Surprisingly, a treetop perch is a perfectly safe spot for a bird to fall asleep on. When it sits on a branch, its toes automatically curl and lock around it.?Even when it is dozing, it never loses its grip. When a bird bends its legs to sit on a branch, tendons—parts of the body that join muscles to bones—automatically pull and lock the toes into a curled position. As long as the leg remains bent, the toes stay locked.
