The account
Description
19-19.5cm. The three sibling species of the genus Chamaeza that occur in southeastern Brazil are probably not distinguishable in the field. All are brownish above and whitish buff below with coarse streaks and speckles. All have a buffy loral spot, streaks behind the eye and cheek spot. Campanisoma has short tail with pale tip and blackish subterminal bar. Bill pale, black spot on forehead. Back olive-brown, crown more rusty. Small black speckles on white throat. Abdomen streaked. Under tail coverts buff with a few faint dark bars.

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 otus-like whistles in a series lasting about 15 sec, often with about 3 to 4 low descending 'wak wak wak' sounds at the end of song. Alarm call a 'huit' which is sometimes delivered in a series.
Behavior
Walks rail-like on the floor of dense forest and thickets.
Habitat and status
In primary and secondary woodland.
Distribution
Throughout in dry forests in the interior and in coastal humid forest, lower mountain slopes, between sea level and 1000 meters (67)

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.
