Hi Tweets,

I am hoping someone might have an explanation for me..

I have a home office and hanging right outside my window are three bird feeders.? They are 4-5 feet from where I sit?and have been there for about a year and a half now.?

There are flocks of both chestnut backed and black capped chickadees that feed on the sunflower seeds and the suet.? There are Juncos, Towhees, Nuthatches?the occasional House Finch and a few Song Sparrows.? About a week ago, I noticed a song sparrow hopping around in a bush in kind of a circular fashion and he was fluttering his wings.? I looked up in the Bird Behavior?handbook and identified this as male courting?behavior.? Seems a bit early but it has been warm...? There was a female perched on a branch of my apple tree close by watching attentitively.

After that day, the bird began to land on the window sill and look into the house.? He would also peck on the glass a bit and fly up and down pecking on the glass.? I opened the window and the bird flew into my office about 3 feet, turned around and flew back out.? He did this 4-5 times over an hour.? I closed the window and sure enough he started fluttering at the window again.?

He feeds on the higher feeder and then flutters to the window and pecks/flutters up and down.? My windows are a mess with smeared bird saliva/suet/whatever.? He flies at the window from dawn to dusk hundreds of times per day for almost a week now.

He appears to be looking into the room when he does it and not looking at his own reflection which might be trying to drive another male bird away.? I would think the angle of light would make him not reflective at some times so this also discounts the rival theory, I think...

The poor guy must be totally worn out from this game.? I remember him doing this last year too but not quite to this extent.

Anyone help educate me on this behavior?

Thanks,
