Nesting season in the desert

I was out at Joshua Tree National Monument, and the Morongo Valley Preserve this weekend. Lot's of nesting birds around including these:

Young red-tailed hawk looks down at a visitor.

Stretching the wings, and building up the flight muscles. This hawk won't leave the nest until it is as big as its parents.

Great-horned owl chick still in its fluffy down feathers.
