Where it was recorded

The discs' own checklists select Black-goggled Tanager at 23 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 recorded locality lies beyond the map's edge and is listed below instead.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 'tsek'. High whistle 'pseeee". Song 1 is a repetition of a 3-4 sec series of slurred whistles: whee whur whur whit phee phee; a second song is an indefinitely long series of squeals, long slurred whistles, buzzy notes and short psps in which the same note is often repeated 2-5 times (¹⁵⁹).

Behavior

Forages in the dense subcanopy and understory of forest, drops down to the ground, especially when following ant swarms. Often at forest edge in semiopen areas. Seen in pairs and small groups, sometimes in mixed species flocks. Sometimes high up in fruiting trees.

Breeding

October (São Paulo), November (Rio de Janeiro)(¹⁵⁹).

Habitat and status

Quite common in humid primary and secondary forests with dense understory.

Distribution

Throughout, also inland in Estado São Paulo. Up to 1500 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.

Which discs list this bird

Disc 2 · 2001 — in this disc's bird list
Disc 3 · 2006 — in this disc's bird list
Disc 1 · 2011 — in this disc's bird list

How that was established

Disc 2 · 2001: aux_nonzero;local_checklist_byte45_flag_1
Disc 3 · 2006: aux_nonzero;local_checklist_byte45_flag_1
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 account in the Disc 1 · 2011 revision

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.
