Group of wild animals was curious, reportedly (5)
I believe the answer is:
pride
'group of wild animals' is the definition.
(a group of lions)
'was curious reportedly' is the wordplay.
'was curious' becomes 'pried' (to pry is to be excessively curious).
'reportedly' indicates a 'sounds like' (homophone) clue.
'pried' sounds like 'PRIDE'.
(Other definitions for pride that I've seen before include "Excessive self-esteem" , "Vanity" , "'. . . . goes before a fall'" , "group of animals" , "big cats" .)
