I found a baby bird July 5. I would like to know what kind of bird it is. It has a yellow breast, gray-olive back (was gray when younger), yellow under tail, and yellow tipped wings. He looks like a bandit now--black has spread over his eyes. Gray came under beak and down breast a little, but now it is white just under the beak, then a little gray, and then yellow. He eats meal worms. He is almost ready to release. If anyone has any ideas as to what species this bird is, please let me know. Thank you.
