Point to barrel-shaped singer (7)
I believe the answer is:
warbler
'singer' is the definition.
(warbler is a kind of birdanimal)
'point to barrel-shaped' is the wordplay.
'point' becomes 'w' (W is an example**).
'to' says to put letters next to each other.
'shaped' indicates anagramming the letters.
'barrel' anagrammed gives 'arbler'.
'w'+'arbler'='WARBLER'
(Other definitions for warbler that I've seen before include "XWD SETTER" , "18's [BIRD]" , "A small songbird or similar singer" , "songster" .)
