North African grouse may be found here (4)
I believe the answer is:
moor
I believe this is a double definition.
'north african' is the first definition.
'grouse may be found here' is the second definition.
(can find grouse on a moor)
(Other definitions for moor that I've seen before include "Secure boat with ropes" , "Heathland" , "Make a boat secure - wasteland - Mauritanian" , "Open expanse covered with heather and bracken" , "Tract of open upland" .)
