Choco Screech-owl
Appearance: The Chocó Screech Owl is a small owl, typically measuring about 23 to 28 cm (9 to 11 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 help it blend into the bark of trees.
Habitat: The Chocó Screech Owl is primarily found in tropical and subtropical moist forests. It often inhabits: Lowland Rainforests: Dense, humid jungles in the Chocó region where the climate is wet and relatively stable. Montane Forests: It can also be located in higher elevations within the cloud forests of the western Andes, typically at altitudes of **200 to 1,800 meters** (656 to 5,906 feet).
Behavior: This species is predominantly nocturnal, hunting primarily at night and sometimes during twilight hours. Its diet consists mainly of small mammals, insects, and birds. The owl typically hunts from a perch, swooping down to catch prey. Chocó Screech Owls are known for their distinctive and varied calls, which include a series of deep hoots and whistles, often used for communication, mating, and establishing territory.
Breeding: Breeding generally occurs in the rainy season, from March to June, though this can vary. They usually nest in tree cavities or hollow logs, where the female lays about 2 to 4 eggs. The female incubates the eggs for approximately 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 Chocó Screech Owl is classified as **Vulnerable (VU)** on the IUCN Red List due to habitat loss and fragmentation.
Distribution
Chocó Department: The Chocó Screech Owl is primarily found in the Chocó 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.
- In Chocó, the owl is often found in lowland rainforests and mature montane forests, typically at elevations from about 200 to 1,800 meters (656 to 5,906 feet).
Antioquia Department: The owl is also present in certain areas of the Antioquia Department, particularly in the northwestern parts where suitable forest habitats exist. This may include areas within the La Tropical de la Llorona and 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 suitable conditions for the species.
Taxonomy
The Chocó Screech-owl (Megascops centralis)
- Kingdom: Animalia
- Phylum: Chordata
- Class: Aves (Birds)
- Order: Strigiformes
- Family: Strigidae
- Genus: Megascops
- Species: Megascops centralis
Vocalization
Hooting Calls: The primary vocalization is a series of deep, resonant hoots. This call is often described as rhythmic "whoo-whoo" or "hoo-hoo," typically consisting of multiple hoots in succession.
- The calls often have a two-note pattern, with the first note softer than the second, which can be more pronounced—typically rendered as "hoo-HOO."
Soft Whistles: In addition to the characteristic hoots, the Chocó 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.
