Choco Vireo Vireo masteri

Sections

Discovered as recently as the 1990s, the Choco Vireo is a distinctive and remarkable bird characterized by its prominent yellow supercilium contrasting with the greyish-olive crown and dark eye-stripe, its broad, creamy-white double wingbar, and its creamy-white underparts, with a yellow breast, flanks and vent. The species appears to usually favour primary cloud forest, although in Ecuador it seems more tolerant of slightly degraded areas. This vireo apparently joins mixed-species foraging flocks on a regular basis. To date, it has been found at less than a handful of widely scattered localities in western Colombia, and just two in Ecuador, as far south as Pichincha province. Its apparent scarcity and the dwindling amount of habitat available to the species have led BirdLife International to consider the Choco Vireo as being Endangered. Named for Bernie Master, the species’ discoverers, Paul Salaman and Gary Stiles, decided to auction the rights to the bird’s name in order to raise much-needed money for conservation.
