Haliaeetus leucocephalus alascanus Townsend. 
Northern Bald Eagle. 
One adult specimen of the bald eagle (no. 1134) and six 
young of various ages (nos. 1135-1139) were preserved, all from 
Hawkins and Hinchinbrook islands under dates ranging from 
June 26 to July 16. Also observed at Montague, Green, Knight, 
Chenega, Dise, and Naked islands, and at Port Nell Juan, Valdez 
Narrows, and Cordova. At most of these points nests were to 
be seen, and the birds themselves were conspicuous. This is, 
therefore, one of the characteristic components of the ayifauna 
of the region. Dixon has elsewhere reported fully his obser- 
vations on the habits of the northern bald eagle, including what 
was learned during the present Expedition. (See Condor, XJ, 
November, 1909, p. 187.) 
Falco columbarius Linnaeus. Pigeon Hawk. 
At the head of Port Nell Juan, August 16, a pigeon hawk 
(no. 1174) perched on the mast of the boat, from which it was 
shot. Several were seen by Heller at Chenega Island, where one 
(no. 1175) was taken August 31; two more were noted at Valdez 
Narrows late in September. Both specimens are females, ap- 
parently immature. Neither show the characters of F. c. suck- 
leyi; and lack of material prevents my drawing comparison with 
birds from eastern North America. Their wing-lengths are, 
respectively, 210 and 215 mm. 
It seems probable that this hawk is merely a migrant through 
the Prince William Sound region. : 
Bubo virginianus lagophonus (Oberholser). 
Ruddy Horned Owl. 
Owls of any sort were rare in the region. An undetermined 
small species was reported from the head of Cordova Bay. At 
this place Dixon flushed a horned owl June 13. Heller heard 
a Bubo at the head of Port Nell Juan. The only owl secured 
was shot by Dixon at Canoe Passage, Hawkins Island, June 25
