How to ID Owl Poop

Look for white droppings. Owl poop consists mostly of a white wash, much like most bird poop. This whiteness is caused by uric acid and is thought to be like urine.

See the brown additions. The brown droppings are the owl's actual poop although they don't have much here. Most of what owls can't digest comes back in the form of pellets rather than poop.

Find what looks like a good roost. Under any good roosting spot you'll find owl poop. These can be good hunting spots as well as nesting areas.

Find pellets. Pellets are different from owl poop. They are small globs of fur or feathers. Pellets also contain the prey's skeleton; sometimes it can be put completely back together. Owls swallow their prey whole but they can't digest much of what they swallow. The bones, feathers or fur that don't get digested are regurgitated as pellets. Scientists study these pellets to understand what owls are eating.
