Grey-chested Greenlet | Hylophilus semicinereus

Grijsnekvireo | Verdillo pechigrís | Verdinho-da-várzea

The Grey-chested Greenlet is a small greenlet of forest edges and várzea in Amazonia, with a grey breast and an olive-green back. In the guide area it occurs in north-eastern Peru and the extreme north-east of Bolivia. It often forages in the fairly low canopy of young or flooded forest.

Voice

A very high, fast series of even notes, wee-wee-wee-wee, of eight to twenty notes, often too fast to count. The song resembles that of Scrub Greenlet.

Confusion species

Ashy-headed Greenlet Hylophilus pectoralis has a grey head and a yellow breast band. Lemon-chested Greenlet Hylophilus thoracicus has a bright yellow breast and a pale eye. Brown-headed Greenlet Hylophilus brunneiceps has a brown head and lives mainly in forest on poor sandy soils. Dusky-capped Greenlet Pachysylvia hypoxantha has a brownish cap and yellow underparts.

Habitat

Canopy and edges of humid forest, várzea, permanently flooded forest and secondary forest, especially where the canopy is fairly low, up to about 400 m. It gleans insects from leaves in pairs and with mixed flocks. Little is known about the nest.

Where the bird is most at home, classified by the vegetation units of the Andes and the west coast.

Range and movements

Peru: in the north-east, in Loreto, mainly south of the Amazon. Bolivia: in the extreme north-east. Ecuador: not recorded with certainty; there are reports from the far east. Colombia: possibly in the east, unconfirmed. Absent from the Galápagos. Outside the guide area in southern Venezuela, the Guianas and Brazilian Amazonia.

Density map from the occurrence records of GBIF (2006-10-01 – 2026-09-30), counted per 1.41° 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

Search along rivers and in várzea around Iquitos, where the species forages with mixed flocks in low canopy. Listen for the fast, high series of notes.

Conservation status

Least Concern. The species has a large range and tolerates secondary forest.

Scientific name

Hylophilus semicinereus | Sclater & Salvin, 1867

Sclater & Salvin described the species in 1867 and placed it straight away in the genus where it still stands. The genus Hylophilus was introduced in 1822 by Temminck. The genus name comes from Greek hulē, 'woodland, forest', and philos, 'loving': 'forest-lover'. The species name comes from Latin semi-, 'half', and cinereus, 'ash-grey': 'half grey'. The specimen the first description was based on came from Belém, Pará, Brazil.
