Land Birds. 



Haliaeetus leucocephalus alascanus. Northern Bald Eagle. — 

 Estimated numbers. Nesting birds, thirty pairs. Young in nests, sixty. 

 Immatures of past two years, eighty. Total, 200. At the time of my 

 arrival on the island, May 23, the young were already hatched. They 

 had apparently not yet left the nests August 15. The eagles on Forrester 

 Island seem to subsist nearly altogether on fish, though on a few occasions 

 they were seen in pursuit of sea birds. 



Falco peregrinus anatum. Duck Hawk. — Half dozen pairs nesting. 

 One nest examined June 13 contained two young about two weeks old. 

 Most of the young were flying by July 20 and hunting for themselves by the 

 25th. This hawk appears to feed entirely on other birds, puffins, auklets 

 and murrelets being its chief prey. 



Cryptoglaux acadica. Saw-whet Owl. — An adult female was taken 

 June 5 as she left a cavity in a dead spruce stub. On examining the cavity, 

 apparently an old woodpecker's nest and about eight feet from the ground, 

 it was found to contain four eggs on the point of hatching. 



The species was common at the south end of Dall Island August 25-27. 



Bubo virginianus saturatus. Dusky Horned Owl. — One of the 

 fishermen reported seeing a horned owl in a thicket at the northeast end of 

 the island July 10. On visiting this locality the following day the bird was 

 not seen, but a feather was found that undoubtedly came from a bird of 

 this species. 



Ceryle alcyon caurina. Western Kingfisher. — First noted August 

 3, when a bird flew past camp. Single bird seen August 4 and again August 

 8. Probably a straggler from Dall Island, where it is common. 



Dryobates villosus sitkensis. Sitka Hairy Woodpecker. — I am 

 rather puzzled as to the exact status of this bird on the island. It was 

 rather common in the woods until the second week in June and after 

 August 1. Between these dates it was very rarely seen or heard. It may 

 have retired to more dense and ouk of the way sections to nest but no proof 

 of this was obtained. Cavities, apparently old nesting sites of some 

 woodpecker, were noted occasionally but no fresh ones were found. The 

 bird was extremely wild and no specimens were obtained but from geo- 

 graphical reasons it is probable that it is referable to the above form.
