Ah, isn't he cute ?
He probably got tired of trying to get to the fat balls, so he just fell asleep, like you do. We have flocks of collared doves in the area, so I try not to entice them into the garden too much. They do come for a drink though, but only in ones and twos, not the entire flock.
This feeder is supposed to attract the blue tits and the long-tailed tits. They come occasionally, but at the moment a family of sparrows spend many a happy hour here. They treat it like their local McDonald's.
