Bird caught next to Peak District river (8,4)
I believe the answer is:
collared dove
'bird' is the definition.
(I've seen this before)
'caught next to peak district river' is the wordplay.
I cannot really see how this works, but
'caught' could be 'collared' (I've seen this before) and 'collared' is found within the answer.
'river' could be 'dove' (River Dove in the Midlands) and 'dove' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for collared dove that I've seen before include "Flier" , "Rival to the 5 4" , "Bird" .)
