Foothill Screech-owl
Appearance: The Foothill Screech Owl is a small to medium-sized owl, typically measuring about 22 to 25 cm (8.7 to 9.8 inches) in length. Its plumage is generally a mix of gray, brown, and buff, providing excellent camouflage against tree bark and foliage. It has a distinct facial disc and prominent ear tufts, adding to its characteristic appearance. The large, bright yellow eyes are adapted for night vision, enabling the owl to hunt effectively in low-light conditions.
Habitat: - The Foothill Screech Owl primarily inhabits: Premontane Woodlands and Forests: It prefers lowland and foothill forests, often found at elevations ranging from 600 to 1,800 meters above sea level. Subtropical Forests: This owl is commonly found in humid subtropical and tropical rainforests, particularly in areas with dense vegetation and tree cover.
Behavior: The Foothill Screech Owl is primarily active at night (nocturnal) but may also display some crepuscular behavior during dawn and dusk. Its diet consists mainly of small mammals, insects, and other invertebrates, which it captures from perches or by short flights. The species is known for its varied vocalizations, typically low-pitched hoots and whistles used for communication, mating, and establishing territory.
Breeding: Breeding usually occurs during the rainy season, although the exact timing can vary by location. They typically nest in tree cavities, often abandoned by other birds, where they lay approximately **2 to 4 eggs**. The female incubates the eggs for about **26 to 28 days**, and both parents help care for the chicks after they hatch.
Conservation Status: The Foothill Screech Owl is classified as Least Concern by the IUCN Red List.
Distribution
Andean Region: The Foothill Screech Owl is primarily found in the Andean foothills, where it inhabits premontane and subtropical forests. Significant populations can be observed in departments such as Antioquia, Caldas, Risaralda, and Quindío. In these areas, the owl tends to favor forested regions at elevations generally ranging from 600 to 1,800 meters above sea level.
Taxonomy

- Kingdom: Animalia
- Phylum: Chordata
- Class: Aves (Birds)
- Order: Strigiformes
- Family: Strigidae
- Genus: Megascops
- Species: Megascops roraimae
Vocalization
Hooting Calls: The primary call is a series of low-pitched hoots. It can often be described as a rhythmic "whoo-hoo" pattern. This call is gentle but can carry well through dense forest environments.
- The call might also be characterized by a two-note sequence where the first note is softer, followed by a more pronounced second note.
Whistles: Foothill Screech Owls may produce soft whistles or trills, particularly during close interactions with their mate or when communicating with young. These sounds help maintain contact in dense vegetation.
Distress Calls: When threatened or alarmed, the Foothill Screech Owl can emit sharp, quick calls designed to convey distress and ward off potential threats.
Variability: The specific pitch, rhythm, and intensity of the calls can vary between different individuals and populations. This variability may depend on the context, such as during mating or while defending territory.
Mating Calls: The hooting sounds play a crucial role during the breeding season, where males use their vocalizations to attract females and establish territory.
Territorial Announcement: Calls are important for asserting presence and warning other owls of territorial boundaries, helping to limit conflicts.
Communication Among Pairs: Vocalizations facilitate interaction between mated pairs, helping them coordinate during hunting or while caring for their young.
Contact with Young: Soothing calls can help communicate with fledglings, providing guidance and support as they develop.
