Young hawk and first eaglet, for example, soaring (4)
I believe the answer is:
eyas
'young hawk' is the definition.
(I've seen this before)
'first eaglet for example soaring' is the wordplay.
'first eaglet' becomes 'e' (1st letter of 'eaglet').
'for example' becomes 'say' (I've seen this before).
'soaring' shows that the letters should be reversed in order (in a down clue, letters 'soar' up).
'say' backwards is 'yas'.
'e'+'yas'='EYAS'
'and' acts as a link.
(Other definitions for eyas that I've seen before include "Nestling falcon" , "Young falcon" , "Unfledged hawk" , "Young bird" , "young hawk" .)
