Why Study Owl Pellets?

Owls are very often found at the top of their particular food chain and we know that they have a very significant part to play ecologically, but we still have a long way to go before we know their exact role and just how vital it is. Studying an Owl’s pellets can provide us with important information about all sorts of aspects such as prey and habitat.

What is an Owl Pellet?

Owls are carnivorous and eat a wide range of animals, including birds, voles, mice, rabbits, frogs and insects. Not having teeth, they will either eat their prey whole or tear it into large chunks with their sharp beaks. Once swallowed, the food travels down the owl’s oesophagus to the gizzard. Soft parts of the prey are then broken up by enzymes, but the hard bony components and other elements such as hair and feathers remain undigested. These are then ‘regurgitated’ or coughed up, as a pellet, before the owl can eat its next meal. Pellets are NOT droppings, as they do not pass through the intestine. They are usually quite soft to the touch and are odourless.
