This can be much more than just a swing for your bird, it can also be hung from the ceiling as used as a play area. My birds love to sleep in theirs because they feel secure with the four sides. On the four sides of stainless steel wire, it has our exclusive 1" groovy blocks with tons of colorful, bird safe fleece fabric tied in between. It has a very nice all natural, (and bird safe of course) perch that will measure approximately 1 1/4" in diameter, and it spins 180 degrees for added fun! This size measures approximately 15" overall height, by 12" wide. We recommend it for birds similar in size to afrcian greys, amazons, eclectus, small cockatoos, mini macaws and more!
