The account
Description
20 cm. A chunky furnarid of epiphyte-laden Atlantic forest. Bill long. Above with blackish crown and rusty-brown back with sharp buff streaks, the only Brazilian furnarid with this characteristic with exception of Heliobletus contaminatus which is much smaller. Prominent yellow superciliary. Lores and auricular streak dark brown. Throat uniformly buffy-yellow. Chest and belly with strong dark brown and buff streaks. Wings dark brown with buffy axillaries and underwing coverts. Tail reddish-brown, graduated, not too long.
The juvenile has a less sharp streaking pattern.

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.
The account, continued
Voice
A loud well spaced raspy 'wriip wriip wriip wriip', often interspersed with a loud chattering. "song" a fast staccato' tektektektektektektek' followed by a sequence of raspy 'wrip wrrip wriip wrrip'
Behavior
In forest at all levels, frequently alone, foraging in bromeliads and moss laden limbs.
Habitat and status
Uncommon to reasonably common in humid rainforest.
Distribution
Throughout the area, encountered with regularity in the Serra do Mar, Serra Mantiqueira and Serra Paranapiacaba. From sea level to about 1000 meters.

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.

Review notes
review_0010
Recovered review record — open: audio classification; exact_unique
Evidence: unlabeled entry occurs in the first terminal segment and has recording-style location/date metadata; filename exists as both audio and image · Recommended: Open the referenced media in a safe player/viewer and confirm species/type; do not alter the source file.
Review v1.1 decision — resolved_by_context
Reviewer: ChatGPT structural audit
Notes: Reference 1833 is in the first terminal (recording) segment and includes location, date, weather, habitat, and associated-species metadata. The audio file 1833.mp3 is therefore the intended asset; 1833.jpg is independently associated with another account.
