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 characteristic hard whistle 'tuk-tuktuktuktuktu' and variations thereof. Another call is a sequence of double whistles 'tuwui....tuwui....' or 'oo-toowui' with an upward inflection on the end.
Behavior
Forages in the canopy of forest trees gleaning foliage. Not very conspicuous and relatively difficult to see.
Habitat and status
The common becard of the area in primary and mature secondary humid forest and border, open forest, especially where there are some tall trees left, gallery forest and plantations. Found also in drier inland woodland.
Distribution
Throughout the area, to 1800 meters (in the Serra Bocaina).

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.
