how do birds fly??????

Answer 1

Wings function by generating both impulsion and lift. The primary feathers (those at the tip of the wings) generate a forward thrust when the wings flap. The secondary feathers (those in the mid-part of the wing) form a cambered airfoil (in transversal section it's not flat but curved); the air flowing above the airfoil goes faster than the air flowing below it, and therefore it creates lift.
Some birds such as hummingbirds have extremely developed primary feathers; they're extremely fast flappers but cannot stop beating their wings while flying. Other birds, such as albatrosses and vultures, have extremely long or ample mid-wings and rely on lift; they´re great planners and hoverer's

Answer 2

The insides of a bird are made for the most power and the lightest weight. The biggest flying bird today is the Great Bustard. They weigh 32 pounds and are 4 feet long.

But most birds are smaller. This is the best way to fly. Another way is to use light weight `stuff' to make the bird.

Feathers are light. Birds have less bones. The bones they have are hard but thin. Some birds have bones weighing less than their feathers.

Birds have less muscle. Their bones are "glued" together . This keeps them lighter too.

The biggest muscles a bird needs are its flight muscles. These muscles need to raise the entire body weight into the air.

The eyes of the bird are very strong. Their hearing is also.

Internal Power System

Birds have a natural machine. It helps them with power in lift and take-off. The inside organs of a bird run at high speed. They need to eat "high-octane" foods.

A hummingbird would not live through the night if his heart, breathing and body temperature did not slow down. Oxygen is taken into the body through the lungs. It then passes into the blood cells. In the cells it mixes with the food to make energy.

In birds there are air sacs next to the lungs. They never run out of breath.

The heart is the key for pumping their blood. A bird's heart beats much faster than other animals. A bird's temperature is higher than mans'.

Answer 3

The simple answer is it is a combination of the shape of their feathers and their wings plus the internal structures of their body and organs.

Birds' wings are built for strength and aerodynamics. Their feathers are strong but light and when combined with other feathers, their shape helps create a difference in air pressure. This difference of air pressure helps them not only get off the ground but stay in the air with flapping and/or by allowing the wing catch a passing breeze. Different wing shapes help different species make use of flight according to their life style and according to the environment they live in. Falcons and eagles are perfectionists at soaring. Albatrosses and Gulls are gliders. They can ride the ocean winds for hours. Some species are known to glide for days on the open ocean. Quail have short round wings that are good for short and fast burts of flight - long enough for them to flee an attacker and find shelter in a tree. Owls have wide wings with feathers that have a rough edge. This cuts down on noise as they fly, making them they awesome nocturnal hunters that they are. ducks and geese have wings that are broad and pointed, which help them get off the ground fast when there's danger, yet they're long enough to maximize contact with air and lessening muscle effort when migrating.

About 70% of a bird's weight is in it's chest. All that weight is flight muscle needed for flapping! Birds have a special muscle that wraps around their shoulder and fore arm that allows the bird to raise and lower their wings with the least amount of effort. The effect is similar to an elastic band being stretched and released. Add to that hollow bones and up to seven air sacs that make use of 80% of the oxygen a bird breathes (in comparison Humans only take in 60%), you end up with a very powerful and able flier!

Body weight is definitely an important factor in flight. Heavier birds have a harder time getting off the ground. Those with the heaviest body weight have to run farther and faster to pick up enough speed to get off the ground. Others have to rely on the wind to catch their massive wings. Despite this, the birds with the biggest wings tend to be the best soarers. The heaviest bird alive today lives in Europe and weights about 140 KG.

Answer 4

Its a concept called lift. The wing is shaped just like an airplane wing or visa versa. The air travels faster over the top of the wing causing a defferance in air pressure. thus creating lift.. Simple science...

Answer 5

With wings! I myself fly on an airplane. Or at times I can fly from my living room couch.

Answer 6

the air under there wings helps to lift them up nd they flap there wings to fly

Answer 7

By flapping their wings really fast. The fact that their bones are hollow compared to ours (ours are dense, theirs have tiny air pockets in them) seems to help.

Goddess Bless!

Answer 8

They use their wings to fly.

Answer 9

with thier wings thats how i fly

Answer 10

wings feather flap
