It's amid some kestrels you may find these birds! (5)
I believe the answer is:
kites
'these birds' is the definition.
(kite is a kind of bird)
'it's amid some kestrels you may' is the wordplay.
'amid' means one lot of letters goes inside another.
'some' suggests taking the first letters.
'you may' becomes 'es' (I can't explain this - if you can you should believe this answer much more).
The first letter of 'kestrels' is 'k'.
'k'+'es'='kes'
'it' placed within 'kes' is 'KITES'.
'find' is the link.
Can you help me to learn more?
(Other definitions for kites that I've seen before include "More than one toy" , "Birds of prey - flying toys" , "aircraft" , "They're flown in the wind at the end of a string" , "Small hawks" .)
