Epinecrophylla amazonica
The Rio Madeira Stipplethroat, *Epinecrophylla amazonica*, is a diminutive and often elusive member of the antbird family (Thamnophilidae), characteristic of the Amazonian understory. Measuring a mere 9-10 cm in length and weighing around 7-9 grams, its small stature contributes to its cryptic nature. Males typically exhibit a greyish head, olive-brown back, and two distinct white wing-bars, accented by a variably stippled to solid black throat patch that gives the species its common name. Fe...
This species primarily inhabits the dense understory and mid-story strata of humid evergreen forests, particularly favoring terra firme (unflooded) rainforests, but occasionally found in várzea (seasonally flooded) forests, up to elevations of approximately 600 meters. They prefer areas with vine...
The Rio Madeira Stipplethroat's diet consists almost exclusively of small arthropods, including various insects (e.g., beetles, ants, orthopterans, larvae) and spiders, which they primarily obtain by gleaning from foliage and small branches.
The Rio Madeira Stipplethroat is an active, diurnal bird, typically observed foraging solitarily or in pairs, though often as an integral component of mixed-species foraging flocks, especially alongside other antbirds and ovenbirds. They exhibit a characteristic "gleaning" foraging technique, met...
The Rio Madeira Stipplethroat is resident across a broad swathe of Amazonian South America, primarily within the interfluvial region bounded by the Rio Madeira and Rio Tapajós in Brazil, extending westward across parts of Peru and Bolivia. Its core distribution includes eastern Amazonas, Rondônia...
Least Concern
- The Rio Madeira Stipplethroat is part of a taxonomically complex group of antbirds, and its specific identity has been revised multiple times by ornithologists, highlighting the challenges of species differentiation in the Amazon. - Despite its small size, it's a key member of mixed-species for...
