Owl Pellet Dissection Lab

An owl pellet dissection lab is a good way to learn about the eating habits of birds of prey - birds such as owls that eat other animals and small birds. Owl pellet contents are great for the study of food chains which show the relationship between producers (plants) and consumers (animals that eat the plants or that eat other animals).

Owl pellets are the regurgitated remains of an owl's meal, including all the bones of the animals it ate (usually small rodents). Owls swallow their food whole (mice, voles, insects), digest the edible parts, and then expel the indigestible parts through their mouth as a pellet.

Please have your class divided into 5 groups. For this presentation, the Outdoor Environmental Education Staff need access to an area (e.g. science room or library) where each group can sit around a table.

 The lab will take approximately 2 hours to complete. A data projector and screen is also required.
