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 squeaking 'piz zizz zizz zizz zizz je jew jew jew'. An alternate simpler song is 'zi zi zi zi zi' (cut # 3). Call is a piercing, descending and repeated 'zieh' and a rough, rasping 'zeee' or 'shreee' (track # 6).
Behavior
Foraging in pairs in low scrub and bamboo thickets
Habitat and status
Locally common at montane forest borders and high montane scrub at the tree line.
Distribution
High mountains of northeastern Estado São Paulo and adjacent Estado Rio de Janeiro (Serra Mantiqueira, Serra dos Orgãos). 1200-2100 meters (44). Not seen at same altitudes in the coastal Serra Bocaina.
Taxonomy notes
A montane Drymophila that is fairly common in its limited range.

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.
