This cabinet contains all you need to for your avian diet explorations. Learn about ecology and the way predators interact with their prey in nature. Fun hands on project dissecting this mysterious pellet. Contains 2 extra large sanitized barn owl pellets, probes, and bone chart. What is an owl pellet: Owls eat a lot of things that they can't digest - the fur, feathers, bills, claws, teeth, skulls, and bones of their prey. Lucky for the owls, 6 to 10 hours after their meal, the indigestible bits form into a pellet in its gizzard (muscular stomach) and then move to its proventriculus (glandular stomach). From there, the owl regurgitates its meal in a compressed pellet, leaving behind handy evidence of the owl's habitat, its place in the food chain, and its predatory skills. This pellet is from a barn owl gathered from barn and forest floors. How to Examine your pellet: Carefully remove the foil wrapping from the pellet. Use the probes to dissect the pellet and extract the owl's dinner. Use the bone guide on the back of this card to identify what the owl ate. 6+ years.
