About Cantorchilus semibadius (Salvin, 1870)
The riverside wren, scientifically known as Cantorchilus semibadius (Salvin, 1870), measures 13 to 14 cm (5.1 to 5.5 in) in length and weighs 17 g (0.60 oz). Adult riverside wrens have a bright orange-brown crown, with chestnut coloring covering the nape, back, and rump. Their tail is blackish with buff-white bars. They have a black-over-white supercilium, and the rest of their face is streaked and spotted in black and white. Their underparts, from the throat to the vent, are pale gray marked with narrow black bars; the gray becomes somewhat buffy toward the rear of the body. Juvenile riverside wrens are duller in color overall, with fine black scaling on the crown, and the black bars on their underparts are not as crisp. This species is distributed along the Pacific slope, ranging from Costa Rica's Gulf of Nicoya into western Panama. It inhabits dense vegetation, with a preference for areas along watercourses, the swampy edges of woodlands, or steep precipices. Its elevational range extends from sea level up to 1,200 m (3,900 ft).
