The Chestnut-bellied Flowerpiercer (Diglossa gloriosissima) is a rare and small tanager, occurring at elevations above 3,000 m. It belongs to the subfamily Diglossinae (“highland tanagers”) and it is one of the 18 species in the genus Diglossa (Burns et al. 2014). This tanager has an overall black back and chest, rufous chestnut belly, and gray shoulder patch. There were no records of the Chestnut-bellied Flowerpiercer from 1965 to 2003; to this day they are known to occur in only 5 localities in Colombia : Cerro Munchique, Paramo Frontino, Cerro Paramillo, Jardin and Farallones del Citara (Restall at al. 2007).
