Caruncle

We went to the Wildfowl and Wetlands Trust at Slimbridge today. We saw some black necked swans. My son asked what the red fleshy bit above the beak was called. We didn't know. A few moments later we saw a sign which told us it was called a Caruncle. It is a salt filtering gland.

According to the internet it is also an unpleasant growth that some women get in their urinary tract.

And I was just getting to like the word.
