African runner (7)
I believe the answer is:
ostrich
'african runner' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ostrich that I've seen before include "source of showy feathers" , "The head-in-the-sand bird" , "Torch is held over large bird" , "Creature" , "World's largest bird" .)
