Buteo platypterus. Maine (Lake Umbagog). 1980. May 22. I see them nearly every day. When the wind blows fresh they rise to an immense height over the woods, breasting it on motionless wings and screaming with ap- parent delight. Their shrill ca-hoo'o'o, ca-hoo'o'o' is unmistakable. " 24. Shot one in the ordinary fall plumage. It was sit- ting on a stub over a wood path with numerous small birds dashing about it and making a great out cry. Unfortu- nately it was too badly shot to be preserved. Buteo pennsylvanicus. 1981. Maine (Lake Umbagog). (May 14). A pair at the extreme end of the Swett Cove. " 25. Shot an adult male. Irides pale brownish-yellow; tarsi and feet chrome-yellow.
