Last night during the heavy rain i noticed 2 Collared Doves which was sat on the top of the feeder stand and every few minutes they would lift up a wing for about 30 sec as though they was trying to get water to the under wing or was it to just let the water to run off their wings This wemt on for about 20 Mins never seen it before most unusual but thats whats great about birds they always come up with something different Cheers Jimmy
