Cocoa Woodcreeper

How to find it

Learn the sharp, piercing call first, since the bird is often detected by voice. Walk forest trails in the humid lowlands, such as those at Carara and La Selva. Check army ant swarms, a good place to look for it. A canopy tower can also give views in a mixed group. A March 2024 tour called it one of its more commonly heard and seen woodcreepers, with great looks at La Selva and Carara. Do not be discouraged by a heard-only bird: at La Selva one tour heard it calling and never saw it, and the guide noted that this is normal for such a common species.

How to recognise it

Look for a long-billed, long-tailed woodcreeper with buffy streaking on the head, neck and breast. The bill is long, fairly heavy, pale and slightly curved downward.

Range wide, the upperparts, wings and tail are rufous, the underparts are olive-brown, and the breast has broad cinnamon streaks.

Adults measure about 21 to 25.5 cm and weigh about 43 to 58 g, so this is a big woodcreeper.

A Costa Rica guide gives a first rule for telling woodcreepers apart: focus on the head and bill.

Behaviour and diet

Range wide, it climbs trunks, often in a spiral, and works along branches, often on the underside. With flocks it forages at mid-levels, while at army ant swarms it forages much closer to the ground.

It eats mostly arthropods, and sometimes small frogs and lizards.

In Costa Rica, a tour report says this big lowland woodcreeper typically attends army ant swarms. At Carara one was heard calling from the forest during a swarm visit. A Pacific lowlands tour also recorded it from a canopy tower, in a mixed group with parrots and woodpeckers, so it can be seen from a tower as well as on trails.

Where it lives

In Costa Rica it is fairly common in forested parts of the humid lowlands. Tour reports call it fairly common in the wet lowlands and foothills of both the Caribbean and Pacific slopes.

It prefers forest over open ground more than the Streak-headed Woodcreeper does, but it also turns up at forest edges.

Range wide, it mostly lives in humid evergreen forest and also uses mature secondary woodland. Its range runs from southeastern Honduras through Nicaragua and Costa Rica into western Panama.

Similar birds

Streak-headed Woodcreeper is more of an open-country and edge bird. Long-tailed Woodcreeper has more obvious pale spectacles and less streaking on the head than Cocoa and Streak-headed. Spotted Woodcreeper is a common bird of mixed flocks in foothill and cloud forest. Ivory-billed Woodcreeper has a strong, straight, pale bill and a paler head, and in Costa Rica is restricted to dry forest and riverside areas of the northwest Pacific. Some Central American field guides still use the name Buff-throated Woodcreeper, a species found only in South America.

Names and lore in Costa Rica

In Costa Rica the official Spanish name is Trepador Gorgianteado. Elsewhere it is called trepatroncos cacao in Colombia, trepatroncos chocolate in Panama and trepador chillón in Venezuela. The Latin species name susurrans means murmuring or whispering, and the genus name means sword-billed in Greek.

Status and conservation

It is a resident on the AOCR list (R), and BirdLife International lists the species as Least Concern.

Photography tips

A heard-only bird is common, so patience matters. Army ant swarms bring it closer to the ground, and a canopy tower can offer a view in a mixed group. A morning trail walk at Carara has given great views.
