My studio (a glorified shed) has these round plugs in the siding where I assume insulation was blown in. A bird has knocked one of them out and I've seen him fly inside, peck at the edge of the hole, and doing god knows what else. It's right by my head (on the other side of the wall), so I'd like to encourage the bird to take his business elsewhere, but I'm worried about doing something that will kill some baby birds or maybe a second adult bird I'm not seeing.
Any suggestions, and anyone know if it's baby bird season? (Sorry for
being very bird-ignorant) I could wait a while if it'd likely save a bird.
