How do bats fly in the dark?

Bat

A bat can fly in total darkness and yet never bump into anything.  The bat has a built-in radar system.  As it flies through the dark, it utters a twittering sound that is too high-pitched for us to hear.  Echoes of these sounds bounce back from any nearby object.

But listening to these echoes with its big ears, the bat is able to avoid obstacles in its path.  The bat also uses echoes to locate the mosquitoes and other insects if catches and eats.  It isn’t true that bats are blind.  They do depend mainly on their keen ears, but most bats can see in daylight. – Dick Rogers

What is a peccary?

Peccary (pronounced PECK a ree) is a wild animal that looks very much like a small, tailless pig covered with thick, bristly hair and it has a piglike snout.

Peccaries live chiefly in the forests of South America and can be found as far north as southern rooting in the ground for much of their food and eating roots, fruits and worms, as well as insects and poisonous snakes.

Peccaries avoid people if left alone.  If cornered, they can fiercely defend themselves with their sharp teeth.  With their keen ears and noses they are difficult for the hunter to find.

When disturbed, peccaries give a barklike alarm call and make a rattling sound by chattering their teeth.

Peccaries can give off a strong, evil-smelling, musky odor when excited.  For this reason, they are sometimes called “musk hogs.”

Peccaries are also known by such other names as “wild hogs” or “javelinas” (HAH vuh LEE nah).  Peccaries raised in captivity make gentle and interesting pets. – Dick Rogers

 

Why do bats fly at night?

Bat

Some birds and many animals, including bats, are adapted for living mostly at night.  Why  are some animals more active at certain times of the night or day?

The answer to this question is usually found in the kind of food the animal likes to eat.

Most bats are insect eaters.  During the day, bats sleep hanging from the ceilings of caves or buildings.

At sunset the bats leave their daytime shelter for a nighttime of hunting insects, which they catch while flying.

Bats have a built-in “radar system” that enables them to chase insects through thick forests on the darkest night without bumping into anything.

While flying, a bat makes a twittering sound that is so high-pitched that a human cannot hear it.

The sound bounce off objects and echo back to the bat’s keen ears.  Bu listening to the echoes, the bat can locate a flying insects and dodge objects in its path on its food seeking travels. – Dick Rogers

 

 

 

Is the wise old owl really wise?

Owl

Although its big, staring eyes make the own look like it is thinking very hard, it is really no smarter than other birds. 

Owls look wise because their big, staring eyes and thoughtful air give the appearance that they are thinking very hard.

Actually, the “wise old owl” is really no smarter that other birds.  In fact, geese, crows, and ravens re all smarter than the owl.

A person can recognized an owl at once by its large, broad face with a fur of feathers around the large eyes.

Unlike the eyes of most birds, the owl’s eyes are in front of its head and point forward.  But to see in another direction, the own must turn its whole head.

Persons walking around a perched owl are often amused at the way it seems in danger of twisting its head off while watching them.

The owl comes out at night to hunt for mice and other small creatures.  Its large eyes can see in the dimmest light.  But the owl does not depend on its eyes alone for hunting.

Its keen ears can hear the faintest sound and its cry startles small animals into revealing their location.  The owl’s soft feathers allow it to swoop down silently on its prey. – Dick Rogers
