15 cm. Male: entirely black, with white on the underwing coverts that shows mainly in flight. Female: head and breast blackish with pale streaks; upperparts, wings and tail rufous; belly brownish. Bill heavy with a hooked tip.

Confusion species

The male Jet Antbird Cercomacra nigricans is also black, but slimmer, with a finer bill, white fringes on the wing coverts and white tail tips. Black-hooded Antshrike Thamnophilus bridgesi lives further west, on the Pacific slope of Costa Rica and western Panama, and has white spots on the wing.

Habitat

Dense thickets, vine tangles and second growth at forest edges and in clearings in the lowlands, often along rivers and in damp areas. It eats insects and other invertebrates.

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 eastern Panama. Outside the guide area in northern Colombia.

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

Listen first for the song at overgrown forest edges and along rivers in eastern Panama, then wait patiently for the bird to show briefly.

Conservation status

Not threatened. In the guide area local and restricted to eastern Panama.

Scientific name

Thamnophilus nigriceps | Sclater, 1869

Sclater described the species in 1869 and placed it straight away in the genus where it still stands. The genus Thamnophilus was introduced in 1816 by Vieillot. Thamnophilus is Greek, from thamnos 'bush' and philos 'loving': 'bush-lover'. nigriceps is Latin, from niger 'black' and -ceps '-headed', after the male's black head. The specimen the first description was based on came from Barranquilla, Colombia (originally given in error as Bogotá).
