My neighbor found a young pigeon about 2 months ago. He thought he could feed it then let it go. The bird seems to be full grown but wont fly away. He is now missing most of his tail feathers. I am worried about what he will do this coming winter. Will he ever fly away? Since he is not in distress nobody will take him in as a rescue. I have been feeding him as he is not fat like the other birds in our area. Help.
