Colombian Biodiversity includes 2 species of hummingbirds and flycatcher proposals published in the Journal of ProAves, which are now internationally recognized. We currently have 1903 species of birds in our country, the most biodiverse in birds of the world:
Because of studies published in the 19th edition of the scientific journal of the ProAves , Conserción Colombiana, written by international experts Dr Nigel Collar of BirdLife International and Dr Paul Salaman, of the Rainforest Trust, biometric and morphological variation was assessed, in plumage and vocalizations, of four populations of the Bearded Helmetcrest (Oxypogon guerinii) throughout its range. This species is found in isolated paramos in several parts of the country and Venezuela, each population being very different from one another. The article is available at the following link: The taxonomic and conservation status of the Oxypogon helmetcrests
In the published study, it was proposed to recognize as separate species populations located in the Sierra Nevada de Santa Marta (O. cyanolaemus); Venezuelan Andes (O. lindenii); the Eastern Cordillera of Colombia (O. guerinii) and the Central Cordillera of Colombia (O. stubelii).
Now, a committee of the American Ornithologists’ Union, called the South American Classification Committee (SACC), which has the task of evaluating the systematic (or names and taxonomic treatment) of the birds of South America; deliberated on this work and accepted to treat Oxypogon as four valid species.
Furthermore, other recognized groups, such as the International Ornithological Congress (IOC) and BirdLife International / IUCN, have also accepted this proposal
Photos and details of these species are found below under the following names:
