San Cristóbal Flycatcher
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''. 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. It is recognized as a spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor.
