Bird Cage for Keets Tiels and other small birds 22 X 17 AE 2-2217: WindyCityParrot.com, Bird Food, Parrot Food, Parrot Cages, Aviaries, Parrot Supplies,Bird Toys
anyways, dimensions are...
22” wide x 17” deep with a total height of 60”
1/2 inch bar spacing.
So, medium sized bird. Anything too small would get caught and anything too big would be cramped. With that said, my birds cages are very rarely closed. I've been looking at some love birds. They are so rad. I think that the bar spacings are about right from what I've read.
