When I still lived at home, we had a few bird feeders, mostly the wire tube sort. One of them had had the plastic lid chewed off by squirrels. One morning, I went out to fill the feeders and saw that this one was full of something black. When I got close, I saw that it was a starling, totally wedged head down in the tube, presumably having gone in after the last few peanuts. I thought it must be dead, trapped all night, but as I looked, it blinked...
So I had to lie the thing on the ground, and snip each wire with wirecutters, until I could open the tube up. The bird blinked a bit more, stood up, flapped a couple of times and flew off.
