The starling shave been cleaning out this box for about 3 weeks now. He just sits up there between cleanings and sings his heart out. So far this starling has fooled us a few times. He has been a loon,an eastern phobee,a red tailed hawk and a red headed woodpecker. Quite the talents he has. He has been here a few years now and obviously has picked up on other birds sounds in the area. Kinda cool.
