Answer

**Step-by-Step Solution:**

1. **Understanding the Relationship**: The egret bird is often seen on the back of a buffalo. This indicates a specific interaction between the two species.

2. **Analyzing the Options**: We have four statements to consider regarding why the egret is on the buffalo's back:
- A) The egret feeds on parasites on the buffalo's back.
- B) The egret feeds on insects present in the grass.
- C) The egret loves to sing while sitting on the buffalo's back.
- D) The egret rests after flying for a while.

3. **Evaluating Each Statement**:
- **Statement A**: This suggests that the egret feeds on parasites found on the buffalo. This is a common behavior seen in nature where birds help larger animals by eating pests off their bodies.
- **Statement B**: This implies that the egret is looking for insects in the grass, which does not explain its presence on the buffalo's back.
- **Statement C**: This suggests that the egret enjoys singing while on the buffalo, which is not a reason for its presence.
- **Statement D**: This states that the egret rests after flying, which does not provide a valid reason for its behavior.

4. **Conclusion**: The only statement that accurately describes the egret's behavior is Statement A: "The egret feeds on parasites on the buffalo's back." This is a mutualistic relationship where the egret benefits by getting food, and the buffalo benefits by getting rid of parasites.

**Final Answer**: The egret feeds on parasites on the buffalo's back.
