Sipia nigricauda
The Esmeraldas Antbird (Sipia nigricauda) is a striking member of the antbird family (Thamnophilidae), endemic to the humid Chocó bioregion of northwestern South America. Measuring approximately 14.5 cm (5.7 inches) in length and weighing between 20-25 grams, this species is characterized by its robust, stocky build and distinctive plumage. Males exhibit a largely dark gray to blackish coloration, contrasting sharply with rufous lower flanks and undertail coverts, and a prominently black tail...
Found primarily in the dense undergrowth of humid lowland evergreen forests and foothills, often along forest edges, secondary growth, and near streams or ravines. Occurs from near sea level up to around 900-1200 meters (3,000-4,000 feet) in elevation.
Feeds predominantly on insects and other small arthropods, which it gleans from dense foliage, bark, and leaf litter, and occasionally captures in association with army ant swarms.
The Esmeraldas Antbird is a diurnal, skulking species, typically observed alone or in pairs foraging quietly in the dense understory, often within 1-2 meters of the forest floor. It employs a methodical foraging strategy, hopping on the ground or low branches, gleaning insects and other arthropod...
