Scytalopus canus

Identification

10-10.5 cm
Male is all over grey, lacks black-and-brown barring on the rear that most Tapaculos show.
Female is presumably similar.
Juvenile is presumably the one shown in two images in Macaulay library as being rufous-brown on crown and with barring becoming darker towards the rear.

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.

Distribution

Two small areas in western Andes of Colombia (Antioquia).

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 scrubs. Mainly detected at 3300-3500 m asl.

Behaviour

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

Vocalisation

Main song is slower than its presumed closest relatives. It is a trill of 7-11 notes per second which usually continues for 4-12 seconds. Each note is complex giving it a churring quality. There might be a slight acceleration of the trill, but the pitch falls significantly, mainly in the start of the song.
The call usually lasts around 1 second and consists of 3-5 notes that each have first and up and then a down element. The pitch is falling during the call. The call is somewhat similar to the call of Paramo Tapaculo but the pitch is higher and the pace of notes in the call is slower.
