I rescue sick feral pigeons and release them when they're healthy. One in particular comes back every day with his friends (for dinner). I had two but one had PMV which affected his central nervous system so he's unable to fly. When his 'brother' flew off, I went to an animal rescue place over 40 miles away to take in a tumber pigeon who has never been allowed to fly, but trained to go up and tumble back down, to bring in racing pigeons. She's white, so easy prey. My PMV pigeon sometimes whizzes around in circles and tips his head upside down. Looks funny but probably isn't. Other than that, he's one very lucky, happy, well fed, comfortable bird, just like his little partner.
The fibro doesn't allow me to do exactly what I'd like, but I have made a childs playhouse for them to live in, with a front a side garden. Not exactly the Ritz, nor exotic, but they like it.
