Always a shame to find one dead like that, like finding an otter or pine marten.
No sign of what killed it ? is the reddish mark pre or post ?
The blackthorn bloomed this weekend here
and the birds are making a heck of a racket too. I put the remains of my carding into a mesh bird feeder and hung it up and the birds are already pulling out strands of it, so some of them are thinking of nesting.
