Wedge-tailed sabrewing
The wedge-tailed sabrewing (Pampa pampa) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Belize, Guatemala, Mexico, and possibly Honduras. Taxonomy and systematics The taxonomy of the wedge-tailed sabrewing is unsettled. It was formerly placed in the genus Campylopterus. A molecular phylogenetic study published in 2014 found that the genus Campylopterus was polyphyletic. In the revised classification to create monophyletic genera, the wedge-tailed sabrewing was moved to the resurrected genus Pampa by some taxonomic systems. The International Ornithological Committee (IOC) adopted the split of C. curvipennis into three species of sabrewings, the wedge-tailed (Pampa pampa), curve-winged (P. curvipennis), and long-tailed (P. excellens). It treats each as monotypic. The North American Classification Committee of the American Ornithological Society and the Clements taxonomy adopted long-tailed sabrewing as P. excellens. They adopted the wedge-tailed as P. curvipennis and assigned IOC's wedge-tailed and curve-winged to it as subspecies. BirdLife International's Handbook of the Birds of the World (HBW) was the most conservative. It retained the binomial Campylopterus curvipennis for the wedge-tailed sabrewing with the three taxa as subspecies. This article follows the IOC treatment of a monotypic wedge-tailed sabrewing.
