Where it was recorded

The discs' own checklists select Green-barred Woodpecker at 14 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

Most common call a repeated 'wheeo wheeo wheeo. . . .' (vocalizations # 1-3), a 'kwik kwik kwik kwik . . ', 'ca wik ca wik . . ' and similar calls recalling vocalizations of the Northern Flicker.

Behavior

Occurs mostly singly. Arboreal and terrestrial (leaps in long hops), but needs trees and forages in the mid and higher level of trees probing and gleaning. Sometimes leaps like a jay through the crown of a tree.

Breeding

Starting in August-September. Nest in a dead tree.

Habitat and status

Common in forests and forest borders, scrub, open woodland, savannah, up to 2000 meters

Distribution

Throughout.

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

How that was established

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.
