Answer

To differentiate the Grey Heron from the Flamingo, we can follow these steps:

### Step-by-Step Solution:

1. **Color**:
- The Grey Heron is primarily grey in color, while the Flamingo is known for its distinctive rosy pink coloration.
- **Conclusion**: They can be differentiated based on their color.

2. **Standing Position**:
- The Grey Heron typically stands on one leg with its neck sunk between its shoulders.
- In contrast, the Flamingo also stands on one leg, but it tucks the other leg beneath its body.
- **Conclusion**: Their standing positions are different, allowing for differentiation.

3. **Beak Shape**:
- The Grey Heron has a long, spear-like beak that is straight.
- The Flamingo, on the other hand, has a uniquely curved beak that is adapted for feeding upside down.
- **Conclusion**: The shape of their beaks provides another distinguishing feature.

4. **Final Conclusion**:
- Since all the features discussed (color, standing position, and beak shape) can be used to differentiate the Grey Heron from the Flamingo, the correct answer is "all of the above".

### Answer:
The Grey Heron can be differentiated from the Flamingo by color, standing position, and beak shape. Therefore, the correct answer is **all of the above**.
