Barn Owl pellets are a wonderful tool for classrooms of all ages. The concepts of natural history, ecology and predator/prey relationships may all be found in this mysterious fur ball. Large pellets are 1-1/2 inch or greater in size, with the average size being 2-1/2 to 3-1/2 inches long. Note: The Barn Owl population is at a 10-year low and natural owl pellet supplies are limited.
