Wild disabled owl's and raptors will adapt to a secluded aviary,id put down a one legged or one winged bird for example but my friend has a wild diabled owl female that had a damaged wing as above and is now paired up with a captive bred male,they've nest scraped but thats it at the time being.So a wild disabled bird can have a quality of life as long as their secluded and left alone with plenty of high and low perches to scramble up on.
