Dissecting owl pellets

Today we dissected Barn owl pellets.  We are studying Skellig  by David Almond in English ; the book has lots of images of birds in it and the main characters find Barn owls . Barn owls eat their prey  whole but they can't digest  the bones or fur so regurgitate them as pellets out of their beaks. We were able to find out what the Barn owls had eaten by careful dissection and identification of the bones  found.

We worked using tweezers  as the bones were  very fragile

Can you guess what it is?

Bones !

We found  many small mammal bones  belonging to voles, wood mice and  brown rats .
