Our 40 year old Lilacine Amazon "Solomon" AKA "Beaky Guy" has been falling off his perch at night lately. He seems fine during the day however. The problem is I'm having difficulty finding an avian vet locally. Any suggestions about the falling at night would be helpful. Last night he fell off his perch around 11 pm. He was sitting on the bottom of the cage and seemed alright. About 30 minutes later I checked on him before I went to bed and he was sitting on the floor in the doorway of his cage still. I put him back on his perch and he seems fine today. Would appreciate input. Thanks
