How do birds sleep while perched without falling off?
Quick Answer
Many birds have a tendon-locking system in their legs that automatically tightens their grip when they bend their knees. This lets them sleep while standing on a branch with very little effort.
The Full Story
Perching birds use a built-in locking mechanism in the tendons of the foot and leg. When they sit down on a branch, their body weight bends the joints and tightens the tendons, which makes the toes clamp around the perch. This means they can sleep without constantly using muscle power. The system is especially useful for small birds that spend long nights roosting in trees or reeds.
