We have a family of crows that I feed peanuts to and the also like the meal worms I feed to the robins. They are feeding babies now! They recognize me but are a bit Leary of my husband! If they aren’t out in the yard I whistle and they show up quickly. I believe they have trained me, not the reverse. When I am out feeding the birds, they seem to talk in a kind of gravely rumble. Have five regulars and they are here year long. When they show up and I am not out they carry on. Neighbors don’t care for them much!
