Ecology Blueprints

Explore how bats and owls support healthy ecosystems through pest control, pollination, and seed dispersal—plus the challenges they face and classroom activities to bring nighttime ecology to life.

Discover how Barn Owls build their homes in a changing landscape — and how human-made nest boxes restore the harmony between nature and farming.

Discover how owl pellets reveal the hidden stories of ecosystems, connecting wildlife, farming, and science through nature’s own data.

Explore how Barn Owls adapt their diets during the fall harvest, and how irrigation, prey abundance, and farming practices shape their silent nightly hunts.

Explore how bats use their wings, echolocation, and senses to master the night—nature’s ultimate flying engineers.

Discover how bats build their upside-down homes, live in vast colonies, and engineer perfect roosts — from caves to classrooms. .

Discover the fascinating world of bats! Learn fun bat facts, explore their amazing diversity, and find classroom-friendly ways to introduce these misunderstood mammals to your students.

The Eastern Screech Owl (Megascops asio) may be no taller than a pint glass, yet its role in North American ecosystems is anything but small. This adaptable nocturnal hunter thrives in forests, orchards, city parks, and even suburban backyards — wherever trees offer shelter and safe nesting sites.

Bats are remarkable mammals — despite their small size, many live for decades, with records over 40 years. This longevity is linked to enhanced DNA repair, efficient metabolism, and strong immune systems, offering valuable insights for human health and aging research.

At OBDK, we offer a collection of posters designed to teach students about wildlife in a clear, visual, and engaging way. Each piece combines high-quality illustrations with key information, making it an ideal tool to support teachers, spark curiosity, and enrich the learning experience.

Barn owl pellets are not waste — they're carefully packed bundles of fur, bones, and insect exoskeletons, the parts of their prey that cannot be digested.

Barn owls as natural pest control and prairie protectorsSilent wings, sharp eyes, and a knack for solving mysteries — barn owls like me, Lady Eleanor Bones, are nature’s pest control team.
