Range DescriptionDysithamnus occidentalis has been recorded from four regions of the Andes in south-west Colombia, from one region in north Ecuador, and from at least four regions in east Ecuador (Collar et al. 1992, Whitney 1992, Krabbe and Palacio 1999, Ágreda et al. 2005, Harris et al. 2008). The nominate subspecies occurs on Pacific slope of the west Andes (Valle del Cauca, Cauca and Nariño), Colombia, particularly in Munchique National Park and surrounding areas, and there is a single record presumably of this subspecies from the west slope in Carchi, Ecuador (Krabbe and Palacio 1999, Ridgely and Greenfield 2001). In Ecuador the subspecies punctitectus occurs in the eastern cordillera of the Andes, mainly on the east slope (Napo and Morona-Santiago) and has recently been found as far south-east as the Cordillera del Cóndor, Morona-Santiago (Ágreda et al. 2005). The species may occur as far south as the south-eastern slope of the Cordillera del Cóndor, Cajamarca, north Peru (Schulenberg et al. 2007, Harris et al. 2008). It is generally rare, although it has been found at reasonable densities on Volcán Sumaco, Ecuador. It is likely to be declining in numbers.
