Pheasants!
About a month ago, I went to the RYEDALE FOLK MUSEUM, located in Hutton-le-hole, on the North Yorkshire Moors. (I recommend it, I'm a season-ticket holder..)
This involved about 20 miles of driving on C-roads, with cattle-grids, etc. There are some really scary hills, and sheer drops to the side of the road, in places..
And DEAD PHEASANTS. Hundreds of them. CARNAGE. Blood and feathers everywhere.
They don't bother to try and fly away, they just either stand there, or they run around in circles. Either way: SPLAT!
Yuck.
