Good morning, cariadau (just) 
A little show'n'tell and request for info..
I may sound a little crazy in suggesting this, but I think I may have found the wing feather of a white tailed eagle on a walk yesterday. Is that even possible? I read that they are being introduced in southern UK and Scotland and that there are a very few breeding pairs there. I also read that they have been sighted two counties away from where this feather was found
When I saw this huge feather lying on the scree at the foot of the escarpment, I couldn't quite believe it. It is 20 inches/ 51 cm long and clearly came from a larger bird than I am used to seeing anywhere in the UK. The lack of patterning, I believe, rules out a Red Kite, even if it came from a freakishly large one
So, could I be right? Could it be from a White Tailed Eagle? Or some other large visitor that I had no idea came to these parts of NE Wales?
