Topaz (hummingbird)
The topazes are two species of hummingbirds in the genus ''Topaza''. They are found in humid forests in the Amazon Basin. Males are by far the largest hummingbirds in their range – the giant hummingbird of the Andes is the only larger species in the family. Males have a total length of about , although this includes their elongated rectrices. They are colourful, being mainly strongly iridescent golden and crimson with a black hood and a green throat. Females lack the elongated rectrices and have a mainly green plumage. Taxonomy The genus ''Topaz'' was introduced by the English zoologist George Robert Gray in 1840 with the crimson topaz as the type species. The genus contains two species, the crimson topaz and the fiery topaz. Although generally considered to be distinct species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fiery Topaz
The fiery topaz (''Topaza pyra'') is a species of hummingbird in the family Trochilidae. It has brilliant iridescent plumage and resides in northern South America, where it consumes nectar and insects. Taxonomy and systematics The genus ''Topaza'' and its sister genus ''Florisuga'' form the topazes group, which together with the hermits represent the most ancient branch within the family Trochilidae. The Topazes group contains some of the largest hummingbirds in the family, adult males measuring up to 23 cm and weighing up to 12 g. Topazes as a group are estimated to have diverged as a separate lineage from all other hummingbirds around 21.5 Ma, whereas the most recent common ancestor of ''Topaza'' and ''Florisuga'' lived approximately 19 Ma. Two morphospecies are recognized within ''Topaza'': ''T. pyra'', and the crimson topaz, ''T. pella''. The species status of ''T. pyra'' has been challenged by some authors, who consider this genus to be monotypic. Arguments for and a ...

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. Gould then be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trochilidae - Topaza Pyra
Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae. With about 361 species and 113 genera, they occur from Alaska to Tierra del Fuego, but the vast majority of the species are found in the tropics around the equator. They are small birds, with most species measuring in length. The smallest extant hummingbird species is the bee hummingbird, which weighs less than . The largest hummingbird species is the giant hummingbird, weighing . They are specialized for feeding on flower nectar, but all species also consume flying insects or spiders. Hummingbirds split from their sister group, the swifts and treeswifts, around 42 million years ago. The common ancestor of extant hummingbirds is estimated to have lived 22 million years ago in South America. They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to humans. They hover in mid-air at rapid wing-flapping rates, w ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of '' Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
