Where it was recorded

The discs' own checklists select Kinglet Calyptura at 1 locality.

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.

Serra dos Orgãos SRRB

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

Described by Descourtilz as "brief, sharp and disagreeable"(⁹⁴).

Behavior

In 1996 a pair of this species was sitting on top of medium sized trees.

Habitat and status

Rediscovered after more than 100 years on October 27, 1996, by Richardo Parrini about 5 km south of Teresopolis on the road to Rio de Janeiro. In the following days it was observed by several other ornithologists from Rio de Janeiro (⁹⁵). The location is at 800 meters and close to a road going off to the east on the highway close to the gas station called "Posto Garrafão" in the forested foothills of the Serra dos Orgãos. However it has not been seen there since. In the middle stratum of primary forest and thick secondary growth of abandoned clearings (⁹⁴). This species qualifies as 'critical', because of its tiny population (¹⁰³).

Distribution

The original specimen was collected in the vicinity of Rio de Janeiro. Also near Cantagalo and Nova Friburgo in Rio de Janeiro State (⁴⁰). 750-1500 meters (⁹⁴).

On March 4, 2006 an individual of Calyptura cristata was observed in a mixed tanager flock at Folha Seca NW of Ubatuba. The bird was observed by Dr. Martin Schaefer, University of Freiburg, Germany

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 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.
