Sounds like what used to be called "Empty Nest Syndrome."
Empty Nest Syndrome is named for how scientists thought the mother bird feels when her baby birds fly away.
I don't know about all birds, but when eaglettes get about the age of teenagers in people years, the mother eagle begins to pull the grass and other soft padding from the nest so the baby birds wind up very uncomfortable on the sticks and thorns of the nest. It is to make them uncomfortable enough to will leave the nest and fly away.

The lesson of that seems to be if we want our children to soar like eagles, we have to not only allow them to fly, we may have to nudge them out of the nest.
Sonds like a good thing for all.
