The ones that are well versed in flying

How do well versed in flying

The birds have a body “designed” for flight!
Their bones are light, with spaces full of air, body tapered. The have powerful muscles to move their wings, and a breastbone like a ship’s prow to cut through the air! Their wings are specially shaped, and like the tail, have feathers of many shapes and textures, according to their job.
Bird’s flight can be “gliding” or “beating” . In the gliding flight, the bird slides through the air, wings stretched out, quite still, carried by currents of air. In the beating flight, the bird moves its wings like oars, using its tail like a rudder to change direction.
Most birds take off almost vertically from land or water, body straight and wings beating quickly.
Once in the air, it leans its body forward and the wings beat more slowly.
For landing, the movements are reversed – straightening its body and beating its wings quickly before landing.

Are there any birds which do not fly?

All birds have claws for walking and wings for flying. But many can only fly, or only walk. The reason is that they have under-developed wings or claws. For an example, Swifts have under-developed claws, but they are wonderful flyers. On the other hand, many of the large birds have under-developed wings. Splendid ostriches and humble hens can only manage a few flaps – because they have a body which is too heavy for their wings.
The ostrich is the largest bird in the word, having a height about nine feet and can often weigh in at over 300 pounds. The powerful legs it has is allowing it to reach the speeds of 40 miles an hour, outrunning the hyenas, lions, and cheetahs.

Which birds are the strongest flyers?

When migrating, the Arctic Tern covers 17,000 kilometers! And even without migrating, swallows fly up to 1000 kilometers a day. A Great Tit hen flies 100 kilometers back and forth to her nest to feed her young. As for speed, the Peregrine Falcon descends on its prey at 300 kilometers an hour, this is as fast as a Formula One racing car! A swallow can reach 200 kilometers an hour, the quail 90 kilometers and the shy turtledove around 70.

The plants which can fly

There are plants which can fly and move in the air.
These are the ones which can reproduce due to their seeds and pollen being carried on the wind.
To make the task of the wind easier and to ensure that as many new plants as possible will grow, nature has given lots of help when it comes to flying!
For an example, pollen is made up of very small grains, each with tiny little sacs of air to help it fly further.
Pollen is the male reproduction cell.
To become father a new plant, it has to come in contact with feminine cells, which it is more likely to meet some distance from its mother plant.
Some plants have seed pods which, when the become dry, they shoot their seeds away from them.
Trees such as elm, sycamore and maple produce fruit which have little propellers.

So, with their propellers, these fruits can be carried on the wind, away from the mother plant, where it can find plenty of space to grow.

Are there fish which can fly?

Yes of course – some fish have very supple pectoral fins which are very similar to birds’ wings.
These are the Flying Fish and they leap up to two peters out of the water, covering up to thirty meters in free flight gliding.
The speed they reach is a remarkable 50 kilometers an hour!
Flying fish or “Sea Swallows” live in tropical seas, but other types are also found in the southern Mediterranean.
