Catcher of worms, as the dodo was? (5,4)
I believe the answer is:
early bird
'catcher of worms' is the definition.
(the early bird catches the worm)
I don't understand the remainder of the clue.
(Other definitions for early bird that I've seen before include "arriving in good time?" , "one in good time for breakfast" , "Archaeopteryx, say" , "communications satellite!" , "Worm catcher?" .)
