A streak-breasted wren that duets from Caribbean slope thickets

The Stripe-breasted Wren (Soterré Pechirrayado, Cantorchilus thoracicus) is a small wren of tangled edges on the Caribbean slope. Its streaked breast is unique among Costa Rican wrens, so it is easy to name once you get a look.

Getting that look is the challenge. It sings from dense cover, and pairs duet so tightly that it can sound like one bird. Its range covers only the Caribbean side of Central America, from eastern Honduras to western Panama.

On a trip we build, guests can meet it on forest trails around Arenal, where it is a listed specialty, and in the lowland forest at La Selva.

How to find it

Start at dawn and listen for duetting pairs calling from dense vegetation. Look for movement in thickets 1 to 3 m up, and check overgrown trail and road edges. It often answers playback of its song. Learn the song beforehand so you can tell it from a pygmy-owl. Be patient, because hearing is often easier than seeing in thick cover: one tour group heard it at La Selva and along the Río Tuis without seeing it. Pairs have also been seen near a jetty and along a road in the Tuis valley, in the Caribbean slope foothills.

How to recognise it

This is a small wren, about 11.5 to 12.5 cm long. Look for these marks:

Throat and chest with black, white and gray lengthwise streaks, ending sharply at a plain olive-brown lower belly.

A white eyebrow stripe running back from the bill above a dark eyeline.

White streaks over a blackish base on the face and sides of the neck.

A gray-brown crown, with dark brown back and shoulders.

Warm brown upperparts, brightest on the rump.

A dull black tail with buffy bars.

Behaviour and diet

It hops and climbs through tangles, picking prey from leaves and stems. Spiders, beetles, caterpillars, ants and grasshoppers are all on its menu. Pairs stay on year-round territories and do not migrate, and they defend them by singing duets from the territory edges. Small family groups of 3 to 5 may be seen during and after breeding. One birding tour found it in a small mixed flock on a trail at La Selva, alongside Bay Wren, Rufous-tailed Jacamar and Fasciated Antshrike.

Where it lives

In Costa Rica it lives mainly on the Caribbean slope, from sea level to middle elevations. That covers Limón province, eastern Alajuela and Heredia, and the Caribbean sides of the Central and Talamanca ranges. On the Pacific side it is found only locally, in the Térraba Valley and the Golfo Dulce region. It uses thick tangled growth at forest edges, in openings and along streams, and also lives in cacao plantations at lower elevations and shade coffee at higher ones. One Costa Rican site gives its range as sea level to 1,500 m, most often below 900 m, and says it avoids both deep forest interior and fully open ground.

When to see it

It nests between March and July in Costa Rica, and one site says activity peaks from May to July. It is described as vocal and easy to see all year, and early morning gives the best chance of hearing it.

Similar birds

Compare the Riverside Wren, which has fine, even barring below instead of streaks and is found on the southern Pacific slope. In foothill forest the songs of Stripe-breasted Wren and White-breasted Wood-Wren are confusing, and both can be tricky to see even though neither is rare.

Names and lore in Costa Rica

Costa Ricans call it Soterrey Pechirrayado. Elsewhere it has other names, such as Charralero Pechirrayado in Nicaragua and Sotorrey Pechirrayado in Panama. Costa Ricans call wrens in general "cucaracheros", which means roughly cockroach hunters.

Status and conservation

The AOCR list marks it R-END, a resident endemic, and the IUCN rates it Least Concern.

Photography tips

Early morning, from dawn to about 8 AM, is the best viewing time. Pairs sing duets from the edges of their territory, so scan overgrown edges and thickets 1 to 3 m up where the singing comes from.
