The account, continued
Voice
Call 'tchoc' (119). The songs included here are from Bolivia and are quite different from each other. The first song containing some gurgling notes and whistles recalls the song of Dolichonyx oryzivorus. I have no information about the song of the nominate race from Southeast Brazil.
Behavior
Forages in trees and shrubs.
Habitat and status
Extinct in Southeast Brazil due to the activity of bird trappers. Was found in scrubby pastures with trees, forest border, shorelines of lakes and rivers, bushy marshland.
Distribution
Was apparently found throughout Estado Rio de Janeiro and Estado São Paulo. Historical records are extralimital, e.g Franca. To 1100 meters (40).
Decoded from the disc's own bytes. Each part is shown under the heading the disc files it under, and the wording, spelling and punctuation are the author's.

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.

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.
The account in the Disc 1 · 2011 revision
The 2011 Disc 1 revision carries this account text unchanged from the Disc 3 release.
