Like bird with greyish appearance (5)

I believe the answer is:

ashen

I believe this is a double definition.

'like bird' is the first definition.
(I've seen this before)

'with greyish appearance' is the second definition.
(resembling ashes)

(Other definitions for ashen that I've seen before include "Having gone pale" , "White-faced" , "Deathly pale" , "lacking in colour" , "Pale (faced)" .)

I've seen this clue in The Times.
