The Eastern Screech-Owl (Megascops asio) is a small, stocky owl found throughout the eastern parts of North America. These owls typically measure between 6.3 to 9.8 inches in length, with a wingspan of 18 to 24 inches. They weigh around 4 to 8 ounces, with females being slightly larger and heavier than males. The Eastern Screech-Owl exists in two primary color morphs: a gray morph and a reddish-brown morph. Both morphs feature prominent ear tufts atop their heads, which are not actual ears but help with camouflage.

Distinguishing field marks of the Eastern Screech-Owl include its small size, stocky build, yellow eyes, and the distinct patterning on its plumage. Its gray morph is predominantly gray with intricate streaks and bars, allowing it to blend seamlessly with tree bark. The reddish-brown morph exhibits a similar pattern but with various shades of reddish-brown, providing excellent camouflage among foliage. Both color morphs have a round facial disk outlined with darker feathers, enhancing their nocturnal hunting abilities.

Eastern Screech-Owls are primarily sedentary and non-migratory, often establishing territories in wooded areas, parks, and suburban neighborhoods. They prefer habitats with a mix of trees for roosting, nesting, and hunting. These adaptable owls can be found in various forest types, including deciduous forests, mixed woodlands, and even urban parks and gardens. Their call is a distinctive trill or whinny that is commonly heard during the night.

These nocturnal predators primarily feed on small mammals such as mice, voles, and shrews, but they also consume insects, small birds, and reptiles. They use their excellent hearing and night vision to locate prey while perched in trees, then silently swoop down to capture it with their sharp talons. Eastern Screech-Owls are cavity nesters, often utilizing old woodpecker holes, natural tree cavities, or nest boxes for breeding and raising their young.

Conservation efforts for Eastern Screech-Owls focus on preserving suitable habitats, providing nest boxes, and raising awareness about the importance of these owls in controlling rodent populations. Urbanization and habitat loss pose threats to these birds, making the preservation of mature trees and undisturbed wooded areas essential for their survival. Creating suitable nesting sites and minimizing human disturbances in their territories are crucial steps in ensuring the long-term stability of Eastern Screech-Owl populations.
