An Aggressive Little Gnome

This Northern Pygmy-Owl at Kilchis County Park (Tillamook County, Oregon) on the tour yesterday was perhaps the most agressive one I've ever encountered. In less than a minute after we first heard it responding to my whistle, it flew across the river and descended from the canopy to the mid-level branches of the old-growth trees overhead. It paid no attention to the mobbing American Robins.
