Question:
what is the large mass or growth, on the eagles beak....


Replies:
If you are referring to the area by the nostrils that seems to raise above the upper mandible, I believe the structure is called an operculum. I know that is the term with pigeons, and I believe it is true with all birds having this raise on the upper mandible. I could be in error.
