The dusky starfrontlet (''Coeligena orina'') is a hummingbird species in the subfamily Trochilinae. It is found only at high altitudes in the Cordillera Occidental of Colombia, and was first discovered on Páramo de Frontino.〔Krabbe ''et al.'' (2005)〕 Its status was mysterious for a long time as it was only known from a few museum specimens; it was often held to be a mutant or color morph of some other species of ''Coeligena''. When it was rediscovered in 2004, in what is now the Colibri del Sol Bird Reserve, its status as a distinct species was confirmed. Although this bird was listed as a species of Least Concern in the IUCN Red List for many years, it became evident that it was close to extinction, and its status was upgraded to Critically Endangered in the 2007 Red List issue.〔BLI (2007, 2008)〕 ==Footnotes== ==References== * BirdLife International (BLI) (2007): (Dusky Starfrontlet - BirdLife Species Factsheet ).
