As you expose the bones, carefully remove them using tweezers. 3. Gently break the pellet in half and continue to pull it apart into smaller pieces. 2. Use a magnifying glass to examine each bone; then, group similar bones together. 4. Use a dichotomous key to identify the different prey animals in a pellet. Examining lower jaw bones is the simplest way to identify which prey animals have been eaten by the owl. After identifying, group similar bones together. To reconstruct a skeleton, arrange all the bones from an animal on a piece of cardboard. Use white glue to attach the bones to the cardboard.
