Great sapphirewing

The great sapphirewing (Pterophanes cyanopterus) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae. It is found in Bolivia, Colombia, Ecuador, and Peru.

The great sapphirewing is the only member of its genus. In the late 1900s it was suggested that Pterophanes be merged into genus Coeligena, but later work showed that those genera are not closely related. The species has three subspecies, the nominate P. c. cyanopterus, P. c. caeruleus, and P. c. peruvianus.

The great sapphirewing has also been called Temminck's sapphirewing, páramo sapphirewing, and simply sapphirewing.

The great sapphirewing is one of the largest hummingbirds; only the two of genus Topaza and the giant hummingbird (Patagona gigas) are larger. It is 15.5 to 19 cm (6.1 to 7.5 in) long including the 3.6 cm (1.4 in) bill. Males weigh between 9.6 and 11.2 g (0.34 and 0.40 oz) and females 8.4 to 11 g (0.30 to 0.39 oz). Both sexes have a small white spot behind the eye. Males of the nominate subspecies have dark shining blue-green upperparts. The wing is mostly shining blue and the tail greenish black. The underparts are also blue-green but somewhat bluer than the upperparts. Nominate females have mostly dark metallic green upperparts with a dusky gray crown. Only the wing coverts are blue; the rest of the wing is dusky. The tail is mostly greenish black with much white on the outermost feathers. The underparts are cinnamon that is mixed with green on the sides.

Males of subspecies P. c. caeruleus have even more and darker blue than the nominate. Females also have more blue, a darker crown, and less white on the outer tail feathers. Males of P. c. peruvianus have more greenish than blue upperparts than the nominate, though the wings have about the same amount of blue. The underparts are also greenish, with a buffy belly. The female's underparts are a less intense cinnamon than the nominate's and it has more white on the outer tail feathers.

The nominate subspecies of great sapphirewing is found in Colombia's Eastern Andes, in the departments of Norte de Santander and Cundinamarca, and slightly into adjoining far western Venezuela. P. c. caeruleus is found in Colombia's Central and Western Andes. P. c. peruvianus is the most widespread; it is found from the Western Andes of Colombia south through Ecuador and Peru to Cochabamba Department in central Bolivia.

The great sapphirewing inhabits the edges of humid evergreen and elfin forest and shrubby slopes with scattered trees. It also occurs well into the páramo, at least seasonally. In Colombia it occurs between 2,600 and 3,600 m (8,500 and 11,800 ft), in Ecuador between 3,000 and 3,600 m (9,800 and 11,800 ft), in Peru between 2,600 and 3,700 m (8,500 and 12,100 ft), and in Bolivia mostly above 3,000 m (9,800 ft).

The great sapphirewing is mostly sedentary, but locally some move to lower elevations during the austral winter.
