My husband tried that one time and he stopped doing it for the mess the birds were making. One of his favorite birds was a one eyed bird, and he dubbed him one eye.
I met a lady, walking passed her home, I noticed that she was feeding a live bird sitting on her shoulder. She fed him some mushy wet bread from a straw. So, I stopped to get nosey. I asked her about the bird. She named him, "Big mouth". As a baby, he fell from a nest and she cared for him and he flew away one day. A year later he returned! Flew on her shoulder and he chirped hard at her, so she fed him. He returned for the 2nd time when I saw this event. And that was the last time she saw him. Wow! I like watching humming birds. Here in AZ we get our snowbirds, and the humming bird is violet with black and white, very pretty! Then the Phoenix zoo stated that in the winter, snowbirds roost at their zoo and they have not choice but to feed them which means pounds of seed. Birds are amazing. If anyone says to you, "Bird Brain!" take it as a compliment!
