Thoreau writes in his journal:
A.M.—Down river to look at willows . . .
I see the fish hawk again [two or three indecipherable words] Island. As it flies low, directly over my head I see that its body is white beneath, and the white on the forward side ofVthe wings beneath, if extended across the breast,would forma regular crescent. Its wings do not form a regular curve in front, but an abrupt angle. They are loose and broad at tips . . .
P.M.—To Ledum Swamp . . .
