Mother and wife coming round about tropical parrot (5)
I believe the answer is:
macaw
'tropical parrot' is the definition.
(I've seen this before)
'mother and wife coming round about' is the wordplay.
'mother' becomes 'ma' (ma can mean mother).
'and' says to put letters next to each other.
'wife' becomes 'w' (abbreviation).
'coming round' means one lot of letters goes inside another.
'about' becomes 'ca' (abbreviation for 'circa').
'ma'+'w'='maw'
'maw' placed around 'ca' is 'MACAW'.
(Other definitions for macaw that I've seen before include "colourful flyer" , "Long-tailed American parrot" , "Type of parrot" , "brilliant winger" , "Chattering cousin of a cockatoo" .)
