Duck, European red one, turning up (5)
I believe the answer is:
eider
'duck' is the definition.
(eider is a kind of duck)
'european red one turning up' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'one' becomes 'i' (Roman numeral).
'turning up' says the letters should be written in reverse.
'red'+'i'='redi'
'redi' back-to-front is 'ider'.
'e'+'ider'='EIDER'
(Other definitions for eider that I've seen before include "Duck noted for down" , "Species of duck" , "Source of fine soft down" , "Duck from which down is obtained" , "Duck providing fine down" .)
