Where it was recorded

The discs' own checklists select Buff-throated Purpletuft at 3 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.

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

Usually silent. A sharp bisyllabic whistle 'si-si' thinner than the call of Euphonia chlorotica. Song "a sequence of limpid notes with short repeated motifs" (⁷⁹).

Behavior

This little bird is often very hard to see because its sits quietly in an upright position for many minutes within the canopy of a tree on thin branches resembling a fruit or a leaf. Sometimes also sits exposed at top of trees. Likes mistletoe berries.

Breeding

Nest is a very small cup resembling the nest of a hummingbird (E. O. Willis).

Habitat and status

Not uncommon in primary humid forest or mature secondary forest and forest edge. Also on single trees standing alone close to the forest border as at the Fazenda Capricornio near Ubatuba. This species qualifies as 'endangered' because of its small and severely fragmented range (¹⁰³).

Distribution

Mostly the Serra do Mar. In São Paulo state near Ubatuba (Fazenda Intervales, Rio Escuro, for example), Picinguaba. In Rio de Janeiro State near Teresopolis and old records from Cantagalo and Nova Friburgo (⁴⁰). Sea level to 1000 meters.

Decoded from the disc's own bytes. Each part is shown under the heading the disc files it under, and the wording, spelling and punctuation are the author's.

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 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 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.
