The streak-breasted treehunter (Thripadectes rufobrunneus) is a passerine bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Costa Rica and Panama. The streak-breasted treehunter was formally described in 1865 by the American amateur ornithologist George Newbold Lawrence from a specimen collected by Alexander von Frantzius near San José in Costa Rica. Lawrence coined the binomial name Philydor rufobrunneus. The specific epithet rufobrunneus is Modern Latin meaning "brown". The streak-breasted treehunter is now placed in the genus Thripadectes that was introduced in 1862 by Philip Sclater.
The streak-breasted treehunter is monotypic: no subspecies are recognised. It and the black-billed treehunter (T. melanorhynchus) form a superspecies. The streak-breasted treehunter is 20 to 22 cm (7.9 to 8.7 in) long and weighs 48 to 54 g (1.7 to 1.9 oz). It is a large, dark furnariid with a thrush-like shape. The sexes have the same plumage. Adults have a mostly dark brown face with dull rufescence on their ear coverts and a dark ochraceous malar area with dark flecks. Their crown is blackish with long olive streaks... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Streak-breasted Treehunter is recorded against all the birds logged in Arenal Volcano National Park (87 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
