Santa Marta sabrewing

Campylopterus phainopeplus has at times been placed in genus Saepiopterus. It is monotypic. ==Description==

The Santa Marta sabrewing is about long. Both sexes have a decurved black bill, with the female's having more curvature, and both have a white spot behind the eye. Males' upperparts are glittering emerald green. They have a black face; their throat and breast are iridescent blue and the rest of their underparts dark green. Their tail is dark steely blue. The female has shining green upperparts and mostly grayish white underparts with green flanks and undertail coverts. Its tail is mostly green with grayish tips on the outermost pair of feathers. ==Distribution and habitat==

The Santa Marta sabrewing is known only from the eastern slopes of the Sierra Nevada, in the highlands of the Guatapurí basin, west of Valledupar in northern Colombia. Because it is far from Santa Marta, and it is a endemic to the most important basin in department of Cesar, a proposal to change its English standard name to Guatapurí sabrewing is being discussed. It inhabits the edges of humid forest, plantations (especially of bananas), and bushy páramo. In elevation it ranges from . ==Behavior==

Movement The Santa Marta sabrewing spends the dry season of February to May below and moves higher, even as far as the snow line, during the June to October wet season. However, it is likely not as migratory as previously suspected. Feeding Almost nothing is known about the Santa Marta sabrewing's feeding strategy or diet. It has been documented feeding on flowering banana (Musa), Calliandra trees, Erythrina trees, and Malvaviscus flowers, specifically Malvaviscus concinnus. Is it also territorial. Breeding Santa Marta sabrewings in breeding condition have been found between April and June, and males have been seen displaying in June and July. Nothing else is known about the species' breeding phenology and its nest has not been described. Vocalization As of mid-2022 only one recording of the Santa Marta sabrewing is known. It makes "a plaintive double 'twit-twit', both in flight and display." ==Status==

. The IUCN originally assessed the Santa Marta sabrewing as Near Threatened, then in 2000 as Endangered, and since 2020 as Critically Endangered. It has a very small range and is thought to number fewer than 50 mature individuals. About 85% of the original vegetation within its range has been destroyed by logging and conversion to agriculture, grazing, and human habitation. What remains is degraded and fragmented. Further losses are expected due to human activity and climate change. The latter is causing the dry season to expand which increases the risk of fire. Until about 1900 the Santa Marta Sabrewing was described as fairly common, and it was recorded intermittently until 1946. ==References==
