Great Horned Owl

This Great Horned Owl (Bubo virginianus) was in my front tree one morning in September of 2005, and it was NOT happy at being disturbed by a pesky photographer.

The red-eye caused by the camera's flash makes it look even angrier (and scarier) than it was, because although Great Horned Owls are an aggressive owl, they will generally only attack humans threatening their nests or young.

Great Horned Owls like to sleep in dense, shady trees during the day, and perch on high, exposed locations at night, especially when the pairs are engaged in their joint, territorial hooting. On many bright, moonlit nights, I have been awakened by the loud, deep, mournful calls of Great Horned Owls perched on my roof antennas, and although I enjoy hearing their wonderfully spooky and atmospheric calls, these large, comparatively heavy owls can leave the roof antennas askew, which causes them to get poor reception.
