Scytalopus speluncae

(for Scytalopus notorius, see Taxonomy section)

Identification

Male dark slaty grey. Female with brown on wings and back and brown-barred flanks, but with equally dark underside.

Distribution

Mountains of south-eastern Brazil (southwestern Espírito Santo to northern Rio Grande do Sul)

Taxonomy

The taxonomy of this and related species is rather complex.

Planalto Tapaculo Scytalopus pachecoi and Rock Tapaculo Scytalopus petrophilus have been split from this species.[1][2][3]

Further, the remaining Mouse-colored Tapaculo may contain more than one species:

  • Scytalopus speluncae belongs to a lighter colored form from Serra do Espinhaço mountains in Brazil which currently does not have a name, however Espinhaço Tapaculo is proposed.
  • The dark mouse-colored form from the coastal Serra do Mar mountain range has been called Scytalopus notorius and would possibly be named Serra do Mar Tapaculo but this is the form that for a long time has been known as Mouse-colored Tapaculo and it may inherit that name.

However, notorius is no longer recognised by many authorities, and S. speluncae is regarded as monotypic.[1][4]

Habitat

Moist forest at elevations corresponding to foothills to lower mountain. In the forest limited to dense undergrowth, often with bamboo.

Behaviour

Vocal. This and similar species are often very difficult to see.
