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 a soft and mournful tu u u u u u u u u' (vocalization # 1) and various 'chick' and 'chick keer' sounds.
Behavior
Singly or in pairs foraging low or at middle height in humid rain forest (down to two meters from the ground), also in canopy of trees.
Breeding
Breeds in September-October (129). Status and habitat. Rare in tall primary forest, swamp forest, tall secondary forest.
Distribution
In Estado São Paulo found near Iguape (Remold 1996 unpubl.), Fazenda Intervales (1987 119), PE Carlos Botelho, Ilha do Cardoso (Yamashita 1988, P. Matuscelli 1991 in 122). Also recorded from Rio Feio, Ipanema, Iguape (40). 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.
