The account
Description
12 cm. A long-tailed green-and-yellow, rather chunky tyrannulet of the highlands. Bill short and thick, with a pink base to the mandible. Crown olive-green. Typically the cheeks are surrounded by an olive-green eyestripe and a stripe starting from the bill down below the cheeks and meeting the eyestripe behind the cheeks. Green above. Wings blackish-brown with two strong yellow-white wingbars. Below bright yellow. Tail blackish-brown frequently carried angled slightly upwards.
Clay et al. (75) point out that this species is most likely confused with Phylloscartes ventralis, however the stocky jizz, larger size and the slightly upward angled tail (see color sketch) are prominent features of this species. If seen close the yellow fringing of the tertials is different in the two species and this is a very good criterion. Virescens has broader fringing to the outer webs with less fringing on the feather tips. In ventralis the tips of the tertials have yellow dots and the fringing on the outer webs is rather narrow and dull (75).

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
A rapid series of snickering 'tick' sounds rising in pitch and then descending, about 1-5 sec. long. Also a deeper 'prrr' or 'piurrr'(track # 5). The distinct song often delivered as a dawn song is a fast 'di-dididididididididi', always descending in pitch in contrast to the song of Phylloscartes ventralis (check cut #1).
Behavior
Foraging mostly in low bushes up to 4 meters. Forages by hover-gleaning and does some sallying. Frequently in mixed bird parties.
Breeding
A nest found at Fazenda Intervales (Barra Grande, 800 meters, Nov. 9, 1995) was suspended over the side of a road embankment, attached to a fern-frond and had a side entrance, it contained 1 pull. The nest of Phyllomyias sclateri was described as an open cup (110).
Habitat and status
In open primary or secondary forest and forest edge with dense high undergrowth and high altitude scrub. Most common in more open areas with extensive low tree growth and bushes. I have never seen it "in the canopy of humid forest" (44).
Distribution
Probably throughout at higher altitudes (Serra Mantiqueira, Campos do Jordão, Fazenda Intervales, Nucleo Sta. Virginia), probably not below 800 meters and up to 2000 meters in the Serra Mantiqueira.

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.
