What causes updrafts that allow eagles to soar?

Eagles are large birds of prey that are found in many parts of the world. They are able to soar in the sky for long periods of time without flapping their wings. This is due to a combination of factors, including their large wingspan, their lightweight bodies, and the updrafts that they seek out.

Large wingspan

Eagles have a very large wingspan, which gives them a lot of lift. This means that they can stay in the air with a minimum of effort.

Lightweight bodies

Eagles are also very lightweight birds. This is due to the fact that they have hollow bones and a high proportion of muscle to fat. This allows them to fly more easily than heavier birds.

Updrafts

Eagles seek out updrafts, which are currents of rising air. These updrafts can be created by a variety of things, such as the heating of the ground by the sun, the collision of two air masses, or the movement of air over mountains. When eagles find an updraft, they can use it to gain altitude without having to flap their wings.

Soaring is a very efficient way for eagles to travel. They can cover long distances without expending a lot of energy. This is important for eagles, who often need to travel long distances in order to find food and nesting sites.
