Why doesn’t a bird fall off its perch when it sleeps?

Perhaps you, too, have wondered how sparrows and other perching birds can sleep on a twig or branch without falling off.  The answer is that the sleeping bird cant fall because it feet are actually “locked” on the perch.

Bird

Each of the bird’s toes are connected with a cord inside the log.  When the bird sits on a branch, the bending of the leg tightens the cord and pulls the toes around the branch.

As a result, the toes are clamped to the branch and even in sleep the bird cannot lose its hold.  The toes are loosened only when the bird awakens and stands up.

By looking at a bird’s feet we can tell a good deal about its way of life.  The strong feet of hawks and owls are provided with sharp, curved talons with which to catch their prey.

Ducks and other swimming birds have webbed feet which they use to paddle through water.

Still other birds have feet adapted for climbing, scratching, wading, running, and so on. – Dick Rogers

 

What is a sloth?

Sloth

A sloth is a curious, slow-moving animal that lives in the wet forests of South America.

The sloth has a small, roundish head and long, shaggy fur.  It spends most of its life hanging upside down, holding on to the branches of tree with its hooklike claws.

It does everything upside down.  As it hangs suspended from a limb, the sloth eats nearby leaves and buds.  It even sleep upside down.

Tiny green plants called algae often grow in the sloth’s long hair, making it hard to see in the trees.

The sloth is famous for the slowness with which it moves—its highest “speed” is only several feet per minute along a branch.

This slow-motion animal almost never comes down from its tree home,.  It can only creep along the ground with difficulty.

People sometimes use the word “slothful” describe a lazy person.  It is not hard to see why. – Dick Rogers
