チョコオタテドリ

The Choco Tapaculo (Scytalopus chocoensis) is a small, secretive bird in the family Rhinocryptidae, endemic to the Chocó biogeographic region of the Pacific slope of Colombia and northwestern Ecuador. Tapaculos are among the most cryptic and difficult-to-observe birds in the Neotropics, living in dense undergrowth close to the forest floor and rarely venturing into the open. They are typically dark grey to blackish overall with barred or brownish flanks, and are most reliably identified by their loud, distinctive territorial songs — a series of repeated notes that carry well through dense vegetation. The Choco Tapaculo inhabits humid foothill and montane forest understory, particularly in areas with dense shrubbery, bamboo, and moss-covered logs on the forest floor, at elevations roughly between 500 and 2,000 metres. It forages terrestrially among leaf litter for small invertebrates including beetles, ants, and other arthropods. The IUCN classifies this species as Least Concern given its occurrence across a reasonably wide elevational band in relatively intact Andean foothills. The ongoing decline of Chocó forest at lower elevations, however, means that foothill-specialised species like this tapaculo face progressive habitat loss and upslope range compression.
