Answer

To determine what the eggs of birds are called, let's analyze the options provided:

1. **Understanding the Types of Eggs**:
- **Polylecithal**: This term refers to eggs that contain a large amount of yolk. The prefix "poly-" means many, indicating that there are many yolk granules present.
- **Megalecithal**: This term also refers to eggs with a large amount of yolk. The prefix "mega-" means large, emphasizing the size of the yolk content.
- **Macrolecithal**: Similar to the previous terms, this also describes eggs that have a significant amount of yolk. The prefix "macro-" means large or extensive.

2. **Analyzing the Options**:
- All three terms (polylecithal, megalecithal, and macrolecithal) describe eggs with a high yolk content, which is characteristic of bird eggs.
- Since these terms are often used interchangeably in the context of bird eggs, they all refer to the same type of egg.

3. **Conclusion**:
- Given that all three terms describe the eggs of birds, the correct answer to the question is:
**(d) All of the above**.
