This is a very nice, very durable, tons of fun, 100% Superior cotton rope bird swing. The jumbo cotton bird swing measures approximately 20" in diameter. Any large bird will enjoy this nice, soft place to sleep hanging in the top of their cage. The cool part about this cotton rope swing is, the more your birds use them, the nicer they look. This is also a wonderful preening bird toy for feather pluckers. The inside is a 100% bird safe, welded ring (unlike most bird swings that are wood and easily chewed). We use over a 170 feet of bird safe superior cotton rope on this large bird toy.
