Baby owls ready to fledge?

The Great Horned Owl nestlings that were born in the tree stump have been stretching their wings and getting ready to fledge. As can be seen in the top pic, they have molted most of their fuzzy baby feathers (see some on top of head) but they are still very appealing.The mother owl, shown in the bottom pic, was perched nearby. Previously she had perched at a distance from the nest. I suspect she might be concerned for the safety of her offspring as there was a local photographer there and 2 fishermen came over to check out what he was photographing. I stayed only about 10 minutes in order to reduce disturbance. Do double-click on both of these pics to see these owls up close, especially the top pic. SeEtta
