Head branch (6)
I believe the answer is:
antler
This clue could be a double definition.
'head' is the first definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'branch' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for antler that I've seen before include "Stag's horn" , "Part of a deer" , "Deer's branching horn" , "Animal's extension" , "Horn maybe of 24" .)
