Where it was recorded

The discs' own checklists select Golden-chevroned Tanager at 17 localities.

Historical checklist localities on the disc's own area map — the red dots the original program drew, placed by its recovered projection. Not a range map: it shows the places whose checklists record the bird, nothing more. 1 has no usable coordinate and is listed below unplotted.

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.

Voice

Call a high upward pitched 'siii'. Song in structure and sound quality similar to the song of Thraupis cyanoptera, a 3-4 sec long sequence of about 10 whistles often repeated several times.

Behavior

Forages in pairs (breeding season) or in small groups in canopy and mid level of trees, also visits fruiting shrubs. Seldom in mixed flocks; migratory; leaves the mountains in winter and descends to the lowlands.

Breeding

Breeds in October.

Habitat and status

Locally not uncommon in primary and secondary forest and borders, in plantations, clearings with shrubs,

Distribution

Throughout in the littoral and in the serras. Apparently at sea level only in winter. To 1300 meters

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.

How that was established

Disc 1 · 2011: aux_nonzero;local_checklist_byte45_flag_1

The disc's own record fields that place the bird on its list: a non-empty entry in the species table, and the byte that marks it as selected on a local checklist.

The 2011 Disc 1 revision carries this account text unchanged from the Disc 3 release.

The work's own taxonomy

The discs carried three parallel name schemes. All three are shown as recovered; none is a modern taxonomy and none has been updated.
