I have many bird feeders in my backyard and I've been visited by flocks of gold finches, oregon juncos, and red-winged black birds.
My orange VK, Tomas, has been outside at the same time as the birds, but the birds know they're purrfectly safe since he can't get his 24 pounds moving toward them quickly enough to get one. I think I heard the juncos laughing at him yesterday.
