Scytalopus opacus

Identification

10-10.5 cm
Male

  • Overall medium to dark grey
  • One mm wide barring of black and rusty found on rump, tips of tertials, lower flank, and undertail coverts

Female

  • Mostly rufous upperside with barring on tail and tips of tertials and coverts
  • Underside grey to lower breast
  • Flanks and undertail coverts rusty with some dusky barring and with paler mid belly

Separation of species

Paramillo Tapaculo S. canus lacks barring or brown on in the flanks, whereas Paramo Tapaculo S. opacus usually has barring on upper tail coverts, flanks and thighs. Loja Tapaculo is intermediate in plumage except that males of that species usually have white on primary coverts.
Other Tapaculos that are likely to occur near where Paramo Tapaculo is found include Ash-colored Tapaculo, Blackish Tapaculo, and Spillmann's Tapaculo.

Distribution

South America: Central Andes of Colombia to east central Ecuador.

Taxonomy

This is a monotypic species.[1]

A paper[3][4] from 2010 proposed that the Paramillo Tapaculo and the Paramo Tapaculo should be seen as separate species based on vocalizations. The split is recognised by Clements (2011)[1] and Gill and Donsker (2010)[2].

Habitat

High altitude scrub, 3000-4000 m asl.

Behaviour

Very difficult to observe as it hides in vegetation. Presumably, insects is an important source of food.

Vocalisation

Main song is similar to Loja Tapaculo except that there are one to three introductory notes. After the introductory note, it is a trill of 29-40 notes per second which usually continues for 4-12 seconds. There might be a slight slowing of the trill towards the end.
The call usually lasts around 1 second and consists of 6-7 notes that each have first and up and then a down element. The notes in the call therefore are much slower than the notes in the song.
