Conservation Status

The conservation status of the Multicolored Tanager is listed by both the IUCN and the Colombia Red List as Vulnerable (Angarita and Renjifo 2002, Fierro-Calderón and Johnston-González 2014, Renjifo et al. 2014). The criteria threshold for Vulnerable are due to extensive fragmentation and remaining habitat quality, additionally this species crosses the threshold for Near Threatened due to the number of known populations with more than a thousand individuals (Renjifo et al. 2014). Ocampo-Peñuela (2016) found that this species would be considered Endangered using IUCN criteria when considering a model of distribution refined by elevation and habitat. Either way, the high levels of conservation concern is is due in part to a limited distribution that is highly fragmented by human activities, with remaining populations susceptible to extirpation and an overall declining population trend (Hilty 1985, Stattersfield and Capper 2000, Renjifo et al. 2014). Parker et al. (1996) has labeled this species of “medium” conservation priority. Because of the small range of habitat, these populations are very susceptible to habitat loss and fragmentation (Collar et al. 1997). Populations appear to be highly local, and observations are infrequent (Stattersfield and Capper 2000, BirdLife International 2019).

Effects of human activity on populations

Habitat loss for the Multicolored Tanager has been extensive and is ongoing, with remaining populations highly fragmented and declining (Hilty 1985, Collar et al. 1997, Angarita and Renjifo 2002, Restall et al. 2006, Hilty 2011). It is estimated that this species has lost 79.3% of its historic range, 81% of potential habitat, with 12% of this loss occurring from 2004-2014 (Sander 2005, Renjifo et al. 2014). Most of this recent habitat loss coincides with areas where this species was relatively abundant (Renjifo et al. 2014). Both Parker et al. (1996) and Renifo (1999) considered Chlorochrysa nitidissima to have a “high” degree of sensitivity to human disturbance relative to other Neotropical birds. The primary reason for the high levels of fragmentation, and the high frequency of species of conservation concern among species that share a similar distribution as the Multicolored Tanager, is that coffee grows very well in the subtropical slopes of the Central Andes, which in turn supports major cities and associated economic development (Donegan and Salaman 1999, Stattersfield and Capper 2000, BirdLife International 2019). Indeed, 16 of 29 range-restricted birds of the Central Andes are considered globally threatened (Stattersfield and Capper 2000). Additional threats are caused by deforestation, road expansion, logging, mining, cattle, and immigration (Fierro-Calderón et al. 2009, Hilty 2011). Populations may be further fragmented and conservation efforts are impeded by illicit crops and armed conflicts in Colombia (Fjeldså et al. 2005).

The economic and cultural significance of this stunning bird is appreciated. This species is a powerful eco-tourism attractant (Winton and Ocampo-Peñuela 2018). Also, it has been the mascot for the Youth World Athletics Championship (Restrepo Moreno 2015). This species has been considered in the design of regional reserve systems and conservation efforts (e.g., Kattan et al. 2006, Fierro-Calderón et al. 2009, Ocampo-Peñuela and Pimm 2014). Some of the remaining areas of suitable habitat have been purchased by conservation organizations. For example, Reserva La Forzosa and Reserva Arrierito Antioqueño were purchased after detection of numerous threatened species of birds including the Multicolored Tanager (Donegan and Salaman 1999). Actions are being taken to create new protected areas and to connect reserved with biological corridors (Toro and Cuervo 2002, Carder 2006, Fierro-Calderón and Johnston-González 2014, Ocampo-Peñuela and Pimm 2014). However, it should be noted that Multicolored Tanagers are not known to use existing corridors between populations (Marín-Gómez et al. 2009).
