El Oro Parakeet (Pyrrhura orcesi) Science Article 2
A new species of parakeet, Pyrrhura orcesi sp. nov., from southwestern Ecuador is described and named the El Oro Parakeet. This species is most closely related to the Maroon-tailed Parakeet (P. melanura). Pyrrhura orcesi is restricted to a narrow band of forest, between ca 600 to 1100 m in elevation, along the western slope of the Ecuadorian Andes. Its range is only ca 100 km in length, and, given the current rate of deforestation in the area, it soon may be threatened with extinction.
