Biology students learn about the flow of energy through dissection of owl pellets -- 4.3.17

Students in Dianna Cooper’s Biology class had the opportunity to dissect owl pellets to help with their understanding of energy flow through food webs as part of their Ecology unit. Owl pellets are masses of bone, teeth, hair, feathers, and exoskeletons of various animals preyed upon by raptors, or birds of prey. Pellets are produced and regurgitated not only by owls, but by hawks, eagles, and other raptors that swallow their prey whole or in small pieces. Owls feed early in the evening and regurgitate a single pellet approximately 20 hours after eating.
