アンデスコノハズク

The cloud forest screech-owl (Megascops marshalli) is a small owl in the family Strigidae endemic to the eastern slopes of the Andes in Peru and Bolivia, inhabiting cloud forest and humid montane woodland between approximately 900 and 2,200 meters elevation. Described scientifically in 1981, it belongs to the diverse Megascops screech-owl assemblage of the Americas. The species has brown, streaked cryptic plumage and small ear tufts typical of screech-owls, with a characteristic song used for territory advertisement in cloud forest habitats. It is nocturnal and insectivorous, feeding on large insects, small lizards, and other invertebrates caught in the forest understory. The cloud forest screech-owl has a restricted range on the humid eastern Andean slopes, where increasing deforestation for agriculture and coca cultivation reduces suitable habitat. Its population status is considered Least Concern given the continuing extent of Andean cloud forest in its range, though forest clearance on the eastern Andean slopes remains a long-term threat to this and many other narrowly endemic cloud forest bird species.

Colombian Screech-Owl

<em>Megascops colombianus</em>, commonly known as the Colombian screech-owl, is a small nocturnal raptor native to the Andean foothills of Colombia and Ecuador. This species inhabits tropical and subtropical montane forests, where it occupies a range of elevations typically between 1,000 and 2,000 metres above sea level. The Colombian screech-owl is assessed as Near Threatened by the IUCN, reflecting ongoing habitat loss driven by agricultural expansion and deforestation within its restricted range. Like other members of the genus <em>Megascops</em>, this owl is presumed to be an insectivore and opportunistic predator of small vertebrates, hunting under cover of darkness using acute hearing and silent flight. Its cryptic plumage provides effective camouflage against tree bark, making individuals difficult to detect. The species is poorly known, with limited published data on its breeding biology, population size, and precise ecological requirements. Research indicates that ongoing forest fragmentation in the Colombian Andes represents the primary threat to long-term population viability. Biological traits of this species remain poorly documented in the scientific literature.
