E-mail: henry@mnhn.fr The Tropical Andes biodiversity hot-spot holds 19 % of restricted-range bird species (BirdLife International and Conservation International 2005). Humid montane forests are rich in endemic species. Nevertheless, anthropogenic deforestation is making this habitat, together with the localized bird species it contains, of special conservation concern. One such threatened species is the Chestnut-bellied Cotinga (Doliornis remseni). Within its restricted range it is rare, occurring at high altitude on the eastern cordillera of the Andes in Ecuador and in the Central Andes of Colombia (BirdLife International 2007; Figure 1). This species was only recently described (Robbins et al. 1994), and its biology is very poorly documented. It was listed as Vulnerable (IUCN 2006) because of its limited range (11,000 km²), its small, decreasing population (2,500 - 10,000 individuals) and the destruction of its habitat (Renjifo et al. 2002; BirdLife International 2007). On 23 February 2006 (16:10 h), in the Llanganates National Park (NP), province of Tungurahua, Ecuador (01°05'55" S, 78°18'27" W; 3,390 m; Figure 1), a male Chestnut-bellied Cotinga was observed, first in flight and afterwards perched, ca. 20 m down from the rock bar closing off Yanacocha Lake. The rufous belly, contrasting with blackish-gray head, wing, back, and tail, and jet black crown identified it (Robbins et al. 1994). It remained motionless for ca. 5 min, perched on a dead branch extending above the forest canopy (Figure 2). Perching motionless at the very top of the crown of trees appears to be a common behavior in the species (Renjifo M. 1994, Robbins et al. 1994, G. H. Rosenberg, in litt.). A second individual arrived, and both disappeared into the forest canopy. Although existence of a resident population remains to be documented, this new locality fills an important distributional gap in central Ecuador (Figure 1). The closest locations documented for the species are Cerro Mongus, south-east of Carchí, 180 km to the north (Robbins et al. 1994), and Gualaceo-Limón pass, province of Morona- Santiago, 215 km to the south (ca. 03°00' S, 78°39' W; ca. 3,500 m; G. H. Rosenberg, in litt.). Figure 1. Known localities of occurrence and altitudinal range (2,875 - 3,650 m; dark grey area) for the Chestnut-bellied Cotinga.
