Hello everybody!!! I need help with my domestic pigeon. Im assuming it is a male because of his behavior, I havent gotten a DNA test. When I go to his cage, he makes the territorial/mating dance and coo, and when I stand near long enough or go away, he starts calling for me with the low contact call, but when I open or put my hand near him, he gets defensive. Defensive as in backing away, flying to the other side of the cage, slapping me, and biting me. I respect his boundaries and do not put my hand in his cage with him because of this, but does anybody know why he could be acting this way?
