Copied large bird, recalling detail individual omitted (8)
I believe the answer is:
emulated
'copied' is the definition.
('emulate' can be a synonym of 'copy')
'large bird recalling detail individual omitted' is the wordplay.
'large bird' becomes 'emu' (I've seen this before).
'recalling' shows that the letters should be reversed in order.
'individual' becomes 'i' (Roman numeral for one, ie individual).
'omitted' indicates named letters should be taken away.
'detail' with 'i' taken out is 'detal'.
'detal' reversed gives 'lated'.
'emu'+'lated'='EMULATED'
(Other definitions for emulated that I've seen before include "Male duet strove to equal" , "Tried hard to be as good as someone" , "Rivalled" , "Imitated" , "Tried to equal or copy" .)
