|Range Description:||Phylloscartes lanyoni occurs locally on the east and north slopes of the central Andes in Caldas and Antioquia, and on the west slope of the east Andes in Cundinamarca, Boyacá and Santander, Colombia. It is known from the type-series, taken in the lower Cauca Valley at the northern tip of the Andes in 1948, and a few modern localities in the middle and upper Magdalena Valley. It has been seen on several occasions at Río Claro Natural Reserve, and recently also at Anará (Renjifo et al. 2002), Antioquia, as well as near La Victoria, Caldas. It is respectively uncommon and common at El Vergel, Cundinamarca, and Monte del Diablo, Boyacá (Wege and Long 1995, Stiles et al. 1999, P. G. W. Salaman in litt. 1999) and is also present in Yacopi and La Palma municipalities, Cundinamarca (O. Cortes in litt. 2007). |
