Why do birds fly with wings that flap?

The reason wings flap at all is to generate thrust: lacking separate power plants, such as propellers or jet engines, bird (and bat) wings must do it all,” says Spedding. It turns out that for smaller birds it is most efficient to use intermittent flight, where they fold their wings when they are not flapping.

Why do penguins have no joints in their flippers?

There are no joints in the flipper which allows penguins to move their flippers with more power. This is especially useful when penguins dive deep and they have to battle the current and pressure of water to move further. The flipper is not very flexible either which is further important in reducing the change of injury while swimming.

Why do penguins have feathers?

Why do penguins have wings and feet?

Their wings (called “flippers” on penguins) and feet also serve a purpose. Although their flippers are not much use on land, they function like propellers when underwater, allowing them to move forward and increase their speed dramatically. Whilst swimming, their webbed feet get tucked away near the tail to be used to navigate through the water.

Why don’t penguins have bones?

Since penguins do not fly, they do not need a light, but strong, robust and not filled with air skeleton to help them submerge quickly and to stiffen their fins so they can be moved through the water more efficiently.
