About Thripadectes rufobrunneus (Lawrence, 1865)
Thripadectes rufobrunneus, commonly called the streak-breasted treehunter, measures 20 to 22 cm (7.9 to 8.7 in) in length and weighs 48 to 54 g (1.7 to 1.9 oz). It is a large, dark furnariid with a thrush-like body shape. The sexes of this species have identical plumage. Adult streak-breasted treehunters have a mostly dark brown face, with dull rufous coloring on the ear coverts and a dark ochraceous malar area marked with dark flecks. Their crown is blackish, marked with long olive streaks. They have an indistinct olive collar that turns rufous along the sides of the neck. The back and rump are rich dark brown, which shifts to dark reddish brown on the uppertail coverts. The wings are rich dark brown, with slightly darker primary coverts. The tail is a rich chestnut-brown. The throat is dull ochraceous with a darker lower border; the breast and belly are brown, marked with narrow ochraceous streaks that fade away completely into the lower belly. The flanks are rich dark brown, and the undertail coverts are dark reddish brown with faint chestnut streaks. Adults have a dark brown iris, a black bill that sometimes has a grayish base to the mandible, and legs and feet that range from dark brownish gray to greenish gray. Juveniles have paler, less distinct streaking on the upper breast compared to adults. The streak-breasted treehunter is distributed across the Talamancan montane forests of most of Costa Rica, extending into Panama as far south as Veraguas Province. It also inhabits mature secondary forest, and particularly favors ravines with streams and large quantities of epiphytes. Its elevation range spans 700 to 3,000 m (2,300 to 9,800 ft), though it is most common between 1,200 and 2,500 m (3,900 and 8,200 ft) within Costa Rica.
