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
Call 'rru', song like 'duo, du -du-duo du-du-duo'. The 'du' notes are short, emphasis is on the drawn out 'duo' notes.
Behavior
Forages in the canopy of trees and bushes for fruit. Occurs singly or in flocks.
Habitat and status
Not uncommon in the edge of humid forest, open swamps, savannah with scattered trees and riverine forest.
Distribution
Throughout. In Estado São Paulo found in the coastal area at Pariquera Acu, Barra do Ribeira, Icapara, Ubatuba, Japi, Itapetininga, Cananeia, Itapeva, Rio Verde, Bananal, São Jose do Barreiro, and at many inland locations (119); there are old records from Iguape, Olimpia, Valpariso. In Estado Rio de Janeiro occurs at Itatiaia (40). Up to 800 meters

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.
