Description

17 cm. Smaller than Tityra cayana. Bill black, the mandible bluish-gray.

Male has a black crown and cheeks and is whitish-gray above. Wings black with the exception of the tertials which are white. Whiter below. Tail black.

Female is like the male, but the front of the head is buffy, the cheeks are rufous and the back is a darker gray streaked dusky.

Where it was recorded

The discs' own checklists select Black-crowned Tityra at 15 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 recorded locality lies beyond the map's edge and is listed below instead.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

The calls are described as being drier than those of other Tityras, like 'zick-zick-zick-' (⁴⁴). However the recording included here, a hard, rolling 'drrrrrr', is very similar to the vocalizations of Tityra cayana.

Behavior

Remains in the upper level of large forest trees well above ground.

Habitat and status

Regularly encountered but rarer than Tityra cayana in the canopy of humid primary and mature secondary forest and forest borders.

Distribution

Recorded from the Serra do Mar, Serra Mantiqueira, Serra dos Orgãos (¹⁵), and near Rio de Janeiro (³⁰). from São Paulo state reported from Ubatuba and also from the north of the State, Rincão, Ituverava, Silvania etc. (⁴⁰). Up to 900 meters.

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.

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.
