Lucky you. What can I really say...you can choose to be a prick and cause that bird to flee, or you can enjoy and if your stove sends it away, that's its problem to deal with, as you each have the right to nestle into your niche.
Do you want to preserve the bird or rid it? Sounds to me like you want to preserve it
So keep taking photos and get a little humour out of your wife's reaction....like a few bird sounds are gonna wake up some kids...sorry DON'T BUY THAT!!!!!!!!! AND I'M NOT talking from inexperience
