哥伦比亚角鸮

<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.
