Why do birds not fall out of trees when they sleep?

Answer 1

The tendons in perching birds legs and feet are set up so that when they relax, the toes tighten down. So when a perching bird sits on a branch, its toes automatically tighten and grip the branch.
They have to flex their toes to let go.

Answer 2

Some birds have nests. Otherwise, their tiny feet have a very good grip, which they use to grip the branches on the trees, therefore staying upright while they rest.

Answer 3
