this is the cage i use for my Bronze wing Pionus. It is a perfect cage for him and the bar spacing is 1". he is a hefty mama jamma compared to my sennie. from time to time my sennie likes to play on his cage and i really see him struggle with the distance, his little tiny feet just dont work on it. i have him in a cage with 1/2" spacing , and its 25 by 21, and he loves it. hes really immobile, but not a vegetable. its just right for him.
