I have two Starlings nesting in the eve of my shop. I never covered the vent holes in the eves so they finally used them.
I also have a starling I rescued a couple of years ago when it fell from the nest. I actually rescued two but one left after it got wings. the other still lives in my living room. I never knew they where mocking birds. this one talks up a storm and has a vocabulary of at least 2 dozen words or sounds. his best is "what ya doin pretty bird"
