Haliaeétus leucocephalus alascanus Townsend. 
Northern Bald Eagle. 
The bald eagle was found common alone the sea shore in 
nearly all parts of the region explored. At Mole Harbor, Ad- 
miralty Island, Stephens records seeing as many as twenty eagles 
together at one time. At Windfall Harbor and Hawk Inlet they 
were common; but about the lakes in the interior of Admiralty 
only one was seen. At Red Bluff Bay, Bear Bay, and Rodman 
Bay, Baranof Island, they were noted. At the latter point, 
Stephens saw a nest, August 19, with young able to fly and 
parents about. At Hooniah, Port Frederick, and Idaho Inlet, 
Chichagof Island, the species was common, as it was also on the 
mainland shores at Glacier Bay and Helm Bay. It is undoubt- 
edly permanently resident in the region. The chief diet of the 
bird everywhere appeared to be rotting salmon; hence it was 
always more numerous around the mouths of the salmon streams. 
Oceasionally eagles were seen actively catching small fish which 
were frightened to the surface by loons. 
One skin was preserved (No. 11). This is of an adult female 
and shows the following measurements: wing, 610 mm.; tail, 
335; tarsus, 95; chord of middle claw, 48; chord of culmen from 
cere, 58.5; bill from nostril, 49; eulmen, 69. This bird, meas- 
ured by Dixon when first taken, had a length of 37 inches, and 
a spread of 6 feet 10 inches; its weight was 1314 pounds. <An- 
other female, made into a skeleton, had a leneth of 37 inches, a 
spread of 7 feet 9 inches, and weighed 15 pounds. A male had 
a leneth of 37 inches, a spread of 6 feet 10 inches, and weighed 
1314 pounds, the same as the female above noted. 
At Windfall Harbor, April 30, Dixon seeured a set of two 
fresh eggs. The nest was located on the north end of Windfall 
Island on the broken-off top of a large tree standing on a ridge. 
The tree was 314 feet in diameter, and the nest was 11614 feet 
from the ground. Before it could be reached, three adjacent 
trees were felled, the last one lodging against the nest tree. The 
brooding eagle remained on the nest until Dixon was within 
reach, when she flew off, and the two birds kept circling about 
and squealing, but offered no active opposition. The nest was
