What Does an Owl Eat?

Have you ever wondered what owls eat? Owls are birds of prey, meaning they hunt and eat other animals.

Their diet consists of a wide variety of creatures, mostly small mammals. What an owl eats depends on its species, habitat, and location. Oregon, for example, is home to a diverse owl population, including Barn Owls.

Hunting for Food: Nighttime Snackers

Owls are highly adaptable and hunt whatever is available in their environment. Most commonly, their diet includes small rodents, which make up the majority of many owl species’ meals.

Barn owls, for example, primarily hunt:

  • Field voles
  • Common shrews
  • Wood mice

In some regions, these animals can make up over 75% of their diet. Barn owls may also eat rats and occasionally small birds.

But owls don’t only eat mammals. Their diet can also include:

  • Insects like moths, beetles, and crickets
  • Birds, from small sparrows to larger species
  • Reptiles and amphibians
  • Fish
  • Invertebrates like earthworms and snails

Barn owls, in particular, rely heavily on rodents like mice, voles, and shrews. Their hunting plays an important role in controlling rodent populations, which benefits local ecosystems and agriculture.

Owl’s Digestive Process: How Pellets Form

Owls cannot digest bones, fur, feathers, and certain other parts of their prey. Because barn owls swallow their food whole, they rely on a specialized organ called the gizzard.

The gizzard separates digestible material from indigestible material. The owl then regurgitates the remaining material in the form of a pellet.

Learning Through Owl Pellet Dissection

Owl pellets offer a unique, hands-on way to learn what owls eat.

When opened, each pellet reveals remains of the owl’s last meal. These natural specimens can contain bones, fur, and other clues that help identify prey species and understand hunting patterns.

By examining and identifying these bones, students can:

  • Learn about food chains
  • Identify different animal species
  • Build models of the animals the owl consumed

Owl pellet dissection turns abstract concepts into real, tangible learning experiences.

Hands-On Discovery With Owl Pellets

At Oregon Owl Pellets, we offer bulk owl pellets sourced from the Pacific Northwest. Each pellet is carefully selected for quality, making them ideal for classrooms, homeschools, and personal projects.

Dissecting pellets can reveal bones from voles, mice, and more. Whether you're a student, teacher, or nature enthusiast, it’s an engaging way to explore science beyond the textbook.

The Basics of an Owl's Diet

While many factors can influence what an owl eats—such as season, habitat, and whether they are feeding young—you should now have a solid understanding of their typical diet.
