The account

Description

12 cm. A rather long tailed tyrant flycatcher of the interior of dense forests. Frequently lifts a wing up over the back.

Where it was recorded

The discs' own checklists select Sepia-capped Flycatcher at 27 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

A characteristic fast rolling sequence of low 'dre' notes such as 'dre dre dredre dredredredredredredredredre' rising slightly in pitch. This call is not repeated very often. Also a 'psewrr, rreo..' etc. (³⁰).

Behavior

Rather unobtrusive and quiet, a denizen of the lower forest strata. Forages by upward hover-gleaning and also consumes fruits (⁷⁴).

Breeding

Builds a hanging nest with a side entrance in a protected location (Ihering, ³⁰).

Habitat and status

Common in the lower strata (up to 3 meters) of humid and drier dense primary and secondary woodland.

Distribution

Throughout the area close to the shore and inland in suitable habitats. Up to 1200 meters in Itatiaia.

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.
