Black-capped Antthrush

How to find it

Learn the long, ringing song before you go, because antthrushes are heard much more often than seen. Focus on humid to wet primary forest and older secondary forest in the Caribbean foothills. Ravines and other spots with dense undergrowth are the places to scan and listen. Watch the forest floor for a lone bird or a pair. Keep an eye on any army ant swarm, since this species sometimes follows them. Expect to need patience, as it is uncommon here.

How to recognise it

Look for a chunky, short-tailed bird of the forest floor.

It is shaped a bit like a rail and walks like a chicken rather than hopping.

It is about 18 cm long.

Breast, neck and head are all grayish black.

There is bare blue skin around the eye.

That unbroken gray-black over the whole breast, neck and head is the mark to check when one steps into view. Be careful with guide plates: a reviewer noted that field guides, including a recent Costa Rica guide, pictured the Colombia and Ecuador form instead of the Costa Rica and Panama bird, so compare with photos of Costa Rican birds.

Behaviour and diet

This species is usually alone or in pairs in forest. It sometimes follows army ant swarms, so a swarm on the forest floor is worth a careful look. Antthrushes as a group are heard much more often than seen, which means patience and a quiet approach count for more than sharp eyes. In Costa Rica, breeding includes April and May.

Where it lives

In Costa Rica the Black-capped Antthrush lives on the Caribbean slope, in a narrow band of foothill elevation from about 400 to 1,200 m. One range note puts it on that slope from the northwest to the centre of the country. It is also found in Panama, where records reach somewhat higher, up to about 1,500 m. Look in humid to wet primary forest and older secondary forest, where it prefers ravines and other spots with dense undergrowth.

When to see it

Breeding in Costa Rica includes April and May.

Similar birds

Black-faced Antthrush is the common look-alike in Costa Rica, and its elevation range overlaps this species. Its black is limited to the face and throat, with rufous-brown upperparts, paler brown underparts and a white partial eye-ring. The Black-capped has black-gray over the whole breast, neck and head. At higher elevations through much of its range, Rufous-breasted Antthrush replaces it.

Names and lore in Costa Rica

Costa Ricans know it as Gallito Hormiguero Cabecinegro. Spanish sources also list the name Chululú de Cabeza Negra for the species.

Status and conservation

Resident (R) on the AOCR list, rated Least Concern by the IUCN, and described as uncommon in Costa Rica.
