Primer registro de simpatría en dos especies de Scytalopus (Fam. Rhinocryptidae) en Zapallar, Región de Valparaíso, Chile

The Magellanic Tapaculo Scytalopus magellanicus is found in Chile from Cape Horn in the south to the Atacama Mountain Range and Termas del Toro in the north. The other species of the genus observed in Chile is the Dusky Tapaculo Scytalopus fuscus, which is distributed from Atacama in the north to the Imperial River and the Cordillera de Nahuelbuta in the extreme south. Some publications state that these two species are found in sympatry between the Imperial River and the Nahuelbuta Mountain Range (38° S), and Concepción and Bulnes (37° S). In this study we recorded observations and songs of individuals of both tapaculos species in the same fragments of the relict forests of Zapallar (Valparaíso Region, Chile). These are the first records that indicate that the geographical range of sympatry between these two Scytalopus species extends 5° north of 32° S along the Pacific coast.
