Mention few flight adaptations in birds.

Explanation

### Step-by-Step Solution:

1. **Streamlined Body**: Birds have a streamlined body shape which helps them reduce air resistance while flying. This shape allows air currents to flow smoothly around their bodies, enabling efficient movement through the air.

2. **Modified Forelimbs (Wings)**: The forelimbs of birds are modified into wings. These wings are covered with feathers, which are essential for flight. The structure of the wings allows birds to generate lift and maneuver in the air.

3. **Bipedal Locomotion**: Birds exhibit bipedal locomotion, meaning they walk on two legs instead of four. This adaptation reduces their overall body weight, making it easier for them to take off and fly.
