Birds Described In 1842
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 swimming. Birds ...

Chaetocercus
''Chaetocercus'' is a genus of hummingbirds in the family Trochilidae. Taxonomy The genus ''Chaetocercus'' was introduced in 1855 by the English zoologist George Robert Gray with the rufous-shafted woodstar as the type species. The name is a combination of the Ancient Greek words ''khaitē'', meaning "hair" and ''kerkos'', meaning "tail". The genus contains six species: *White-bellied woodstar (''Chaetocercus mulsant'') *Little woodstar (''Chaetocercus bombus'') *Gorgeted woodstar (''Chaetocercus heliodor'') *Santa Marta woodstar (''Chaetocercus astreans'') * Esmeraldas woodstar (''Chaetocercus berlepschi'') *Rufous-shafted woodstar (''Chaetocercus jourdanii'') All these species, except for the rufous-shafted woodstar, were formerly placed in the genus ''Acestrura''. In 1999 Karl-Ludwig Schuchmann remarked in the ''Handbook of the Birds of the World The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edici ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenology
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonality, seasonal and interannual variations in climate, as well as environmental factor, habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of bird migration, migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies. In the scientific literature on ecology, the term is used more generally to indicate the time frame for any seasonal biological phenomena, including the dates of last appearance (e.g., the seasonal phenology of a species may be from April through September). Because many such phenomena are very sensitive to small variations in climate, especially to temperature, phenological records can be a useful proxy (climate), proxy for ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cochabamba Department
Cochabamba ( ay, Quchapampa Jach'a Suyu, es, Departamento de Cochabamba , qu, Quchapampa Suyu), from Quechua ''qucha'' or ''qhucha'', meaning "lake", ''pampa'' meaning "plain", is one of the nine departments of Bolivia. It is known to be the "granary" of the country because of its variety of agricultural products from its geographical position. It has an area of 55,631 km2. Its population in the 2012 census was 1,758,143. Its capital is the city of Cochabamba, known as the "City of Eternal Spring" and "The Garden City" because of its spring-like temperatures all year. History The Cochabamba valley was inhabited for over a thousand years due to its fertile productive soils and climate. Archaeological evidence suggests that the initial valley inhabitants were of various ethnic indigenous groups. Tiwanaku, Tupuraya, Mojocoya, Omereque and Inca inhabited the valley at various times before the Spanish arrived. The first Spanish inhabitant of the Valley was Garci Ruiz de Orell ...

Gorget (bird)
A gorget is a patch of colored feathers found on the throat or upper breast of some species of birds. It is a feature found on many male hummingbirds, particularly those found in North America; these gorgets are typically iridescent. Other species, such as the purple-throated fruitcrow and chukar partridge, also show the feature. The term is derived from the gorget used in military armor to protect the throat. Feather wear and exposure to the sun can produce changes in the apparent color of iridescent gorget feathers. For example, fresh gorget feathers on the Anna's hummingbird are rose red; these fade to a coppery bronzy color with age. Functions A number of social functions have been suggested for the gorget. It may aid in mate attraction or in resource defense. It may signal social status or allow species to identify conspecifics. Among hummingbirds, gorgets are typically found only on males. In the rare instances where they are found on females, they appear to serve primar ... [...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 rate ...
