Where it was recorded

The discs' own checklists select Itatiaia Thistletail 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

Song: A fast high 'zizizizirrrr... zizizizizizirrrr... zizizizizizizirrrrr' and variations thereof. Call: 'ziieee... zieee....'

Behavior

Moves around inconspicuously close to the ground in dense scrub and grass. When singing, it is frequently exposed on top of a bush. Usually in pairs.

Breeding

Nest described by Sick (³⁰) as being in bushes, round with a high side entrance.

Habitat and status

An endemic spinetail occurring above the tree limit in the highest mountains of Southeast Brazil. Common in low scrubby areas interspersed with grassy patches and rocks.

Distribution

Est. Rio de Janeiro (Serra dos Orgãos, Serra Mantiqueira, Desengano State Park) and adjacent peaks in Est. São Paulo at elevations from 1900-2800 meters. (See ⁵².)

Taxonomy notes

Put in the genus Schizoeaca by Vaurie (⁴¹).

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.

How that was established

Disc 2 · 2001: 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.

Recovered evidence that has not been settled. It is published because leaving it out would misrepresent what the discs contain.
