So this here is a picture of the second day.

Big brother has left the nest and is humming around the area, still
depending on his mothers feeding which little one here still sits
mostly in, yet here outside the nest. He'll stay there for another
day and a night and will leave 'home' early next morning.

They still 'hang' around and are getting fed but interestingly, as
soon as the nest becomes empty, squirrels start to take it apart.

The protective 'charm' the mother seems to have placed on their
home is no longer needed...
