The account
Description
12 cm. Bill with straight culmen, "Xenops-like", appears upturned. A long white superciliary and a conspicuous white malar stripe below the brown cheek. Sepia-brown above with narrow buffy white streaks on the mantle which become broader and more cinnamon on the nape. Wings with a rusty stripe through the primaries. Chin and throat white, otherwise brownish below with dull white streaks becoming more ochraceous on the crissum. Tail rufous.
The immature plumage is less distinct in pattern.

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.

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.
