The streak-breasted treehunter (Thripadectes rufobrunneus), is a passerine bird which is endemic to the highlands of Costa Rica and western Panama. This large treehunter is found in hills and mountains from 700 m up to 2500 m altitude, rarely to 3000 m, in damp epiphyte-laden forests and adjacent old second growth, especially in shady ravines. It builds a wide saucer nest of rootlets in a 60 cm long burrow in a steep bank, and lays two white eggs between February and August. Streak-breasted treehunter is easily distinguished from its relatives by its large size, heavy bill and breast streaking.
