The account

Description

5.9" Crown light rust-brown with a yellow superciliary from behind eye separating the crown from the blackish grey ear-coverts. Olive-brown on the back and wings. White throat otherwise grayish below with buff flanks. Long tail rusty-brown.

Immatures have a less distinct color pattern, the crown dull dark olive-brown and no black gular patch.

Where it was recorded

The discs' own checklists select Rufous-capped Spinetail at 26 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

Song 'dododo deet', with emphasis on last tone which has a higher pitch than the first three. Warning call 'tshrrr' (see cuts #4 and #5). Can also be heard on ¹¹³.

Behavior

Inquisitive, but often hard to see in its undergrowth habitat. Often in pairs.

Breeding

Nests were attached to lianas and consisted of a breeding chamber with a long tube-like side entrance (⁵¹).

Habitat and status

Common in undergrowth of humid primary and secondary forests, frequently at the forest edge. Less common inland in dryer forests.

Distribution

Throughout, up to 1400 meters. Does not go to such high altitudes as Synallaxis spixi (⁴⁴).

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.
