I have wood pigeons nesting in my butterfly bush... how the hell they manage to do so when they're so big and the bush so spindly I don't know, but they are.

The nest appears to be naught but a scant platform of badly laid twigs that you can see daylight through and it's carefully positioned so that one poop from the bird sitting will get the cat crapping underneath.

The tits are still around but have chosen to nest elsewhere - their previous nest has been robbed out by the pigeons. Ever see a pigeon trying to get into a tit nest? Imagine trying to stick your head in a tennis ball... that's about it.
