These birds are obstinate creatures, my neighbour used to feed them, and now I am pestered with them sitting on the wall outside my kitchen window, when they fly off I guarantee they'll crap all over my washing, as soon as I go to open my window they know something is coming at them, so they walk along wall to the end and wait, I blast them with the hose pipe but they soon return, I think they come back laughing at me, ha, ha missed me.
