A dark alba Barn Owl

Why it isn't a European Dark-brested Barn Owl (guttata)...
 
  • The pale undertail coverts and pale legs are the giveaway – they should be buff in guttata
  • pale underwing coverts – should be buff in guttata
  • white facial disc – should have extensive dark marks around the eye in guttata
  • pale grey primary tips – should be much darker grey in guttata
  • rather thin barring across primaries – should be broader in guttata and go across the whole feather


  • Taken from Birding Frontiers
