Bird found in slow lane (3)
I believe the answer is:
owl
'bird' is the definition.
(owl is a kind of bird)
'in slow lane' is the wordplay.
'in' indicates the answer is hidden within the clue.
'OWL' can be found hidden inside 'slow lane'.
'found' acts as a link.
(Other definitions for owl that I've seen before include "Bird of the 18" , "Wise person" , "Member of Parliament" , "Lear's loved a Pussy-cat" , "Bird of prey with front-facing eyes" .)
