The discs' own checklists select Lesser Grass-Finch at 1 locality.
- Itirapina ITSB
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.

Behavior
This Grass-Finch is more of a skulker than Emberizoides herbicola, foraging in high marsh grass and bushes. Does not cock tail in flight (165).
Habitat and status
Rare and probably overlooked. Is found in wetter habitat than Emberizoides herbicola, in swampy meadows and open marshes with low bushes.
Distribution
Inland Estado São Paulo. Closer to the shore found at Conde do Pinhal, Itirapina, Itapetininga (119). To 900 meters
Taxonomy notes

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.
