mutual interest in a field. This bird in the Japanese harbors plays 

 the part of scavenger, assisting the numerous gulls. It is very adept 

 at picking bits of food up from the water, devouring it afterwards 

 on the wing. 



?BUTEO BUTEO JAPONENSIS (GmelhO. 



JAPANESE BUZZARD. 



On Matsushima a Buteo was very common, which may have been 

 this species. 



AQUILA CHRYSAETOS (Linnaeus). 



GOLDEN EAGLE. 



I observed this species once on Unalaska and several times on 

 Atka, where it appears to be rather common. 



THALASSAETUS PELAGICUS (Pallas). 

 KAMCHATKAN SEA EAGLE. 



On May 26 while collecting birds in the broad valley which makes 

 up into the mountains in a southerly direction from the town of 

 Unalaska, in company with Dr. F. E. McCullouch, U. S. Navy, 

 of the Albatross, I saw a bird of this species. It sailed across 

 the valley almost directly above our heads and very low down. 

 I happened to have a Winchester repeating rifle with me at 

 the time. The bird offered an exceptionally easy shot, but unfortu- 

 nately the rifle missed (ire. On returning to the ship, Prof. J. O. 

 Snyder, of Stanford University, California, told me of a peculiar 

 eagle he had seen which I have no doubt was the same bird: he had 

 met with it about a mile away from the place where I saw it. A 

 thorough survey of these islands may show that this species, as well 

 as Haliaetus albicilla, which has been recently recorded from Una- 

 laska, are of more or less regular occurrence throughout the whole 

 group. 



I subsequently met with this bird in Kamchatka where 1 saw 

 several examples in the vicinity of Petropaulski, and in the island of 

 Sakhalin, where 1 saw two near Korsakoff. 



HALIAETUS ALBICILLA BROOKSI (Hume). 

 EASTERN GRAY SEA EAGLE. 



This bird was seen a few times in the vicinity of Petropaulski, and 

 once near Korsakoff, Sakhalin. 



Specimens of white-tailed sea eagles from eastern Asia, the Com- 

 mander Islands, and Japan are small, and are apparently identical 

 with specimens in the National Museum collection from northern 

 India, belonging to the race which has been named brooksi by Hume. 

 Probablv Aleutian and northwestern American records should be 

 referred to this form.
