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 'sii' (159). According to Sick (121) the song is similar to that of Thraupis sayaca.
Behavior
Canopy of trees, frequents also shrubs. May be encountered in pairs, alone or in small groups.
Habitat and status
Rare in restinga forest, scrub, and gallery forest close to the coast. Moves inland in winter (119). Severely threatened by destruction of the restinga for beachfront housing. Very little habitat remains throughout the area.
Distribution
Coastal sand plain forests.
In Estado São Paulo observed at Icapara, near Sete Barras, Maruja, Cananeia (119), Ilha do Cardoso (D.F. Stotz, P.Martuscelli, G. Kirwan, unpubl.); also seen near Sao Paulo City, Cantareira, Boraceia, Ipiranga, Itararé, formerly between Santos and Peruibe in an area which is now destroyed by beachfront housing, Jureia. In Estado Rio de Janeiro there are records from Campos, near Macae, Zacarias, Saquarema, Itaborai, Rio de Janeiro (122).
Below 700 meters (133).
Taxonomy notes
Possibly conspecific with Tangara preciosa. Is considered to be "vulnerable" in the Red Data book (122). For more information see 183

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.
