Percnostola arenarum
The Allpahuayo Antbird (Percnostola arenarum) is a distinctive and highly localized member of the antbird family (Thamnophilidae), endemic solely to a unique white-sand forest ecosystem in northern Peru. Measuring approximately 14-15 cm in length and weighing around 18-22 grams, this sexually dimorphic species presents a striking contrast between the sexes. Males are predominantly dark slate-gray to blackish, often with a concealed white patch on the shoulder (scapulars), and a slightly darke...
This species is an obligate specialist of low-stature, nutrient-poor white-sand (varillal) forest, primarily found on sandy, well-drained soils. It inhabits the dense undergrowth and mid-story of these unique forests at elevations typically below 200 meters.
The Allpahuayo Antbird primarily feeds on insects and other small arthropods, which it gleans from foliage and leaf litter in the forest understory.
The Allpahuayo Antbird is a diurnal, largely terrestrial to low-stratum insectivore, typically observed foraging in pairs or small family groups. They primarily hop and glean insects from dense foliage and leaf litter within 1-3 meters of the ground, meticulously searching for prey in the thick u...
The Allpahuayo Antbird boasts an exceptionally restricted geographical distribution, being endemic solely to a small region of northern Peru, specifically in the vicinity of Iquitos in the Loreto Department. Its entire known breeding and year-round range is almost entirely confined to the Allpahu...
Vulnerable
- The Allpahuayo Antbird is an "obligate specialist," meaning it can only survive in a very specific type of habitat: the nutrient-poor white-sand forests of northern Peru. - Its entire known global range covers an area smaller than many major cities, making it one of the most geographically rest...
