Question

which bird moves backwards​

Answer 1

Answer:

Hummingbirds

Hummingbirds are the only birds that can fly backwards and upside down. The design of a hummingbird's wings differs from most other types of birds. Hummingbirds have a unique ball and socket joint at the shoulder that allows the bird to rotate its wings 180 degrees in all directions.

which bird moves backwards ?

${\huge{\sf{\green{\underline {\underline {Answer }}}}}}$

Humming Bird is the only one to fly in backwards direction.

• The hummingbird has a unique muscle and wing structure that gives them a high level of flight control. You can think of a hummingbird as a miniature helicopter. Like a helicopter, the hummingbird can hover, fly right to left, left to right, diagonal, forwards, and even backwards.
• The hummingbird has the ability to rotate its wings in circles making a figure eight.
• Based on the configuration of the figure eight as shown below, the hummingbird can change directions at will. So not only does the hummingbird fly backwards, it does so with great speed and grace. In fact, they fly at a speed of up to 30 mph! If you ever observe one, you will without a doubt notice their quickness. You may also notice that their wings move so quickly that they are just a blur.
• This blurred effect is a result of their wings flapping between 15 t0 100 times per second to maintain the kind of agility to allow them to fly backwards.
