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
The voice is described as 'oo-OOT' (121). Since I never had the chance to hear or record this species, I have added the call of Claravis montedoura which forms a superspecies with Claravis godefrida with the assumption that the calls of these two taxa might be similar.
Behavior
Forages in dense bamboo forest. The preferred food is bamboo seeds; also eats fruits. Was found outside the breeding season in small groups.
Breeding
Teresopolis November / December. Nest in bushy tree.
Habitat and status
At the verge of extinction. Occurs in dense forests and forest borders with bamboo (Guadua, Chusquea). Dependent on large areas of bamboo forests which are now fragmented and reduced in size. The remaining tracts seem to be too fragmented for a food specialist such as this dove. Was apparently still common in the late 1800 around Rio de Janeiro.
Distribution
Originally throughout. Recently seen in Estado Rio de Janeiro at Itatiaia and Serra dos Orgãos; formerly Cantagalo, Nova Friburgo. In Estado São Paulo recently seen only at Ubatuba, Boraceia (122). Up to 1400 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.
