Augastes Lumachella
The hooded visorbearer (''Augastes lumachella'') is a small species of hummingbird in the family Trochilidae. Endemic to the east Brazilian state of Bahia, it is found only at higher altitudes in the Chapada Diamantina region. The species is sexually dimorphic. The male is an iridescent bronzy-green overall, with black on his and the sides of his head. His forehead and throat are a glittering green shading to bluish-green at the lower edge and narrowly bordered by black. The female is bronzer, with a green crown and brown sides to her head. Her throat is less colorful than the male's, and she lacks iridescence on her forehead. Both sexes have crimson tails and a narrow white breast band, the male with a brilliantly iridescent golden-orange spot in the center, at the lower edge of his gorget. It resides in the campo rupestre, an arid, high-elevation area characterized by rocky outcrops, poor soils, open habitats, and harsh climatic conditions. There, it feeds primarily on nectar, ...

Hyacinth Visorbearer
The hyacinth visorbearer (''Augastes scutatus'') is a species of hummingbird in the family Trochilidae. It is endemic to Brazil. Taxonomy and systematics The hyacinth visorbearer shares its genus with only one other species, the hooded visorbearer (''A. lumachella''). It has three subspecies, the nominate ''A. s. scutatus'', ''A. s. ilseae'', and ''A. s. soaresi''. The subspecies are very similar and "might be better treated as monotypic."Schuchmann, K.L. and G. M. Kirwan (2020). Hyacinth Visorbearer (''Augastes scutatus''), version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie, and E. de Juana, Editors).

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
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, ...

Hooded Visorbearer Augastes Lumachella (cropped)
A hood is a kind of headgear that covers most of the head and neck, and sometimes the face. Hoods that cover mainly the sides and top of the head, and leave the face mostly or partly open may be worn for protection from the environment (typically cold weather or rain), for fashion, as a form of traditional dress or uniform, or in the case of knights, an armoured hood is used for protection against bladed weapons. In some cases, hoods are used to prevent the wearer from seeing where they are going (e.g., in cases where a prisoner is hooded). Hoods with eye holes may be used for religious purposes to prevent the wearer from being seen. In the case of Ku Klux Klan members, terrorists, or criminals such as robbers, a hood with eye holes helps prevent identification. Etymology The word traces back to Old English ''hod'' "hood," from Proto-Germanic *''hodaz'' (cf. Old Saxon, Old Frisian ''hod'' "hood," Middle Dutch ''hoet'', Dutch ''hoed'' "hat," Old High German ''huot'' "helmet, hat, ...
