About Koepcke's screech owl
Koepcke's screech owl (Megascops koepckeae) is a species of owl native exclusively to Peru. Named in honor of the German ornithologist Maria Koepcke, this owl is a member of the Strigidae family and is considered a sister species to the tropical screech owl.
Description and Habitat
This owl measures approximately 24 cm in length. Its physical characteristics include a whitish gray facial disc, yellow eyes, and upperparts ranging from grayish brown to dark brown with streaks and barring. The underparts are grayish white with distinctive dark brown streaks. Koepcke's screech owl inhabits a variety of Peruvian landscapes. The nominate subspecies, M. k. koepckeae, is found in evergreen forests at elevations between 1,840 and 4,500 meters. The subspecies M. k. hockingi occupies dry forest and scrubby areas in intermontane valleys, typically found below 2,000 meters.
Behavior and Diet
Koepcke's screech owl is primarily nocturnal. While its diet has not been extensively studied, it is believed to consist mainly of insects, with potential inclusion of small vertebrates. The breeding phenology is largely undocumented, though breeding has been observed in February and March in south-central Peru. Nests are typically assumed to be in tree cavities, but a reported nest was found in an earthen bank.
Vocalization
The species is known for its distinctive calls. The territorial song is described as a loud, staccato series of notes that increases in pace and volume, often rendered as "ko-ko-ko-ko ka ka KA KAH!". The subspecies M. k. hockingi has a similar but longer and higher-pitched song. Aggressive vocalizations involve quieter, short hoots that vary in pitch, and pairs have been observed singing duets.
Conservation Status
The International Union for Conservation of Nature (IUCN) classifies Koepcke's screech owl as a species of Least Concern. Although its population size is undetermined, it is believed to be stable. The species demonstrates a notable ability to adapt to highly degraded habitats, provided that sufficient trees remain for roosting and nesting purposes.
