The account

Description

13 cm. Male has a black cap with a blue hue and a gray supra-loral area. Back gray with thick black stripes. Rump gray. Wings black with white scapulars, two white wing bars and white margins to the flight feathers. Below gray. Tail black with white tips on the outer rectrices.

The female is like the male, but has a rufous crown (which differentiates it from the female Pachyramphus polychopterus) and a white supra-loral spot. Shoulders are olive-green. Below yellowish-white.

Each plate is labelled with the disc's own caption.

Where it was recorded

The discs' own checklists select Black-capped Becard at 8 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

The most common call is a fast 'do-wi-do-wit......do-wi-do-witt......' and variations thereof. It also has calls similar to those of Pachyramphus polychopterus (cuts #2 and #4) and they are sometimes not differentiable.

Behavior

Foraging in the canopy of large forest trees. Sometimes in mixed bird parties.

Habitat and status

A becard of the humid forest canopy. Rather common in the interior of humid primary and mature secondary forest. Seems to require large tracts of intact and undisturbed forest.

Distribution

Throughout. We recorded it from sea level in the Serra do Mar (Ubatuba and the Corisco Trail near Picinguaba), PE Jacupiranga, and from Jureia near Peruibe. Pinto reports it from Sepetiba west of Rio de Janeiro and from São Sebastião, São Paulo state. To 500 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.

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.
