Juvenile Great Horned Owls are placed in a large building where they can learn to fly. The building has one part at an angle so they can learn to navigate around corners, which would be trees and bushes in the wild.

A juvenile, captured in flight, heads around the angle in the building to join his siblings perched on some high branches.

The PVC pipe makes an excellent landing place for the juveniles. In the wild, not all tree branches are horizontal, so this helps them learn to grab onto anything.

It is not the best photo, but this is a juvenile Great Horned in flight. Owls have a fringed front-edge on their primary (flight) feathers so they can fly silently to surprise their prey.

You can see the tufts of feathers developing, which give the Great Horned Owl its name. These feathers have nothing to do with the owl's hearing, as its ears are located on the sides of its head underneath the feathers. Isn't Thelonius Monk a handsome young owl?

The eyes of Thelonius Monk, a juvenile (and all owls) are "fixed" and always looking straight ahead. Unlike humans, who can move their eyes up, down, or sideways,the owl must turn its whole head. And no, the owl cannot turn its head all the way around.

See how the owl's head is tilted down, as he looks at the hand? This is another example of the owl not being able to simply move its eyes.

And here is the handsome, adult Thelonious Monk in December, 2007.

These are the "Frat Boys." They are both used for educational purposes and are allowed to remain together as "good buddies."
