This guide uncovers the various owl species found in Oregon, offering insight into their characteristics, behaviors, and where to spot them.
Owl Species Found in Oregon
Boreal Owl
- Scientific name: Aegolius funereus
- Size: 22–27 cm (8.7–10.6 in)
- Weight: 93–170 g (3.3–6.0 oz)
- Wingspan: 50–62 cm (19.7–24.4 in)
- Time of the year: Year-round
The Boreal Owl, or Tengmalm’s Owl, is a small yet fierce owl species found in Oregon. Its haunting call is often associated with the wild and remote boreal forests where it typically resides.
The bird is cloaked in rich brown feathers, adorned with white spots, which provide excellent camouflage among the forest’s dense tree trunks. Its white facial disc, rimmed with black, houses large yellow eyes that gleam in the darkness, intimidating its prey. The Boreal Owl is generally nocturnal, most active at dusk and dawn.
Diet-wise, this owl primarily feasts on small mammals, such as voles and mice. During the breeding season, the Boreal Owl lays its eggs in natural tree cavities or old woodpecker holes, often returning to the same site year after year.
Did you know? The Boreal Owl was known for centuries as Tengmalm’s Owl after Swedish naturalist Peter Gustaf Tengmalm. It was only in the 19th century that it got its common name, the Boreal Owl, which refers to the Latin word boreas, meaning northern, and reflects its presence in northern or boreal forests.

- Time of the year: Year-round
The Northern Saw-Whet Owl is a compact species, small in stature but fierce in spirit. Its endearing face, complete with oversized round eyes and a catlike appearance, belie its formidable predatory abilities. Its name originates from the distinct “saw-whetting” call, reminiscent of a saw being sharpened on a whetting stone.
These owls inhabit dense forests, where their cryptic plumage blends in seamlessly with the tree bark. They tend to be most active at dusk and dawn, when their high-pitched calls echo through the forest. With a diet mainly consisting of small mammals, particularly mice and voles, the Northern Saw-Whet Owl is a proficient hunter despite its petite size.
