See for example unusual birds (5)
I believe the answer is:
geese
'birds' is the definition.
(goose is a kind of bird)
'see for example unusual' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'see' is 'ees' which is within the answer.
The remaining letters 'ge' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for geese that I've seen before include "Long-necked, migratory aquatic birds" , "Cackling creatures" , "Large birds of the duck family" , "Water birds related to ducks and swans" , "Proverbially silly birds" .)
