Field notes

  • Males display slaty-grey plumage with a black crown and white wing-barring, whereas females are predominantly a rich rufous-brown.
  • Unlike many of its relatives, this species is strongly associated with seasonally flooded forests (varzea) and riverine gallery forests.
  • Despite its common name, the Amazonian Antshrike rarely follows army ant swarms, preferring to glean insects from foliage independently.
  • It is a frequent core member of mixed-species foraging flocks, occupying the middle to lower strata of the forest canopy.
  • Taxonomists recognize five distinct subspecies that exhibit subtle variations in plumage across the Amazon Basin.
Habitat
Humid lowland forests, particularly varzea, igapó, and swampy areas near watercourses.
Range
The Amazon Basin of South America, spanning Brazil, Peru, Colombia, Ecuador, Bolivia, and the Guianas.
