We just got a suction cup hummingbird feeder- more for our entertainment than nourishment for the birds. While looking on-line for them I saw a seed feeder that sticks to the window. I believe someone refered to it as "cat t.v." There is no way I'd get one of those, with my luck, the Grackles would follow me home. I'd rather they found tasty mosquitos!
