Shore bird beloved by papa (6)
I believe the answer is:
plover
'shore bird' is the definition.
(plover is a kind of shore bird)
'beloved by papa' is the wordplay.
'beloved' becomes 'lover' (someone's beloved is their partner or lover).
'by' is a charade indicator (letters next to each other).
'papa' becomes 'P' (phonetic alphabet: alpha, bravo, charlie etc.).
'lover' put after 'p' is 'PLOVER'.
(Other definitions for plover that I've seen before include "Shorebird with pointed wings" , "No Stranger on the Shore" , "Short-billed shore bird" , "Wader" , "Lapwing-like bird" .)
