Exceptional people in the glossy Ibises (4,5)
I believe the answer is:
rare birds
'the glossy ibises' is the definition.
Although both the answer and definition are plural nouns, I don't see how one could define the other.
'exceptional people' is the wordplay.
'exceptional' becomes 'rare' (I've seen this in another clue).
'people' becomes 'birds' (bird is a kind of person).
'rare'+'birds'='RARE BIRDS'
'in' acts as a link.
Can you help me to learn more?
(Another definition for rare birds that I've seen is " exceptional cases".)
