The Wilson Bulletin— No. 48 81 



over before noon, and the earlier part of the morning seemed 

 to be the favorite time. My notes are not complete because 

 the flights were noticed a day or two before any records were 

 kept, and because I had other bird work in hand and could 

 not attend strictly to the migrators. 



The Raptores were well represented. Those which I shall 

 call Buteo were not identified with absolute certainty though I 

 should feel little hesitancy in calling them American Rough- 

 legs. They were all of the same species. The size was that 

 of the Red-shoulder or a trifle greater. The plumage above 

 seemed to be rather dark, and below the birds were whitish 

 with a dusky band varying in width and distinctness across 

 the belly. The tails all appeared like that of a young Red- 

 tail — that is, rather finely barred with dark and light. None 

 of these birds stopped, but the Sharp-shins often did so, 

 alighting among the trees and causing great disturbance 

 among the small birds. Some of these small hawks had their 

 crops vastly distended. Most of them were carefully looked 

 at through an 8-power prism glass and were found with one 

 exception to be in the brown, immature plumage. The Os- 

 preys flew low, sometimes alighting on one of the trees along 

 the bank. They varied much in the completeness of the 

 necklace. 



The Blue Jays flew just above the top of the trees, some- 

 times stopping for a moment in them. One flock stopped in 

 an oak tree to feed. Nineteen seemed to be a favorite number 

 for a flock, but they ranged from single birds to a flock of 

 thirty. The flocks trailed out sometimes being in all a hun- 

 dred yards long. These jays were absolutely silent except in 

 the cases of stray ones. 



Below I give the species of birds, with the number seen, 

 and the dates.
