Aglaeactis
''Aglaeactis'' is a genus of hummingbird 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 aro ...s in the family Trochilidae. It contains the following species: Territories Shining sunbeam territories are characterized by highly utilized central core areas with high overall use, but low foraging activity. These territories are usually those associated with structural complexity like canopy coverings, vegetation densities, and ideal nesting/roosting sites. High canopy heights and adequate vegetation densities allow these hummingbirds to effectively transmit auditory and visual signals. More exposed and elevated perches are usually favored. These birds pick the most ideal territories to avoid predators and defend their territories. References Bird genera Taxonomy article ...

White-tufted Sunbeam
The white-tufted sunbeam (''Aglaeactis castelnaudii'') is a species of hummingbird in the family Trochilidae. It is found only in Peru. Its natural habitats are subtropical or tropical moist montane forest and subtropical or tropical high-altitude shrubland. Description An adult white-tufted sunbeam is approximately 12 cm in height and weighs 7- 8.5 g. The bill is straight and black and there is a notable patch of white feathers directly under the chin on the breast. The rest of the body is described as tawny and darkly-colored. There are iridescent feathers on the back of the bird that are most noticeable in flight and while hovering. Males and females of the species exhibit subtle sexual dimorphism. Males are fuscous-black on their upper backs with a magenta reflection on their rump and lower back. Their tails are forked. The belly, side, and neck of a male are dull brown. The throat and pectoral band are blackish in color. True to their name, there is a white feather tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Purple-backed Sunbeam
The purple-backed sunbeam (''Aglaeactis aliciae'') is a bird species in the family Trochilidae. It is found only in Peru. Its natural habitats are subtropical or tropical high-altitude shrubland and plantations. It is threatened by habitat loss. It was formerly classified as Critically Endangered by the IUCN. But new research has shown that although hardly any natural habitat is left, this species is still a bit more numerous than it was believed. Consequently, it is downlisted to Endangered status in 2008 and once again to Vulnerable in 2020.BLI (2008) Biology The unique shoulder structure of hummingbirds allows the wings to beat tremendously fast in a figure eight motion, allowing the birds to maintain a hovering motion at the same time as feeding, with up to 200 wing beats per second. Due to this highly energetic behavior, hummingbirds feed almost solely on nectar (carbohydrate-rich sugar secretions of plants), feeding on as many as 1,000 to 2,000 flowers a day. Hummingbird ...

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.

Species
In biology, a species is the basic unit of Taxonomy (biology), 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 which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hummingbird
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 ra ...

Bird Genera
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
