ACEVEDO-CHARRY, ORLANDO A  and  ECHEVERRI-MALLARINO, LAURA. Notes of Records about Yellow-Green Vireo (Vireo flavoviridis: Vireonidae) at the Sabana de Bogotá, Cundinamarca (Colombia). Acta biol.Colomb. [online]. 2013, vol.18, n.3, pp.517-522. ISSN 0120-548X.

The Yellow-green Vireo (Vireo flavoviridis) is migrant bird specie, previously non reported to Cundinamarca Department. Distribution known in Colombia only includes localities below 1500 masl. Two individuals of the Yellow-green Vireo were observed at 2600 masl in the Universidad Nacional de Colombia Bogotá Campus, at the Sabana de Bogotá in Cundinamarca Department in 2011. In addition, we found 18 unpublished records for this species in the Cundinamarca Department above 2500 masl. Ten records were museum specimens (Instituto de Ciencias Naturales de la Universidad Nacional de Colombia, Vertebrate collection (Ornitology) Universidad de los Andes and Instituto de Investigación en Recursos Biológicos Alexander von Humboldt Museum), and the other eight were birdwatching records. The oldest record was in 1964, but the great majority of records were collected between 2008 and 2013. We consider that the Yellow-green Vireo has been unnoticed in the Cundinamarca Department because of its morphological similarities with the Red-eye Vireo (V. olivaceus). Furthermore, the lack of review of scientific collections, and the deposition of specimens discontinuous there, make gap information about biodiversity distribution. Apparently, Yellow-green Vireo could be more common than expected above 1500 m during its migration, such as it was observed in at Cundinamarca Department.
