One of the park visitors told me the owlets were about three weeks old. NOTE: Karla Bloem, an owl expert, contacted me to say that these owlets are 5 to 6 weeks old based on their feather development. (At three weeks, the wing feathers would just be starting to appear and the owlets would not be out of the nest yet.) In this photo you can see that the wing feathers have almost completely grown out. It won’t be long before the owlets are flying. I didn’t see any sign of the adult owls, but the young ones are grown up enough that they can be left on their own for extended periods of time. Perhaps the adults were off hunting. It takes a lot of food to keep three hungry youngsters satisfied.
