Rufous-backed Wren

How to find it

Listen first: its loud, harsh, repeated chattering usually gives away its spot in low brush. Look in low scrub, acacia trees, cactus, gardens and bushes near paths, as around Las Catalinas on the Guanacaste coast. It is most vocal in early morning and late afternoon, and it is up and foraging in gardens by about 5 a.m. Watch for it perched in the open on branches, fences and roofs, and check acacias and thorny shrubs for the round nests. Beach hotel grounds can be an easy place to meet it.

How to recognise it

This is a large wren with a bold pattern.

Crown and eyestripe: black, split by a thick white line above the eye.

Eye: red, with a black stripe running through it.

Nape: rufous.

Upperparts: streaked cinnamon to chestnut, with a spotted upper back.

Wings and tail: barred in pale and dark brown, with much white in the tail and bold white tail bars.

Underparts: white.

Bill: fairly long and curved.

Adults are about 17 cm long. Young birds look duller above and buff below, not white.

Behaviour and diet

It forages actively for spiders and insects in low vegetation, on epiphytes and along branches. Birds often breed cooperatively, and family groups interact and display their tail and wing feathers.

Nests are round with a side entrance, placed 1.5 to 8 m up in thorny trees or shrubs. Families may roost together in dormitory nests after breeding. Birds hold territories all year. In Guanacaste a lodge page says the wren often cocks its head at passing guests and stands its ground against larger birds with loud, rapid calls.

Where it lives

In Costa Rica the Rufous-backed Wren lives in dry forest, open woodland, scrub, second growth and savanna, and it is at home in gardens too. It is found mainly on the Pacific side of the central mountain ranges, from sea level to about 800 m, though another account gives an upper limit of 1150 m.

It occurs in northwestern Costa Rica, including Guanacaste and the Nicoya Peninsula, and it now reaches the Central Valley. Above its usual elevation it is rare.

When to see it

It is listed among species that are resident or commonly possible all year in coastal Guanacaste.

Similar birds

It was once lumped with the Veracruz and Russet-naped wrens as Rufous-naped Wren, and of these only this species reaches Costa Rica. Its field marks are bold white tail bars and a spotted upper back. Being the largest of the country's 22 wrens also helps separate it from the smaller species.

Names and lore in Costa Rica

Costa Ricans call it Chico Piojo or Salta Piñuela, and Soterrey Nuquirrufo is also used. One household helper calls these wrens "chicos". A local article calls the bird a natural alarm clock because it is up and foraging in gardens by about 5 a.m. Nicaragua uses saltapiñuela nuquirrufa, and Guatemala uses names such as zacualpilla and porosoco.

Status and conservation

The AOCR list marks it as a resident (R), and IUCN rates it Least Concern, with a population suspected to be stable.

Photography tips

Family groups come close to houses and sheds, which makes them easier to watch. Look for them perched in the open on fences, roofs and branches, and for displays of tail and wing feathers when groups interact. Early morning and late afternoon, when they are most vocal, are good times to try.
