At least two of them have been exploring the area above the nest. They fly/jump 5-6 feet up and over to nearby branches. Then make clumsy pirouettes so they are facing the nest before effecting a controlled crash/dive back down. It is getting hard to spot them as they climb since they blend in with the bark.
The hawks are getting harder to find as they roam throughout the tree. One has even flown to the neighboring tree. They are up to about 20 feet of sustained, horizontal flight. I keep hoping to catch a really clean launch or landing.
The hawks are looking very adult in size. They now fly off far enough that I lose track of them. Occasionally they still strike silly poses or lose their balance a bit. Since they are molting a lot they are rather itchy.
