Answer

To determine which group of animals maintains a higher constant body temperature similar to mammals, we can analyze the given options step by step.

### Step-by-Step Solution:

1. **Understanding Mammals**:

- Fishes are also cold-blooded. Similar to reptiles, they do not have the ability to maintain a constant body temperature and their temperature fluctuates with the water temperature.
- **Conclusion**: Incorrect option.

- **Option 3: Amphibians**:
- Amphibians are likewise cold-blooded. They rely on the environment to regulate their body temperature, which means they cannot maintain a constant body temperature.
- **Conclusion**: Incorrect option.

- **Option 4: Birds**:
- Birds, like mammals, are warm-blooded. They can maintain a high and constant body temperature due to their high metabolic rates, similar to mammals.
- **Conclusion**: Correct option.

3. **Final Answer**:
