When I was camping in the Sawtooth Mountains in Idaho, I saw a yellow rump feeding an almost adult-size immature cowbird that was out of the nest but just hopping along the branches. The cowbird was at least four times larger than the yellow rump. This morning I saw a male common yellowthroat feeding a large immature cowbird that was fluttering from branch to branch. How long do the warblers feed the cowbirds? ______________________________________________________________________ Ohio-birds mailing list, a service of the Ohio Ornithological Society.
