Another one of my favorites!  This Great Horned owl was sitting in a tree only about 40 feet from the main gate early in the morning.  Two of her recently fledged offspring flew off when I arrived, but this one stayed.  I photographed her for almost an hour, and during that time various song birds would see her and try to disturb her enough to fly off.  This robin was the most persistent and made several fly-by attempts to get the owl to leave but the owl just closed her eyes during the fly-bys.  The robin eventually flew off and even I left before the owl as the sun got too high in the sky and started washing out all the colours.
