If you’re wondering whether an owl is hanging around, try listening for their hoots as dusk falls or once it’s dark out. Their calls are honestly one of the simplest ways to figure out if an owl’s nearby.
You can also spot clues like owl pellets—those weird little balls of fur and bones—on the ground under trees.
Sometimes, shining a flashlight up into the trees helps you catch the glow of their eyes. If you watch for movement or see a shape just sitting there in the branches, that’s another hint—especially if you’re near spots where mice or other small critters scurry around.
Your backyard might be home to these silent hunters, and you’d never even know unless you look for signs.
Try tuning in to the sounds and poking around places where owls like to hang out. Want to get better at spotting owls or curious about what their behavior means? Well, there’s plenty more to learn.

Top Clues That an Owl Is Nearby
If you want to figure out if an owl is in the area, pay attention to weird sounds, marks on trees, or even how other birds are acting. Owls leave behind all sorts of clues, even if you never actually see one.
Distinctive Owl Calls and Hoots
One of the best ways to figure out if an owl is close is just to listen. Owls like the great horned owl (Bubo virginianus) usually start hooting right around dusk.
Their hoots sound deep and rhythmic—kind of a “hoo-hoo-hoo”—and both males and females use them to talk to each other. Females tend to have a higher pitch.
Every owl has its own voice, in a way. The barred owl is pretty famous for that “Who cooks for you?” call. Barn owls (Tyto alba) skip the hoots and go for screeches or even hisses, which can sound downright spooky.
If it’s a calm night and you listen closely, you’ll probably hear them. That’s your best shot at catching an owl without seeing it.
Visual Signs: Roosting and Perching Habits
Owls love to sit still on shady branches or hide out in tree holes during the day. If you look up into thick trees or peek inside old woodpecker holes, you might spot one.
They usually look like big, round-headed birds with barely any neck showing. You might catch great horned or barred owls perched low enough to spot if you scan the treetops with a flashlight after dark.
Search trees near clearings or water, since owls often hunt there. If you’re patient and keep an eye on tree hollows at dusk, you might see one take off for the night.
Owl Pellets and Whitewash
Owl pellets are a dead giveaway. These are those little dark lumps of fur, feathers, and bones that owls cough up after a meal.
Check the bases of trees or under favorite perches for these pellets. If you spot them, it’s a sure sign owls have been hanging out there.
Whitewash—basically owl droppings—shows up as splatters on lower branches or the trunk. You’ll usually find it near nests or roosts.
When you see both pellets and whitewash, you’ve probably found an owl’s go-to resting spot.
Behavior of Songbirds Around Owls
Keep an eye (and ear) out for how songbirds act. When an owl is nearby, small birds often get loud and jittery because they know there’s a predator around.
If you hear a bunch of little birds chattering or spot them darting around the treetops, there’s a good chance an owl is hiding somewhere close. This happens a lot when barred owls or great horned owls show up.
Songbirds might even gang up and mob the owl—flying right at it and calling out warnings. Watching their reactions can help you find an owl without scaring it off.
Identifying Owl Presence by Species and Features
If you want to tell what kind of owl is around, pay attention to their size, ear tufts, and the shape of their faces. These features make a big difference.
Knowing when each species is active can also help you figure out where to look, whether it’s your backyard or out in the woods.
Recognizing Common Owl Species
Start with size. The Great Horned Owl is huge, with a wingspan over 4 feet. It’s tough to miss.
The Barred Owl is more medium-sized and easy to recognize by its hooting. Smaller owls like the Northern Saw-whet and Eastern Screech-Owl can easily slip by unnoticed.
Watch for special markings. The Elf Owl is tiny and lives mostly in the southwest US. Pygmy Owls are small too, but their heads are rounder.
Barn Owls, which belong to the Tytonidae family, have those heart-shaped faces and pale bodies—pretty different from other owls.
If you spot an owl flying low and slow, it could be a screech owl or maybe even a Flammulated Owl. These usually hunt near forests or open fields.
Ear Tufts and Facial Discs
Ear tufts are a big clue. The Great Horned Owl and Eastern Screech-Owl both have these tufts that stick up like little horns.
They don’t actually help with hearing, but they do make the owl’s silhouette stand out. Owls without ear tufts—like Barred Owls or Barn Owls—have round heads and smooth feathers around their faces.
Barn Owls especially stand out because of their heart-shaped facial discs. That shape helps funnel sound straight to their ears.
Facial discs matter a lot for hearing. The size and shape can be totally different from one owl to another.
For example, the Northern Hawk Owl has a broad, flat face, while the tiny Aegolius acadicus sports a tight, round disc.
Nocturnal vs. Diurnal Owls
Most owls you’ll spot are nocturnal. They hunt at night, sneaking through the darkness with sharp night vision and nearly silent wings.
Great Horned Owls and Barred Owls come alive after sunset. If you listen closely in the evening, you might catch their hoots echoing through the trees.
But not every owl waits for the dark. Some, like the Northern Hawk Owl and Burrowing Owl, are diurnal.
These daytime hunters make their moves under the sun, so you’ve got a better shot at seeing them when you’re out and about. Their habits just feel a bit less mysterious, don’t they?
Nocturnal owls usually have bigger eyes, perfect for grabbing every bit of light in the dark. Diurnal owls, on the other hand, get by with smaller eyes and their own set of quirks.
If you remember when you saw or heard an owl, it can give you a clue about what species you’re dealing with. Sometimes it’s really just about timing.
