It has a distinctive appearance with a tawny to rufous-brown belly, which gives it its name. The upper parts are mottled in shades of brown and gray, providing excellent camouflage in its natural habitat. The owl has a rounded facial disc, bright yellow eyes, and noticeable ear tufts that can be raised or lowered. Its underparts are streaked and barred, with a prominent white throat patch.
Habitat: The Tawny-bellied Screech Owl primarily inhabits: Tropical and Subtropical Forests: It prefers dense, humid forests, often found in lowland areas but can also occur in foothill forests. Altitude Range: It can be found at elevations ranging from about 900 to 2,200 meters (2,950 to 7,200 feet), predominantly in the Andean region and adjacent foothills.
Behavior: The Tawny-bellied Screech Owl is primarily active at night, hunting for food and communicating during the hours of darkness. Its diet consists mainly of small mammals, birds, and insects. It often hunts from a perch, swooping down to catch its prey. Known for its varied calls, it emits a series of deep hoots and whistles that serve as communication signals, particularly during the breeding season.
Breeding: The breeding season typically occurs from **March to August** in Colombia, though this may vary based on local conditions. Tawny-bellied Screech Owls usually nest in tree cavities or hollows, where the female lays about 2 to 4 eggs. The female incubates the eggs for approximately **26 to 30 days**, and both parents are involved in caring for the young after hatching.
