Update: Okay so the wildlife center called and said that the birds have Trichomoniasis( canker)! The one was bad off and passed away already. The other one is not as bad and they are treating it. I feel bad, like maybe I was responsible somehow. We were ground feeding them but we always cleaned everything up, there was never anything to clean up though as they ate everything we put down within a couple hours usually. She said one of them could have picked it up someplace else and when they came here and used the bird bath it spread. She said that it is contagious through their saliva not the poop. The lady said any pigeon who gets it will die within 10 days. She said it is always fatal when they get it . I told her that I took up all the food and water. She said that is probably best. It sucks she said because she is sure the whole flock may have been exposed or probably a lot more of them since it is super contagious. If any more sick ones come here she said to try and grab them and bring them in . She said at least they can maybe treat them if it is still early on. Sadly if they don't come here she said they will likely die from it. I am hoping not all of them was exposed. Does anyone else on here know about this illness? Where does it come from? I asked her if this was common in the pigeon world and she said mostly it is pigeons and doves that get it as they feed off the ground and get into all kinds of dirty water supplies and such. She said they also have a falcon that someone else brought in who had it( definitely from eating an infected bird that had it). I looked up some research on Canker and it says that most pigeons are born with it and during times of stress it can come out and multiply and make them sick. I am confused. Can someone please clarify???
