BADGER

 Unfortunately most badgers I see are dead ones at the roadside.  They are mostly nocturnal unless food is in short supply.  This video from Karen Drage's garden shows just how important a sense of smell is to a badger.

They are omnivores eating a variety of food: small mammals, birds' eggs, worms, fruit and plants.  One badger can eat several hundred earthworms in a night !

My best view of a badger was  one night on holiday in Pembrokeshire in the 1990s.  It had detected a Fray Bentos meat pie tin in our dustbin.  We switched on the kitchen light and there it was, just outside the window.  Badgers' vision is not too good and the window prevented it smelling us.  All was well until somebody spoke and the badger's keen sense of hearing alerted it to our presence.
