An Eastern Screech-Owl pressed against tree bark at midday, ear tufts raised and eyes narrowed to slits, can be inches from a hiking trail and go completely unnoticed. The camouflage works in either of the species' two color forms (rusty red or soft gray, both genetically fixed and both common across most of the range), and it's often only a mob of agitated chickadees or jays scolding from nearby branches that gives the owl's position away.
The name oversells the voice. Despite it, an Eastern Screech-Owl's actual calls are soft: a descending, tremulous whinny and a low, even trill, both closer to a horse's whinny in miniature than anything resembling a screech. It's a quiet bird by owl standards, more often heard at dusk than seen at all.
One nesting habit is stranger than the rest: researchers have found screech-owls bringing live, harmless blind snakes into the nest cavity instead of eating them. The snakes survive there, burrowing through nest debris and eating insect larvae that would otherwise compete with or harm the chicks. Nestlings raised alongside a resident snake have been shown to grow faster and fledge in better condition.

How to identify
- A small, stocky owl with prominent ear tufts, occurring in both a rusty-red morph and a gray morph across the same range.
- Camouflages by pressing tight against tree bark, ear tufts raised, becoming nearly invisible during the day.
- Yellow eyes and a mottled, bark-like plumage pattern regardless of color morph.
- The name is misleading: its calls are a soft, descending whinny and an even-pitched trill, not a screech.
Voice
A soft, tremulous whinny that descends in pitch, plus a low, even trill — nothing like an actual screech.
Lore
Cherokee tradition treated the screech owl as more than background noise in the nighttime woods. Its Cherokee name, wahuhi, imitates the bird's own tremulous whinny, and its call carried real weight on the war trail: warriors read the outcome of a coming fight from the direction a screech owl's cry came from. A call from the right or left meant the fight would likely go their way; one from straight ahead or from behind was serious enough to call off the whole expedition. Owl calls in general also gave scouts a working signal, doubling as messages passed between them at night.
The screech owl kept a gentler job too, as an everyday messenger believed to carry news of things still to come. That reputation stands out against how Cherokee tradition treated night birds generally: as embodiments of the spirit world's darker half. The species held in the deepest dread was the great horned owl, whose Cherokee name, tsgili, doubled as the word for witch.

Field notes
- The red and gray color morphs are genetically determined and unrelated to age, sex, or season; both occur side by side across most of the species' range, with red birds more common in the humid Southeast.
- Roosting owls press flat against tree bark with ear tufts erect, breaking up their outline so effectively that they're often located by songbirds mobbing them rather than by direct sighting.
- Some Eastern Screech-Owls have been documented bringing live blind snakes into the nest, where the snakes burrow through debris eating insect larvae, effectively serving as a live-in pest control service that appears to improve owlet survival.
