Justification:

Andigena nigrirostris occurs in Colombia on both slopes of the West (south to Cauca), Central (head of the Magdalena valley in Huila and east slope in Putumayo and Nariño) and East (south to Cundinamarca and west Caquetá) Andes; in north-east Ecuador (Napo) on the east slope of the Andes; and in north-west Venezuela (Trujillo and Táchira) (Fjeldså and Krabbe 1990, Hilty and Brown 1986). This species has a large range, with an estimated global extent of occurrence of 110,000 km². It is relatively common in montane evergreen forest and forest edge at 1,600–3,200 m, and to 1,200 m on the Pacific slope and east slope of the East Andes (Hilty and Brown 1986, Stotz et al. 1996). However, it is increasingly local owing to habitat destruction (Stotz et al. 1996). Unplanned colonisation following the completion of roads and massive logging concessions have cleared or degraded many of its Chocó forests, and deforestation is accelerating (Fjeldså and Krabbe 1990, Stattersfield et al. 1998); a long history of human colonisation on inter-Andean slopes has left only remnant forest patches, pasture and plantations (Wege and Long 1995); and extensive degradation in the East Andes has largely cleared west slopes for intensive crop cultivation and pasture (Stattersfield et al. 1998). The global population size has not been quantified, but it is believed to be large as the species is described as 'frequent' in at least parts of its range (Stotz et al. 1996). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
