Great Horned Owl

Did You Know?

  • Great horned owls are fierce predators with an appetite for skunks (an unusual yet regular part of their diet), birds (hawks and waterfowl), and mammals (commonly mouse to rabbit size).
  • They use their sharp eyesight, acute hearing, and specially edged feathers for nearly silent flight to hunt and capture prey stealthily at night.
  • They are permanent residents year-round in the U.S. and do not migrate like many other bird species.
  • Adult great horned owls lack predators, though they are sometimes harassed while at roosts or nests by crows calling loudly from branch to branch.

What to watch for:

Size:

18-25" in length; 4-5' wingspan; about 3 lbs.

Appearance:

Very large with conspicuous ear tufts on the head; overall body color is mottled with reddish brown to gray or black and lighter streaked undersides; large yellow eyes with a reddish brown face bordered by black; white throat.

Nest:

In hollow cavities or broken parts (stumps) of trees and abandoned nests of squirrels, hawks, herons and crows. Also found on rocky ledges, caves, barns, and on artificial platforms.

Other signs to look or listen for:

  • Gray cylindrical pellets, which are clusters of indigestible regurgitated parts of prey such as bones feathers and fur.
  • Whitewash or liquid droppings.
  • Three to six noted hoots that are loud, consistent, and perceptible. Calling can begin in late summer and continue throughout winter of the nesting season. In the summer, the young fledglings cry loudly for food, which is often mistaken for the cry from a bobcat or fox.

Where to watch:

Great horned owls are quite common statewide and are found in a wide variety of habitats including open and secondary growth forests and agricultural and open fields. They also can be found around cliffs and suburban or urban areas.

When to watch:

They are usually most active at night but also may hunt during the day. They can be seen perched in their nests starting as early as January or February.
