The account

Description

12 cm. Bill decurved and slender, length depending on the age of the bird.

The male also has a post-breeding 'eclipse' plumage which resembles the female plumage but with a black back, wings and tail, and bright red legs.

The female is dull grayish green above, lighter below with dull streaks. Superciliary light yellow. Light edgings to the wing feathers. Legs reddish.

Where it was recorded

The discs' own checklists select Red-legged Honeycreeper at 2 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

Call 'tzwee', and a nasal 'tsey'.

Behavior

Forages in canopy of flowering trees in small groups or pairs. Forms part of mixed species flocks.

Breeding

Mato Grosso, October.

Habitat and status

Uncommon in primary and secondary forest, forest edge, savannah, coffee plantations, gallery forest. Migrates in conjunction with the flowering and fruiting of trees.

Distribution

In Estado São Paulo observed at Rio Claro (¹¹⁹). Also recorded from Estado Rio de Janeiro (¹²¹).

Below 1000 meters (¹³³).

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.

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.
