Bird of prey pursuing grub, as wriggling in receptacle (5,4)
I believe the answer is:
sugar bowl
'receptacle' is the definition.
(sugar bowl is a type of receptacle)
'bird of prey pursuing grub as wriggling' is the wordplay.
'bird of prey' becomes 'owl' (owl is a kind of bird of prey).
'pursuing' says to put letters next to each other.
'wriggling' indicates anagramming the letters (letters wriggle or move about).
'grub'+'as'='grubas'
'grubas' anagrammed gives 'sugarb'.
'owl' after 'sugarb' is 'SUGAR BOWL'.
'in' acts as a link.
(Other definitions for sugar bowl that I've seen before include "Part of tea service" , "Dish for the sweetener" .)
