Black-throated Wren

How to find it

Listen first, because the song is the way to locate this wren. Around Arenal and similar foothill spots it is heard singing from older, dark tangles. Try forest edges, old clearings and stream sides where the vegetation is tall and dense. Keep your eyes low, since it forages close to the ground. Expect partial or brief views, as it is very secretive and often tries to hide behind a branch.

How to recognise it

This is a small wren, about 15 cm long. Look for these marks:

Black face, throat and upper chest.

A thin pale eyebrow.

White streaks on the ear area.

A plain chestnut brown back.

A reddish-brown band across the middle of the chest, turning reddish chestnut on the lower chest and belly.

Young birds are a duller, more even dark brown, so they lack the crisp black front of an adult. Against that plain back, the black face and chest are the marks to watch for if the bird shows itself in a gap in the tangle.

Behaviour and diet

It forages close to the ground in dense vegetation, and its diet is mostly insects and spiders. Birds generally live in pairs, which fits the duets you may hear from a tangle.

It behaves a bit like an antbird, skulking in cover, but when it sings it is clearly a wren. Breeding in Costa Rica probably runs from April or May to August.

Where it lives

In Costa Rica it lives in dense second growth at forest edges, openings, abandoned clearings and along streams. It generally prefers taller vegetation than the Plain Wren.

It is a locally common resident of lowlands and foothills, going up to about 1100 m on the Caribbean slope. It ranges across that slope and also reaches the Pacific side around the bases of the Guanacaste volcanoes.

When to see it

Breeding in Costa Rica probably runs from April or May to August.

Similar birds

The Plain Wren (guachipelín) is the plainest Costa Rican wren, prefers lower, more open second growth and sings from coffee farms, while the Black-throated Wren likes taller vegetation and has a black face and chest. At Arenal-type foothill sites, the confusing songs of White-breasted Wood Wren and Stripe-breasted Wren come from the forest, while the Black-throated sings from older tangles and Bay Wren chatters at the edge.

Names and lore in Costa Rica

The Costa Rican Spanish name is soterrey gorginegro (soterré on the AOCR list). Other Spanish names are cucarachero gorginegro and ratona de garganta negra. Costa Rican wrens are often called cucaracheros, which means cockroachers.

Status and conservation

The AOCR list marks it R-END, a resident regional endemic, and the IUCN lists it as Least Concern, locally common in its natural habitats.

Photography tips

This wren is very secretive and forages low in dense tangles, so it is usually noticed first by its rich whistled song. Expect partial views, and be patient with the spot where the song is coming from.
