Unwelcome presence! Owl just has to grin and bear the frenzy as smaller birds move in to mob it

 

This oft-seen watercolour attributed to artist John Cyril Harrison (1898-1985) is included by auction house Tennants of Leyburn, Yorkshire in their sale of British, European and Sporting Art to be held on November 11. The blue, crested and coal tits are readily identifiable, but what about the raptor? Eagle owl or long-eared owl? the catalogue has it down as the former. The pre-sale estimate is that the work, which measures 33cm x 23cm, will fetch between £200 and £300.
