Beak membrane (4)

Ross

I believe the answer is:

cere

'beak membrane' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for cere that I've seen before include "Wax" , "Waxy covering at base of some birds' upper beak" .)

I've seen this clue in the Sydney Morning Herald.
