Confusion species

Lesser Greenlet Pachysylvia decurtata is more compact and shorter-tailed, with a white eye-ring and no yellow forehead. Scrub Greenlet Hylophilus flavipes has a pale eye and lives mainly low in scrub.

Habitat

Forest edges, secondary forest, gallery forest and dry to semi-humid woodland, also trees in pastures, in the lowlands. Forages in the canopy for insects, often in mixed flocks.

Where the bird is most at home, classified by the vegetation units of Mexico and Central America.

Range and movements

In the guide area only in Panama, mainly in the centre and east. Outside the guide area in northern Colombia, Venezuela and on Trinidad.

Density map from the occurrence records of GBIF (2006-10-01 – 2026-09-30), counted per 0.7° grid cell and per month and divided by all bird records in that same cell — so the number of birdwatchers does not shape the picture. Colour depth follows that share and fades out gradually, so the map does not follow national borders. Country outlines: Natural Earth (public domain).

How and when to look

Most likely at forest edges and in drier woodland in central and eastern Panama; look for the yellow forehead and dark eye.

Conservation status

Not threatened. Fairly common within its range.

Scientific name

Pachysylvia aurantiifrons | (Lawrence, 1861) (GBIF: Hylophilus aurantiifrons)

Lawrence described the species in 1861 as Hylophilus aurantiifrons; because it was later moved to another genus, the author and year stand in brackets. The genus Pachysylvia was introduced in 1850 by Bonaparte. Pachysylvia combines Greek pakhus 'thick, stout' with the genus Sylvia (warblers), after the stocky build. aurantiifrons is Latin, from aurantius 'orange' and frons 'forehead', after the golden forehead. The specimen the first description was based on came from along the Panama Railroad, Panama.
