The Barn Owl. An Introduction to Owl Pellet Labs. Describes the habitat and life-cycle of the Barn Owl. Computer animation is used to show the adaptations which allow the owl to find prey in darkness and process the prey into pellets. The final portion of this video is an overview of classroom techniques with owl pellets, including dissection and identification of prey and their skeletal parts. 15 minutes.
Provide your classroom with an unforgettable, hands-on lesson on ecology and the food chain. Your students will dissect owl pellets to study the skeletal remains of the raptor's prey and, using a dichotomous key, identify the species consumed. Also construct a rodent skeleton from the recovered skeletal prey. With their findings, students will construct a food web, compiling a summary of the owl's diet in order to estimate the diversity of the prey available in the ecosystem.
