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
The bell-like vocalizations of this species are a characteristic feature of the southeast Brazilian rain forest. The males call a ringing, hard to describe and very loud 'boink', frequently in sequence (listen to the sound tracks). A variety of similar other sounds are also produced, such as a higher pitched metallic 'cink-cink-cink'.
Behavior
Forages for fruits in the upper and middle level of the canopy of tall and smaller trees. Sometimes occurs low in fruiting trees and then easily visible. Singing males are usually perched within the canopy of tall trees.
Breeding
Makes a stick nest formed like a cup.
Habitat and status
Common in primary and secondary mature humid forest and borders.
Distribution
Throughout. Serra do Mar, Serra Paranapiacaba (Fazenda Intervales, PE Carlos Botelho, PE Jacupiranga), Iguape, Cananeia, Ilha do Cardoso etc., Serra Mantiqueira, Serra dos Orgãos. To about 1000 meters.
Decoded from the disc's own bytes. Each part is shown under the heading the disc files it under, and the wording, spelling and punctuation are the author's.

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.
