Hi one of the feral pigeons that lives in the alcove of my building has flat flies. I read online about a spray but although the pigeon is friendly with me I don't think he will let me spray him. I'm very fond of pigeons and of this one in particular. He hangs out on my windowsill everyday, I read the flies cause discomfort. I see him itching n I'd really like to help him but as I said he's not my pet but a feral bird with whom Ive become friends. Other than spray, Do you have any advice on how I can help him get rid of the flies? Thank you in advance for your time n any tips.
