The Chestnut‐capped Piha Lipaugus weberi sp. nov., is described from sub‐Andean forest on the northern slope of the Central Cordillera of the Colombia Andes. The new species appears most closely related to Lipaugus fuscocinereus of the Northern Andes including the Central Cordillera, but is much smaller, with a distinctive chestnut‐brown crown, yellow orbital ring, two modified primaries in the male, an overall darker grey coloration and unique vocalizations. It appears to be restricted to a narrow belt of premontane very humid forests (1500–1820 m asl) where it is fairly common. The restricted range and specific ecological requirements of Lipaugus weberi make the species of great conservation concern as the Central Cordillera has been severely deforested and remaining forests are highly fragmented. We present notes on the behaviour, ecology and conservation of this new species.
Se describe Lipaugus weberi sp. nov, de bosque subandino de la vertiente norte de la Cordillera Central de los Andes de Colombia. La nueva especie parece estar bastante relacionada con Lipaugus fuscocinereus de los Andes septentrionales incluyendo la Cordillera Central, pero es mucho más pequeña, presenta una distintiva gorra castaño opaco, anillo ocular amarillo, dos remeras primarias modificadas, la coloración gris más oscura y vocalizaciones ünicas. Esta especie se restringe a una franja angosta de bosque muy hümedo premontano (1500–1820 msnm), donde es relativamente comün. El rango restringido y los requerimientos ecológicos especificos de Lipaugus weberi hacen que esta especie sea de gran relevancia para la conservación, más aün debido al estado de deforestación severa de la Cordillera Central, en la cual los bosques remanentes son muy fragmentados. Presentamos anotaciones sobre la ecologia, el comportamiento y la conservación de esta nueva especie.
