Birds have bipedal locomotion as it

Options

A. Increases rate of locomotion
B. Reduces weight
C. Spares fore limbs for flight
D. Provides more support to body

Answer

### Step-by-Step Solution:

1. **Understanding Bipedal Locomotion**:
- Bipedal locomotion refers to the ability to walk or move using two legs. In birds, this means they primarily use their hind limbs for movement.

2. **Forelimbs Modification**:
- In birds, the forelimbs have evolved and are modified into wings. This adaptation allows birds to fly, which is a crucial aspect of their survival and mobility.

3. **Hindlimbs Functionality**:
- The hind limbs of birds are not only used for walking but also serve multiple functions:
- They are equipped with scales.
- They assist in swimming in some bird species.
- They help birds clasp onto tree branches, aiding in perching and stability.

4. **Conclusion**:
- The primary reason birds exhibit bipedal locomotion is that it allows their forelimbs to be adapted for flight. This adaptation is essential for their survival, enabling them to escape predators, find food, and migrate.

5. **Final Answer**:
- Birds have bipedal locomotion as it spares the forelimbs for flight.
