Field notes

  • Males possess a distinctive black crown and slaty-gray plumage, while females are characterized by rufous-brown tones.
  • It was historically considered a subspecies of the Western Slaty-Antshrike (Thamnophilus punctatus) before being split based on vocal differences.
  • The species is a frequent follower of army ant swarms, opportunisticly feeding on insects flushed by the column.
  • Pairs are highly territorial and are most often seen foraging together in dense vine tangles.
  • Unlike many antbirds, they often forage higher in the vegetation, sometimes reaching the sub-canopy.
Habitat
Understory and mid-levels of humid lowland forests and mature secondary growth.
Range
Central America from Belize and Guatemala south to western Ecuador and northwestern Colombia.
