How the map was made
The original program computed each red dot at display time from the locality's coordinates, using its map library and one of five base maps drawn for the screen widths of the day. That library's projection — an oblique rotation of the sphere about the map's own centre, 23.7°S 47.4°W — was read from the program and checked against the graticule the same program drew into the base maps: it reproduces every grid intersection to within about a pixel. The dots here use that projection on the 1280-pixel base map, with the coordinates the discs record. Nothing was placed by hand, no modern map data was used, and a place whose coordinate is incomplete, out of range or beyond the map's edge is listed rather than guessed.
The discs carried location maps only; none shows a distribution or range.
The account, continued
Voice
Song is a series of 'jeck' -notes usually 2 to 30 sec long, but after playback up to 3 min long. Alarm call is 'ti-uit'. Other calls are a 'iht iht' and a 'birrät'. (70, 71)
Behavior
Forages close to the ground in dense undergrowth. Prefers dense scrub, including bamboo thickets, but is not confined to them.
Habitat and status
Northeast of São Paulo occurs above 800 meters in dense thickets of primary or secondary mountain forest. Frequently in bamboo (Chusquea) stands but also found above the tree line in dense scrub. South of São Paulo occurs at somewhat lower elevations (e.g. Fazenda Intervales).
Distribution
Throughout. (Serra dos Orgãos, Serra Mantiqueira, Serra Bocaina, near Campos do Jordão etc.) To 2500 meters.
Taxonomy notes
In 1997 a new species, Scytalopus iraiensis, Tall-grass Wetland Tapaculo, Macuquinho-da-varzea, was discovered in wetlands with dense brush and tall-grass meadows of the Rio Irai in the outskirts of Curitiba, Estado Parana, only about 100 km south of our area. The males of this species are similar to the males of Scytalopus speluncae, but have a black back and a grey belly and different vocalization. This species is severely threatened, because all three locations in the vicinity of Curitiba, where it has been found, are subject to habitat destruction (72).

Across the three discs
The work was published on three discs — Disc 2 in 2001, Disc 3 in 2006 and Disc 1 in 2011. Where they differ, that is a difference between historical releases, and it is never merged away. The 2011 disc is not treated as correcting the earlier ones.
