Choco Screech-owl
Appearance: The Choco Screech-owl is a small owl measuring 21 cm (8.2 inches) in length. Its plumage is characterized by a striking blend of tones, designed for camouflage in the dappled light of its forested habitat. It features a round facial disc with prominent ear tufts and a distinct white throat patch. The eyes are large and yellow, aiding its night vision. The owl has a mottled appearance, with intricate patterns that blend into the bark of trees.
Habitat: The Choco Screech-owl is found in tropical and subtropical moist forests. It often inhabits: Lowland Rainforests: Dense, humid jungles in the Choco region where the climate is wet and stable. It can also be located in higher elevations within the cloud forests of the western Andes at altitudes of up to 1600 m (up to 5906 ft).
Behavior: This species is predominantly nocturnal, hunting at night and sometimes during twilight hours. Its diet consists mainly of small mammals, insects, and birds. The owl hunts from a perch, swooping down to catch prey. Choco Screech-owls are known for their characteristic and varied calls, which include a series of deep hoots and whistles, often used for communication, mating, and establishing territory.
Breeding: Breeding occurs in the rainy season, from March to June, though this can vary. They nest in tree cavities or hollow logs, where the female lays about 2 to 4 eggs. The female incubates the eggs for 26 to 30 days, with both parents involved in caring for the young after they hatch, feeding them until they are ready to fledge.
Conservation Status: The Choco Screech-owl is classified as Vulnerable on the IUCN.
Distribution
Choco Department: The Choco Screech-owl is found in the Choco Department, which provides a significant portion of its habitat. This region is known for its lush tropical and subtropical forests, characterized by high rainfall and rich biodiversity. This owl is found in lowland rainforests and mature montane forests, at elevations up to 1600 (5906 ft).
Antioquia Department: The owl is also present in certain areas of the Antioquia Department, particularly in the northwestern parts where good forest habitats exist. This may include areas in the Sierra de Abibe.
Caldas and Risaralda Departments: Portions of Caldas and Risaralda, particularly in the foothills and montane regions, may also support populations of the Chocó Screech-owl. These areas are characterized by humid forests that provide acceptable conditions for the species.

Vocalization
Hooting Calls: Their vocalization is a series of deep, resonant hoots. This call is often described as rhythmic "whoo-whoo" or "hoo-hoo," consisting of multiple hoots in succession. The calls have a two-note pattern, with the first note softer than the second, which can be more pronounced rendered as "hoo-HOO."
Soft Whistles: In addition to the characteristic hoots, the Choco Screech-owl may produce softer whistling sounds. These whistles are often used for close communication between mated pairs or when interacting with young.
Distress Calls: When threatened or alarmed, the owl may emit sharp, quick calls or distress signals. These calls are more abrupt and designed to alert other owls in the vicinity to potential dangers.
Variability: The quality and intensity of the calls can vary depending on the individual's mood or situation (e.g., during courting, when establishing territories, or while agitated).
Mating Calls: During the breeding season, males utilize their vocalizations to attract females and establish territory within their habitat.
Territorial Announcements: The distinctive hooting serves to assert presence and warn off other owls, helping maintain established territories.
Communication Among Pairs: Vocalizations are vital for maintaining contact between mated pairs, particularly when they are hunting or caring for their young.
Parent-Offspring Interaction: Softer calls help parents communicate with fledglings, providing guidance and reassurance in dense forest environments.
