Pig and seabird (6)
I believe the answer is:
gannet
This clue could be a double definition.
'pig' is the first definition.
The answer and definition can be both animals as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'seabird' is the second definition.
(type of seabird)
'and' acts as a link.
Can you help me to learn more?
(Other definitions for gannet that I've seen before include "Sea bird; greedy person" , "A large diving sea-bird" , "Ten nag the sea-baird" , "Proverbially greedy seabird" , "Big eater" .)
