Flyer with current data about something resembling egg? (6)
I believe the answer is:
wigeon
'flyer' is the definition.
(something which 'flies')
'with current data about something resembling egg?' is the wordplay.
'with' becomes 'w' (abbreviation**).
'current' becomes 'i' (symbol for electric current).
'data' becomes 'gen' (I've seen this in other clues).
'about' means one lot of letters goes inside another.
'something resembling egg?' becomes 'o'.
'gen' enclosing 'o' is 'geon'.
'w'+'i'+'geon'='WIGEON'
(Other definitions for wigeon that I've seen before include "flier" , "Duck with whistling call" , "Type of duck" , "Breed of duck" , "Duck, related to mallard and teal" .)
