The russet-crowned crake (Rufirallus viridis) is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Bolivia, Brazil, Colombia, Ecuador, the Guianas, Paraguay, Peru, and Venezuela. The russet-crowned crake is 16 to 18 cm (6.3 to 7.1 in) long. Males weigh 55 to 63 g (1.9 to 2.2 oz) and females 69 to 73 g (2.4 to 2.6 oz). The sexes are alike. Adults have a black bill, red legs, gray face, and russet crown. The nominate subspecies has brownish olive upperparts and rufous underparts. Juveniles are light brown with a black face and dull pink legs. Adults of R. v. brunnescens are slightly larger than the nominate and have browner upperparts and a paler head and underparts. It is most vocal in early morning and evening. Its call has been described as a "dry rattling like the sound of a seashell wind chime". The nominate subspecies of russet-crowned crake is widely distributed from far eastern Colombia and southern Venezuela east through the Guianas into Brazil and south and west into eastern Peru, northern and eastern Bolivia, and eastern Paraguay. A separate population is found in Ecuador's Zamora-Chinchipe Province and another in southeastern Brazil between the states of Alagoas and São Paulo. R. v. brunnescens is found in north-central Colombia from the lower Cauca River valley east into the middle Magdalena River valley. The russet-crowned crake mostly inhabits terrestrial landscapes; in contrast to many other species in its family it is usually not found in marshes. It is found in second-growth sapling thickets, grassy or brushy pastures, overgrown wastelands and roadsides, and gardens at the edges of small communities. In elevation it ranges from sea level to 1,200 m (3,900 ft). The russet-crowned crake's movements, if any, have not been documented.
