I've put up some pictures of barred owl behavior.

Please excuse the poor quality. I was sitting down for breakfast when I
spotted these two on a limb about 25 feet from the house. This was two
years ago and I had just received my first digital camera. The light was low
but I was unfamiliar with the camera's menu structure enough to get quickly
to the ISO setting. I was so excited watching them I didn't want to take
my eyes away and was afraid they might depart before I could figure out
how to set up the camera.
