Niche

A medum sized nocturnal predator of rodents. Barred
owls will also eat birds, insects, and aquatic life such
as frogs and crayfish. They will hunt during daylight
hours if necessary. They are very closely related to the
endangered spotted owl. Barred owls could become quickly
endangered as well if unrestricted timber harvests are
allowed along rivers, lakes, and swamps. |

crotches. On rare occasion they will use an old hawk nest.

Behavior
and physical adaptations
|
As
with other owls, they have asymmetrical hearing for homing
in on prey. Owls have exceptional night vision. Their
feathers seem to appear ragged but their coloring is camouflage
and their ragged shape silences movement so they can fly
without making noise. The outer toe is reversible to allow
greater gripping ability. |
