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 a slow sequence of 'tu tu tu tu....', one call per second.
Behavior
A ground dweller in grassy areas with bushes. Usually in pairs. Sings frequently from vantage points and not too difficult to observe when vocalizing.
Habitat and status
Locally common in dry grassland, savanna and cerrado with bushy growth.
Distribution
Mostly extralimital.Itirapina is the closest location to our area from which I know that this species occurs. Might occur closer to the shore in suitable habitat. Pinto cites a male collected near Franca. To about 1000 meters (44).
Taxonomy notes
A colorful inhabitant of dry grassland, of mostly extralimital occurrence.

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.
