They’ll all hang out for a good bit yet until slowly going their separate ways. I’ve been impressed with how much of a family bond they do have.

From the baby owl guide In posted to your other comment in the Food Coma post:

Do The Parents Look After The Young Owlets After They Leave The Nest?

Fledglings remain in close company for several weeks, thereafter in loose association. They often roost together in the same tree in the immediate vicinity. Adults generally roost away from the young, who react to the sight of the adults with begging calls and flights towards the adults. Fledged owls remain with parents throughout most of the summer and may be seen begging for food into October, four to five months after leaving the nest.
