Animal to give birth in harbour (4)
I believe the answer is:
bear
This could be a double definition.
'animal' is the first definition.
(bear is a kind of animal)
'birth in harbour' is the second definition.
'bear' can be an answer for 'birth' (thesaurus). I am unsure of the 'in harbour' bit.
'to give' acts as a link.
Can you help me to learn more?
(Other definitions for bear that I've seen before include "eg Paddington or Yogi" , "Endure - mammal" , "Support (a weight)" , "It may be polar or grizzly" , "Relating to charged particles" .)
