Ok I'm giving this one to Beef as he was the first to say it 's a feather...So upgrading to a full point...
The reason is I thought it was a Magpie feather but looking at it I'm not convinced it is...
Now Out the back of mine is marshland & there is a healthy population of Marsh Harriers, so it could be from one of them...Thing is they are a tad bigger than a Crow so that clue was a bit missleading...
The only pic I've ever managed to get of said Marsh Harriers...
You'll all be glad to know that ID no 19 is not avaliable yet... So don't watch this space as it will be a new thread...
Making up since 2007, sometimes it's true...Honest...
