Answer 1

Correct Answer - Option 4 : Hummingbirds

The Correct Answer is Hummingbirds.

• Hummingbirds are the only birds that can fly backward.
• These Birds are the world’s smallest migrating birds. 
• The design of these bird wings differs from most other types of birds. 
• They have a unique ball and socket joint at the shoulder that allows the bird to rotate its wings 180 degrees in all directions. 
• The shape of these bird wings is long, narrow, and tapered, which allows them to move more rapidly and easily through the air. Additionally, their shoulder and elbow joints of the wing are very close to their tiny bodies, allowing their wings to tilt and pivot.
• These characteristics allow these bird to change flight directions in such a way that other birds cannot.
