Black-banded Woodcreeper

How to find it

At Tapantí, birders have met this woodcreeper on the steep Arboles Caidos trail. A Costa Rica guide writes that you improve your odds by moving slowly and sitting and waiting, as with antpittas. A guide to Tapantí advises checking the mixed-species flocks along the main park road, driving slowly with the windows down and listening for flock birds. Timing matters: one guide walked Arboles Caidos on a sunny morning at the least birdy time of day, saw very little and missed it. Ant swarms are also worth watching, and mixed-species flocks at Reserva El Copal, near Tapantí, offer a chance at rarities that include this bird.

How to recognise it

Look for a large, heavy-billed woodcreeper with a strong, straight, blackish bill.

The upperparts are streaked and the belly is banded. Hold that pairing in mind: streaks above, bars below.

Across its range it measures about 24 to 30.5 cm, with a long tail and a straight bill of medium length.

The Costa Rican subspecies has more bars and spots and fewer streaks on the underparts than some other forms, so check the back as well as the belly before you decide.

Behaviour and diet

In Costa Rica it prefers the understory and can show up at army ant swarms. On a 2023 tour, one appeared above a swarm at Bosque de Paz and birders got long scope views.

Across its range it eats mostly arthropods such as insects, spiders, scorpions and centipedes, and it also takes small vertebrates such as lizards and sometimes frogs. Birds in mountain areas follow army ants much less than lowland birds do. They often forage alone and sometimes join mixed-species flocks.

Where it lives

In Costa Rica it appears to occur only in old growth forest at middle elevations. In Costa Rica and Panama it ranges from about 500 to 2,000 m (1,600 to 6,600 ft).

The Costa Rican form lives in the highlands of central and southeastern Costa Rica, in the subtropical to lower temperate zones, and one tour company called it rare at mid elevations on the Caribbean slope. It also reaches the Pacific slope of western Panama.

Across its wider range it mostly uses the interior of mature primary forest, and it also uses forest edges and mature secondary forest. It rarely uses plantations.

Similar birds

Northern Barred Woodcreeper is also large and black-billed, but it is unstreaked, and its banding can be subtle. It is fairly common in lowland and foothill forests and is often at ant swarms. Black-banded has streaks on the upperparts as well as belly bars, so look for streaking on the back.

Names and lore in Costa Rica

Costa Rican sources use the name Trepador Vientribarreteado. Other countries use different names, such as trepatroncos rayado in Colombia.

Status and conservation

The AOCR list marks it as R, and in Costa Rica it is a rarity at very low density, though its global conservation status is Least Concern.
