Does an ostrich hide its head when it is frightened?


Ostrich
No, an ostrich doesn’t hide its head when it is frightened.  According to this old belief, the ostrich hides its head in the sand to escape danger, because it feels it is safely hidden.

What this tall bird actually does when it sights possible danger is lie flat on the ground with its long neck stretched out, thus producing a low profile.  And enemy may not be able to see the ostrich when it is in this position.  

If danger comes too near, the ostrich runs off at top speed.  Although an ostrich cannot fly, it can run as fast as 40 miles an hour, and can easily outrun most of its enemies.–Dick Rogers

How can birds perch on electric wires without getting shocked?

Birds
A bird doesn’t receive a shock when it lands on an electric wire because it lands on only one wire.  Electricity takes the path of least resistance—it flows through some materials much more easily than others.  

It is simply easier for the electricity to continue along the metal wire than it is for it to detour through the bird.  If the bird landed on two wires with different voltages, however, the electricity would flow through the bird from the wire with the higher voltage to the wire with the lower voltage, and the bird would be electrocuted.–Dick Rogers

Why do birds molt?


Molting Bird
Feathers wear out, as clothes do, and need to be replaced. The process is called “molting.”  Birds molt their feathers at least once a year, in late summer or early fall.  Feathers are made from a substance called “keratin.”  

It is basically the same material your hair is made of.  In molting, old worn feathers drop out of their sockets in a bird’s skin and new ones grow in their place.  

Some birds grow bright, new feathers for the nesting season. These birds molt twice a year.  Most birds molt just a few feathers at a time, so they are able to fly during molting periods.–Dick Rogers

Why does a peacock raise its feathers?


The handsome peacock spreads his feathers into a gorgeous fan when he courts the female, or peahen. A peacock is a bird with beautiful, rainbow-colored feathers.  Its range is really “peafowl”.

The male bird is called a peacock.  It is about as large as a turkey and has a long train or greenish feathers brilliantly spotted with bronze blue, green and gold.  A crest adorns his head.

The feather which grow from the back (and not the tail), are spread out into a gorgeous fan as the bird struts back and forth, “proud as a peacock ,” for all to see.

His majestic parade of flashing colors is actually a courtship display to charm the female, or peahen, and persuade her that he is the most handsome peacock.  The peahen is less brightly colored and has no train of feathers.

As you might imagine, the peacock’s magnificent plumage has made it a favorite parts of the world.  A peacock’s call is so loud it can be heard far away.  It sounds like a human screaming. - 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 are 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
