starts withThe riverside wren is 13 to 14 cm (5.1 to 5.5 in) long and weighs 17 g (0.60 oz). The adults have a bright orange-brown crown; chestnut nape, back, and rump; and a blackish tail with buff-white bars. They have a black-over-white supercilium and the rest of the face is streaked and spotted black and white. From throat to vent their underparts are pale gray with narrow black bars; the gray becomes somewhat buffy to the rear. Juveniles are duller overall, have fine black scaling on the crown, and the underparts' black bars are not as crisp.
The riverside wren is found along the Pacific slope from Costa Rica's Gulf of Nicoya into western Panama. It inhabits dense vegetation, preferably along watercourses, swampy edges of woodlands, or on steep precipices. In elevation it ranges from sea level to 1,200 m (3,900 ft).
The riverside wren forages near the ground, usually in pairs or family groups. It sometimes briefly joins other species at army ant swarms. Its diet includes insects and other invertebrates.
The riverside wren appears to nest at almost any time of the year. Its nest is globular made of fine fibers; it drapes over a branch to form two chambers with an entrance hole in the outer one. It is often placed over flowing water, 1.5 to 2.2 m (4.9 to 7.2 ft) above it or the ground. The species also constructs "dormitory" nests for roosting. The clutch size is two.
