Where it was recorded

The discs' own checklists select Black-eared Parrotlet at 7 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 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

Call a trisyllablic 'tiriri' (vocalization # 1) in contrast to the very similar bi-syllablic 'tiri' of Pionopsitta pileata (¹¹⁹), but not always clearly to separate when flying over.

Behavior

Forages in the canopy of trees and in tall shrubs in pairs or in small flocks.

Breeding

September-October.

Habitat and status

Humid lowland or lower montane rainforest mostly between 500-1000 meters (¹²⁷). Also found in sandplain forest close to the shore (¹²⁰).

Distribution

Rare and irregular. In Estado Rio de Janeiro seen in Tijuca National Park (1966, 1979, 1980), Pedra Branca State Park (1987), Cantagalo (1854-56), Teresopolis (1991), Desengano State Park (1987), Itatiaia (1989), Viscode de Maua and Maringa (1991). In Estado São Paulo, Bananal (1989), Ubatuba (1999, Willis, E. O., H. Remold, F. Mueller, unpubl.), Ubatuba (1980), Ilha do Cardoso near São Luis do Paraitinga (¹¹⁹) (¹²²). To 1700 meters

Taxonomy notes

An endangered species probably due to widespread habitat loss and forest degradation (¹²²).

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.
