Bird people, please learn me a thing!
Last year, we had a bird build their nest behind our house number thing (it tilts away from the wall).
Now there seems to be a bird sniffing around it again; anyway, there's a bird who fucks off in a hurry when we open the front door.
Should I take out last year's nest? It's pretty gross and poop-caked, but maybe this year's bird could benefit from it?
