Silent Flight of the Owl

Still no eggs have hatched but when she flew this morning Momma Screech gave us a beautiful view of the flutings on her wing feathers. Look at the leading edge of the wing for the tooth shaped structures. It is these features, technically called fimbriae, on the primary wing feathers that allow owls to fly silently through the forest.

There were 6 eggs tonight. Sometimes when she is leaning out of the box, some of them are hidden.
