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 high fast sequence of 'zick' notes 'zikzikzikzikzikzik". Song a high, fast and two-syllabled 'wiisi wiisi wiisi wiise wiise'. Female's song is "shriller and higher pitched" (44).
Behavior
On or close the ground in humid forest, walking, hopping and climbing about. Not in bird parties.
Habitat and status
Common in the interior of dense and shady secondary and primary rain forest.
Distribution
Throughout, from Rio de Janeiro to PE Jacupiranga and-Ilha do Cardoso, up to 1000 meters.
Taxonomy notes
A common antbird of the Atlantic forest.

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.
