Bird with a wooden leg? (5)
I believe the answer is:
stilt
I believe this clue is a double definition.
'bird' is the first definition.
(stilt is a kind of bird)
'wooden leg?' is the second definition.
(I've seen this in another clue)
'with a' is the link.
(Other definitions for stilt that I've seen before include "Supporting column driven into the ground - wading bird" , "laboured and unnatural in the past" , "Stout pole with a foot rest -- wading bird" , "Wading bird; post" , "bird found on shore" .)
