About Cinnamon screech owl
The cinnamon screech owl (Megascops petersoni) is a small owl species belonging to the family Strigidae. It is found in the Andean regions of Ecuador and Peru, with potential occurrences also noted in Colombia. First described in 1986, its specific epithet honors Roger Tory Peterson, a renowned figure in modern field guides. While its exact taxonomic relationships within the Megascops genus are not precisely defined, it is believed to be most closely related to the rufescent screech owl and the cloud-forest screech owl. The species is monotypic, meaning it has no recognized subspecies.
Physical Characteristics and Habitat
Adult cinnamon screech owls measure between 23 to 24 cm in length and typically weigh between 88 to 119 grams. They possess a striking warm brown facial disc bordered by blackish markings, with buffy cheeks. Their eyes are dark brown, complemented by a blue-gray bill and medium-length ear tufts. The plumage is predominantly cinnamon brown on the upperparts, featuring fine darker brown and buffy vermiculation. The wings and tail are also cinnamon, marked with brownish and blackish bars. The underside is a rich cinnamon buff, with wavy warm brown marks adorning the throat and chest. No juvenile plumage has been described in scientific literature.
This owl inhabits humid montane forests, typically found at elevations ranging from 1,650 to 2,225 meters in Ecuador and 1,700 to 2,450 meters in Peru. Its distribution is primarily along the eastern slopes of the Andes.
Behavior and Diet
Like most owls in its genus, the cinnamon screech owl is nocturnal, active primarily during the night. Information regarding its specific hunting techniques is limited, but its diet is known to consist of large arthropods and likely includes small vertebrates. Details about its breeding season, nesting habits, and clutch size remain undescribed in available records. However, it is presumed to nest in tree cavities, a common practice among screech owls.
Vocalizations and Conservation
The vocalizations of the cinnamon screech owl are distinctive. Its primary territorial song is characterized as a flat series of hoots, noted to be faster than the song of the rufescent screech owl. When displaying aggression, its call is described as a rapid sequence of 'pu-pu-pu' sounds that abruptly slows down and increases in pitch.
The International Union for Conservation of Nature (IUCN) has assessed the cinnamon screech owl as Least Concern. Despite this classification, the species faces vulnerability due to habitat loss, degradation, and forest fragmentation, which are significant threats to all species restricted to humid forest environments.
