The account

Description

11 cm. A stocky tyrannulet with a thick and stubby unicolored black bill. Olive gray-brown above, the head being grayer than the back and with a white superciliary stripe. Wings grayish-brown with two dull yellow-green wing-bars. Throat white. Below yellowish with olive-gray clouding and washed-out streaking. Tail black, relatively short, but longer than in Phyllomyias burmeisteri.

Where it was recorded

The discs' own checklists select Planalto Tyrannulet 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.

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 ascending whistles of the Planalto Tyrannulet are far carrying and are a characteristic sound heard almost everywhere with exception of the coastal lowlands. Commonest call is a diagnostic loud three-syllable whistle 'pui pui puiiit' and variations thereof are used in duets which are intermixed with single 'prrrit' notes and sometimes with series of 'prii-prii-prii-prrrrr-prrrrr' calls.

Behavior

Foraging singly or in pairs high in the canopy. The main foraging modes of this species are frugivory, perch-gleaning and upward hover-gleaning from an enclosed position within the vegetation. The hawking flights are horizontal or upward. Hovering may start long before the capturing flight begins (⁷³,⁷⁴). Feeds mostly on small berries, e. g. Loranthaceae (Mistletoes). Frequently in mixed bird parties.

Breeding

Nests of Phyllomyias have been described as open cups (⁸⁶).

Habitat and status

Fairly common in canopy of primary and secondary upland forest. Often in groups of tall trees and gallery woods far away from large forested areas.

Distribution

Nearly throughout, up to 2000 meters in the Serra Mantiqueira but not found in the Atlantic lowlands or on the lower slopes of the escarpments.

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.
