One of the Nissen huts that we pass when we're walking the two terriers has a pair of Little Owls in residence and now a Barn Owl has decided to reside there too and the evidence, in the form of owl pellets, is on the floor almost every morning.
These are the contents of just two of the larger pellets, so despite the cold weather, the owl is hunting down and catching plenty of food.
The skull, jaw and ribs are obviously from shrews and mice and are just a fraction of the amount of bones in the furry pellet. To separate and identify all of the bones needs somebody more qualified, skilled and knowledgable than I am.
It's a cruel world out there.
