A couple of the guys at the office have had a Yellow Warbler fluttering up against their windows this week. I'm guessing that it is "fighting" off a rival, which is its own reflection of course. A male Cardinal spent hours doing this with a side mirror on our truck once.

Since my office is on the shady side and the windows less reflective, I haven't had any warbler wackiness to photograph. Instead I gave Jeff a crash course in SLR photography on the D70 and left him the camera to snap photos throughout the day. Great job Jeff!

If you look close in the eye of the second photo you'll see his reflection, along with the window frame. I did a little cropping and photoshop touchup. For shots through a window they came out really well.
