Bird in different storey to wicket-keeper (13)
I believe the answer is:
oystercatcher
'bird' is the definition.
(oystercatcher is a kind of bird)
'different storey to wicket-keeper' is the wordplay.
'different' is an anagram indicator.
'to wicket-keeper' becomes 'catcher' (I can't justify this - if you can you should give a lot more credence to this answer).
'storey' anagrammed gives 'oyster'.
'oyster'+'catcher'='OYSTERCATCHER'
'in' is the link.
Can you help me to learn more?
(Other definitions for oystercatcher that I've seen before include "Black and white wader" , "flier with large bill" , "Carpenter, for one" , "Black-and-white wading bird with stout legs and bill" , "Pied coastal wading bird" .)
