The San Cristóbal flycatcher (Pyrocephalus dubius), also known as San Cristóbal vermilion flycatcher or least vermilion flycatcher, is an extinct species of flycatcher, closely related to the vermilion flycatcher. It was endemic to San Cristóbal Island in the Galápagos Islands. The taxon was discovered during Charles Darwin's Galapagos voyage in 1835 and described as full species Pyrocephalus dubius by John Gould in 1839.

Taxonomy

The San Cristóbal flycatcher was described as full species Pyrocephalus dubius in 1839 by John Gould. In 1890, Robert Ridgway suggested the new combination Pyrocephalus minimus.[2] Subsequently, it was reclassified as subspecies Pyrocephalus rubinus dubius of the vermilion flycatcher which is widespread in North America and South America. A 2016 study suggests to reinstate the specific status for both Pyrocephalus dubius and the other Galápagos taxon Pyrocephalus nanus because of genetic divergence.[3] It is recognized as a species by some taxonomic authorities, including the International Ornithologists' Union. Others still consider it to be a subspecies of the vermilion flycatcher.

Description

The San Cristóbal flycatcher reaches a length between 10.8 and 11 cm. The crown of the male is glossy dark vermilion red. The underparts are pale red shading to a brighter hue at the throat and a more intensive red at the breast. The chin is reddish shading to white. The lores, the ear coverts and the upperparts are generally dark brown.

Status

During a survey in 1929 ornithologist

avian pox, and the avian malaria.[5] After a long-term-study since 2012, the Durrell Wildlife Conservation Trust described it as "first bird extinction in Galapagos" in June 2016.[6]
