Product Information

How would a decline in the vole population affect barn owls in the Northwest United States? Would owls in the Southeast be similarly affected?

This comparative study kit allows students to discover the eating habits of different owls, and to learn about the various factors that can influence the food chain.

The supplied activity sheets guide students through dissecting the pellets, identifying skeletons, analyzing the diets of owls and constructing a food web.

Includes: 15 barn owl pellets each from the Northwest and Southeast, 30 dissecting needles, and an instruction guide with background information and blackline masters of student activity sheets, a dichotomous key and a bone sorting chart.

Please note: All pellets are steam sterilized and wrapped in aluminum foil.
