Ash-breasted Antbird Myrmoborus lugubris

  • Order: Passeriformes
  • Family: Thamnophilidae
  • Polytypic: 4 subspecies
  • Authors: Thomas S. Schulenberg and Guy M. Kirwan



Forages close to the ground (rarely above 1.5 m, except during periods of unusually highwater) in dark undergrowth. Perches on slender stems or butress roots of trees. Hops deliberately from stem to stem, often reaching with legs extended to glean stems and leaf bases of leaves, and regularly hopping or flying to sally glean prey from higher surfaces up to 1 m away. Typically perches sideways on stems while peering about, often pumps tail down and raises it slowly; occasionally flicks both wings.

Social and interspecific behavior

Pairs forage alone or, less commonly, in loose association with other river island insectivores.
