Looks like an owl or hawk to me. Maybe an eagle? Just keep it warm and check in on it. If it's begging for food, try to give it tiny chunks of warm meat.

Tonight I found a baby bird looks like an eagle or hawk can anyone tell me what kind it is? I have it incubated right now, and the Dept. of Fish and Wildlife should be picking it up in the morning. And does anyone know of anything I can do for him? Found him outside alone in the cold screaming with no other birds or nests around. I got it to drink a lil water and he's well heated. Any additional details would be greatly appreciated ty.
