[edit] Identification

12-13 cm (4¾-5 in). An antwren with a longer tail than all other related species.

  • Black crown and nape
  • Long pale grey to white supercilium
  • Black loral stripe and postocular stripe
  • Dark grey upperparts with variable black patches with many white feather edges
  • Black wings with two white wing-bands
  • Black tail with white tips
  • Grey throat and underparts with white central belly and white underwing-coverts

Females have white crown spots, a buff-tinged neck side, light buff breast and sides and smaller tail spots.

[edit] Variations

  • female kathleenae has greyer upperparts and pale grey (rather than light buff) breast and sides.

[edit] Distribution

South America: found in Northern Brazil, west-central Guyana, and southern Venezuela.
A restricted-range species but locally fairly common in its small range.

[edit] Taxonomy

[edit] Subspecies

Two subspecies recognized[1]:

  • H. r. kathleenae in Tepuis of southwest Venezuela and adjacent Brazil (northern Amazonas)
  • H. r. roraimae in Tepuis of southeast Venezuela, adjacent northern Brazil (northern Roraima) and west-central Guyana

[edit] Habitat

Moist montanes. Canopy and subcanopy of humid to wet, evergreen forest and forest borders, at 700–2000 m. Occupies tall forest growing on richer soils on lower and mid-slopes of tepuis; also stunted forest dominated by melastome (Melastoma) on poorer soils near the tops, and occurs regularly at ecotones between latter habitat and brushy savanna at higher elevations.

[edit] Behaviour

[edit] Diet

Feeds on insects, probably also spiders.
Forages in canopy but as low as 3 m in small saplings. Often with mixed-species flocks of other insect-eating species like Redstarts and Tanagers.

[edit] Breeding

No information.

[edit] Movements

Presumably a resident species.
