  • Male great horned owls hunt for food while females build nests.
  • Both parents feed and care for young until fledging.

In summary, Great Horned Owls exhibit remarkable cooperative behaviors when building nests as well as raising their young. Males take charge of finding appropriate locations while females gather necessary items needed for constructing nests. Both partners share duties after hatching occurs until baby birds leave home independently. Studying such intricate ecological processes allows us insight into how species interact with one another under natural conditions promoting survival success rates among families living within ecosystems worldwide.

Nest Characteristics And Ecology

Great Horned Owls are known for their large nests that they build in various locations. The nest of a Great Horned Owl is usually situated on a tree branch, and it can be as high as 60 feet from the ground. These nests are quite robust and can measure up to five feet in diameter. They often use abandoned hawk or crow nests but will also construct their own.

The female Great Horned Owl lays her eggs directly onto the nesting material, which consists of sticks and other debris found within close proximity of the nest site. Once laid, she does not add any additional lining to the nest before incubation begins. This means that young owlets have sharp twigs poking them until they grow big enough to cover themselves with feathers.

Great Horned Owls tend to reuse their nests year after year, adding new materials each breeding season. Some pairs even maintain multiple nests throughout their territories, using one or more alternately depending on weather conditions or disturbance levels at different times during the breeding cycle.
