Report of a snow leopard being broadcast (8)
I believe the answer is:
announce
'being broadcast' is the definition.
(thesaurus)
'report of a snow leopard' is the wordplay.
'report of' becomes 'ann' (I can't justify this - if you can you should believe this answer much more).
'a snow leopard' becomes 'ounce' (ounce is an alternative name for the snow leopard).
'ann'+'ounce'='ANNOUNCE'
(Other definitions for announce that I've seen before include "Declare, proclaim" , "Make known publicly or to an audience" , "Make known publicly with no nuance" , "Declare her weight" , "Report" .)
