I recently acquired a feral pigeon. It has warmed up to humans in the short time I've had it. I sexed it using the flipping method(see video url) and determined it was a positive female. She has started doing what I can only identify as a bow-coo however I can't find anything saying females exhibit this behaviour. She'll sit on the perch and bow her head and coo, no strutting like you'd see with a male and her crop is not puffed at all. Does this meani Klookie is actually male or is it just a mutual pair forming ritual?
