plumage seen is thoroughly understood it is safer to regard all the 

 birds of that part of the country as of the one subspecies, calurus. 



Of the two young birds collected, the female had crop and stomach 

 filled to distention. In the partly digested mass there could be dis- 

 tinguished the remains of at least four mice and one toad. The mice 

 could be identified as Microtus mordax. The male bird had its stomach 

 filled with a mass of Micratus bones and hair. The meadow mice that 

 the young hawks had eaten must all have been fed to them by their 

 parents. While Microtus mordax was a fairly common species at that 

 point, still it is note-ftforthy that a red-tailed hawk should be sufficiently 

 agile to catch so many of them in as short a space of time as must have 

 been the case. The mice in the river bottom, where the hawks were 

 f&und, were in cover so dense that it was surprising to find a red- 

 tail there at all. The hunting of the latter, may of course, have been 

 done on the nearby mountain sides, above the denser timber, but even 

 so it seems rather remarkable that they should find so little difficulty 

 in catching these small rodents. 



Buteo swainsoni Bonaparte. Swainson Hawk 

 Seen only in the vicinity of Telegraph Creek. A number of dark 

 colored hawks were observed thereabout, some of which were identified 

 as red-tails, while others of lighter build were assumed to be of the 

 present species. Dixon shot one on June 1, but was unable to find the 

 bird until two days later, when it was unfit to preserve as a specimen. 

 One wing, one leg, and the tail were preserved (no. 39760) to make 

 identification certain. The birds seen were undoubtedly nesting 

 near-by. 



Aquila chrysaetos (Linnaeus). Golden Eagle 

 One seen at fairly close range near Telegraph Creek on June 22, 

 another at Glenora, July 7. 



Haliaeetus leucocephalus alascanus C. H. Townsend 

 Northern Bald Eagle 

 In all probability bald eagles extend inland much farther than the 

 points where we were collecting, dependent perhaps upon local condi- 

 tions, but we ourselves did not see any farther up the river than 

 Doch-da-on Creek. Here, the latter part of July, they were noted 

 on several occasions. On July 23 two were seen circling above the 

 mountain tops, at about 5000 feet altitude. Descending the Stikine 

 from Doch-da-on Creek, bald eagles were seen at various points.
