Formicarius analis

Includes Panamanian Antthrush

Identification

18–19 cm

  • Upperparts brown to rufous brown (northern end of distribution)
  • Underparts grey to brown, usually a little paler than upperside
  • Black face and throat
  • Rear side of head rufous in northern populations becoming more ochre or buff or plain brown in the south east
  • Rufous under the tail

Sexes similar

Similar species

Mayan Antthrush differs in presence of a rufous band below the black throat and absence of rufous on undertail coverts.

Distribution

Central and South America
Central America: Honduras, Nicaragua, Costa Rica, Panama
South America: Colombia, Venezuela, Trinidad, the Guianas, Brazil, Ecuador, Peru, and Bolivia

Taxonomy

Mayan Antthrush was formerly included in this species.

Subspecies[1]

This is a polytypic species:
The hoffmanni Group

  • F. a. umbrosus: Caribbean slope of Honduras to western Panama
  • F. a. hoffmanni: Lowlands of south-western Costa Rica to western Panama (western Chiriquí)
  • F. a. panamensis: Eastern Panama (Choclé and Darién) and adjacent north-western Colombia
  • F. a. virescens: West base of Santa Marta Mountains (north-eastern Colombia)
  • F. a. griseoventris: Mountains of northern Colombia and north-western Venezuela in west Maracaibo basin

The analis Group

  • F. a. saturatus: Northern Colombia to north-western Venezuela; winters to Trinidad
  • F. a. connectens: Eastern Colombia east of the Andes
  • F. a. crissalis: Extreme eastern Venezuela to the Guianas and adjacent north-eastern Brazil
  • F. a. zamorae: Eastern Ecuador to north-eastern Peru and western Brazil (north of River Solimões)
  • F. a. analis: Amazonian Peru south of River Amazon to western Brazil and northern Bolivia
  • F. a. paraensis: Eastern Brazil (River Tapajós to Belém and western Maranhão)

The Hoffmanni group is sometimes split as Panamanian Antthrush. See also the information in Vocalizations, below, remembering that in Antthrushes a different song normally equals a different species.

Habitat

Tropical broadleaf forest interior ground and understory.

Behaviour

Breeding

The nest is lined with leaves and built into a cavity in a hollow branch or tree stump. The clutch consists of 2 white eggs.

Diet

The diet includes ants and other insects. They can be found following columns of army ants.

Vocalisation

Differs significantly between populations:
1. Birds from Honduras south to somewhere in northern Columbia (hoffmanni group) typically have a song of one note followed by two lower notes.
2. Birds from the rest of their South American range (analis group) have a song of one note followed by seven or so notes that ascend slightly and then descend in pitch.
