Best quality owl pellets for dissection and analysis. Each pellet is individually wrapped and sterilized. The study of these pellets allows students to construct food-webs, study owl diets, predict relative population densities of prey items and reconstruct skeletons! Flinn publishes a unique exercise, one of our BSCS Bio-Labs, using owl pellets. Entitled The Mysterious Yuk, this activity is listed separately under Catalog No. FB0085.
