Ring old English bird (6)
I believe the answer is:
hoopoe
'bird' is the definition.
(hoopoe is a kind of bird)
'ring old english' is the wordplay.
'ring' becomes 'hoop' (synonyms).
'old english' becomes 'OE'.
'hoop'+'oe'='HOOPOE'
(Other definitions for hoopoe that I've seen before include "Crested bird, pink with black and white wings" , "occasional visitor here" , "Bird with curved bill" , "Pink Eurasian bird with black and white wings and tail" , "Flier" .)
