Range Description

Rallus semiplumbeus occurs on the Ubaté-Bogotá plateau in Cundinamarca and Boyacá in the east Andes of Colombia. The race peruvianus of Peru is only known from its type material, collected in 1886, and is probably extinct (del Hoyo et al. 1996). In Boyacá, it is known from Laguna de Tota and, in Cundinamarca, it has been recorded at a minimum of 21 localities. The Ubaté-Bogotá plateau formerly held enormous marshes and swamps, but few lakes with suitable habitat remain (Fjeldså and Krabbe 1990). Although declining, it is still uncommon to fairly common, with notable populations including c.400 birds at Laguna de Tota, c.50 territories at Laguna de la Herrera, c.110 birds at Parque la Florida (Lozano 1993), and those at La Conejera Marsh and Laguna de Fúquene (F. G. Stiles in litt. 1999).
