Myrmoderus ruficauda
The Scalloped Antbird (*Myrmoderus ruficauda*) is a striking passerine species endemic to the rapidly diminishing Atlantic Forest of southeastern Brazil. Measuring 14-16 cm (5.5-6.3 inches) in length and weighing 20-24 g, this medium-sized antbird is easily identified by its distinctive physical appearance. Males feature a grey head, white throat, and a prominent black breast patch, but their most notable characteristic is the intricate 'scalloped' pattern of black and white on the mantle and...
Found in humid lowland Atlantic Forest, favoring mature primary and advanced secondary growth, often near forest borders or in dense undergrowth, typically below 900-1000 meters elevation.
Primarily insectivorous, feeding on various insects (e.g., beetles, cockroaches, crickets) and other small invertebrates (e.g., spiders), mainly captured by following army ant swarms or gleaning from leaf litter.
Scalloped Antbirds are diurnal and highly secretive, spending most of their time foraging quietly on or very near the forest floor. Their primary foraging strategy involves following army ant swarms, where they opportunistically capture insects and other invertebrates flushed by the ants. They al...
The Scalloped Antbird is endemic to a fragmented range within the Atlantic Forest biome of southeastern Brazil. Its distribution spans from southern Bahia southwards through Espírito Santo, southeastern Minas Gerais, Rio de Janeiro, São Paulo, Paraná, and Santa Catarina, extending to northeastern...
