In many speices of birds, the males especially camp out near reflective
objects and do their macho/parading action. I have juncos that bang
on my Harely chrome parts, in the garage, back on the mtn. And, a
male cardinal that bangs on the window every year.

Hard to get them to go away, L...after breeding season, it should
diminish.

Should I post pics of my cats for you two ladies?
