Encourage students to build a “Food Web of Thanks.” Start with the grain crops planted in spring. Add rodents that feed on leftover seeds. Then, connect Barn Owls as the natural pest control layer that protects future harvests.

To extend the lesson:

  • Dissect sterilized OBDK Owl Pellets to identify prey species.
  • Compare diets from different regions or seasons.
  • Discuss how human activity, irrigation, pest control, habitat changes, impacts biodiversity.

This simple web becomes a map of gratitude: every species feeding another, sustaining life through the fall.

Where it comes from

As golden fields turn to stubble and the air cools with the scent of hay, a quieter kind of harvest unfolds. Barn Owls, ghostly silhouettes of dusk, emerge from rafters and tree hollows to reap what humans have sown.

While farmers gather crops, Barn Owls gather mice, voles, and gophers. Their work is invisible but invaluable: a single family of owls can consume over 3,000 rodents in one season. These predators are not pests; they are the custodians of the fields, keeping ecosystems balanced long after tractors rest.

But the fall harvest is changing. Irrigation, pesticide use, and modern farming practices reshape what these owls can find and how they hunt. The story of their diet is also the story of our relationship with the land.
