Streak-breasted Treehunter

Thripadectes rufobrunneus

In Spanish: Trepamusgo Cuellirojizo

  • Resident
  • Regional endemic

A big, skulking ovenbird of highland ravines, with a tawny throat and no eyestripe.

The Streak-breasted Treehunter (Trepamusgo Cuellirojizo) is a large, dark ovenbird of mountain forest, about 20 to 22 cm long and shaped a little like a thrush. It is endemic to the highlands of Costa Rica and western Panama, so seeing one means being in the right cloud forest.

In Costa Rica it is most common between about 1,200 and 2,500 m. On highland trips we build around the Savegre Valley and San Gerardo de Dota it is a listed target, and Tapantí is also a regular stop.

It is often hard to see, yet one tour group had incredibly close views in Savegre's oak forest. That is why it rewards patience.

How to find it

Look for it at cloud forest sites above about 1,200 m. Because it nests in burrows, it is often seen near embankments and forested streams. It is most likely to be spotted foraging on a mossy branch or in a dense tangle of debris. In Savegre's oak forest, tour leaders saw a large brown bird rummaging beside a trail, and it hopped closer and came out into the open at eye level. Listen for the loud 'chack' or 'zeck' and the scolding song, and scan trail edges slowly.

How to recognise it

This is a large, dark, thrush-shaped ovenbird, about 20 to 22 cm long.

The crown is blackish with olive streaks. The tail is chestnut-brown. The bill is black. The brown breast carries narrow buff streaks.

The throat is the feature to look for. It is described as dull buff in general accounts, but in Costa Rica it is tawny to orange, which is why the Spanish and German names mention it. One birder described a large chestnut bird landing at eye level on a bank, with a rich buffy throat.

There is no pale stripe behind the eye. Together with its size, that plain face helps when you are sorting a bulky brown bird in dim forest.

Behaviour and diet

It eats mainly insects and spiders, and also small vertebrates such as frogs and salamanders. Photos from the Turrialba Volcano slope show birds carrying a lizard, a caterpillar and a beetle larva.

It usually forages alone or in pairs and seldom joins mixed-species flocks. A Costa Rica blogger says it might get curious about scolding bush-tanagers, but is not expected to join flocks, though one bird at Bosque de Paz did appear at the edge of a flock following army ants.

It nests in a tunnel dug into an earth bank, up to about 70 cm long. The clutch is two eggs. It is a year-round resident and does not migrate.

Where it lives

It lives in mountain forest and mature secondary forest, and particularly favors ravines with streams and many epiphytes. It tolerates some forest fragmentation.

It ranges from 700 to 3,000 m but is most common in Costa Rica between about 1,200 and 2,500 m. It is found in the Talamancan montane forests through most of the country and into western Panama. Records include Tapantí National Park in Cartago, Reserva Forestal Los Santos in Pérez Zeledón, Cloudbridge Nature Reserve and the Turrialba Volcano slope.

Similar birds

It is much larger than the foliage-gleaners of the Turrialba area, and the lack of a stripe behind the eye rules out several of them. Lineated Foliage-gleaner has been listed at San Gerardo and Tapantí, so compare size and face carefully.

Names and lore in Costa Rica

Besides the official name Trepamusgo Cuellirojizo, Spanish sources also list Trepamusgo Pechirrayado and Trepapalo de Cuello Rojizo. The type specimen was collected near San José, and the genus name means roughly 'wood-moth pecker' in Greek.

Status and conservation

The AOCR lists it as a resident endemic (R-END), and the IUCN rates it Least Concern, with 20,000 to 50,000 mature birds thought to be stable.

Photography tips

Expect a skulker. One Costa Rica blogger calls it a part-time skulker, and others say it skulks along roadsides. Low light on an afternoon hike made detail hard to see for one group, while another found a bird on the road the next morning. Patience on embankments, trail edges and streamside tangles gives the best chance of a clear view.
