Real evidence in kids’ hands.

OBDK started with one idea: let students hold the evidence. Thirty years later, our own collection network sterilizes and ships about 400,000 barn owl pellets a year.

Trusted science education since 1996.

For decades, OBDK has supported educators and families with safe, sterilized dissection materials. Our mission is to make biological discovery approachable, meaningful, and accessible to all learners.

Millions of pellets in classrooms, nature centers and homes, with a 4.7★ rating on Amazon.

One pellet, a whole family.
Everything else we make grew from that one idea: put real evidence in kids’ hands. Free online labs, an academy for teachers, owl cards, nest boxes and a wolf center all start with a pellet.
