gavia immer (Briinnich). Common Loon. 
This species was of more or less common occurrence around 
Admiralty Island and on Glacier Bay. In the first-named region, 
at Windfall Harbor, May 16, an adult male was secured (No. 17), 
and the species was quite common for the next few days. On 
the chain of lakes back of Mole Harbor several pairs were seen 
at various times between May 19 and June 11. They were evi- 
dently breeding, though efforts at finding nests failed. Little- 
john’s notebook records that loons were seen in numbers at Mole 
Harbor on May 19 and afterwards. Each morning and evening 
these birds were occupied in feeding on the herring, an abundant 
fish in the waters of this, their spawning ground. While the 
loons were diving for fish, great flocks of glaucous-winged gulls 
and numerous bald eagles hovered above the water watching for 
the herring which were driven to the surface. A loon shot in 
the act of swallowing a herring just caught showed the fish to 
be swallowed whole. Dissection showed four more fish in the 
bird’s crop. At Coppermine Cove, Glacier Bay, Dixon saw a 
pair of common loons in a small lake, half a mile back from the 
beach. A nest and two eges were reported to have been found 
on a small island in the lake in May. 
Gavia adamsii (Gray). Yellow-billed Loon. 
Mr. Littlejohn feels confident of having seen an individual 
of this rare species at Windfall Harbor, Admiralty Island. The 
bird was pursued for an hour or more, but could not be ap- 
proached closely enough for an effectual shot. On several ocea- 
sions the large yellow bill was plainly seen, so that there seemed 
little doubt of the identity. It is very regrettable that the speci- 
men was not secured.
