Tawny owl

 Ashes limestone quarry at Stanhope in Weardale ceased operations over 80 years ago and has since become a haven for wildlife. The bottom of the quarry is now a lake with a good range of wetland plant species, including mare's tail, reed mace and water mint, and is a breeding site for several dragonfly and damselfly species. The vertical cliff face hosts nesting jackdaws and sometimes its larger cavities ae occupied by less familiar bird species, like this tawny owl that I saw there a couple of weeks ago.
