The Cipo Cinclodes Cinclodes espinhacensis is a recently described furnariid endemic to the campos rupestres of Serra do Cipó, southern Espinhaço Range, southeastern Brazil. It is an "Endangered" species and its natural history is poorly known. We studied the Cipo Cinclodes breeding biology at Serra do Breu, where we found six nests on rock outcrops in 2009 and 2012. At least one nest was reused in different years. Breeding season was from September (nest building) to January (dependent juveniles). Nests were shallow cups or beds placed in chambers at the end of earthen and/or rocky tunnels or crevices on rock outcrops. Clutch size was 2-3 eggs. It exhibited biparental care during all nest stages. We demonstrated that the nesting habits of Cipo Cinclodes agree with those reported for other species of the genus, although some details differ from what is known for the closely related species, the Long-tailed Cinclodes Cinclodes pabsti.
