They don't seem to stay still for long enough Gary, they seem to be preoccupied with squabbling over food, like there is not enough to go around.
They turn up twice a day as far as i know, once about 10am, and then about 5pm, but there is no doubt there are there more often than that.
I have a purpose built bird bath, but they would rather use a tray on the ground, but give them time to get use to me being there and showing no threat, and maybe i will get some decent images?.
Best regards Paul
