Crimson-rumped Toucanet
The crimson-rumped toucanet (''Aulacorhynchus haematopygus'') is a near-passerine bird in the toucan family Ramphastidae. It is found in Colombia, Ecuador, and Venezuela. Taxonomy and systematics The crimson-rumped toucanet was originally described in the genus '' Pteroglossus''. Two subspecies are recognized, the nominate ''A. h. haematopygus'' ( Gould, 1835) and ''A. h. sexnotatus'' Gould, 1868. Description The crimson-rumped toucanet is long. The nominate subspecies weighs and ''A. h. sexnotatus'' . Their bill is brownish red and black with a vertical white line at the base; the nominate has a larger proportion of black than ''A. h. sexnotatus''. Males and females have the same plumage but females have a shorter bill than males. Adults of both subspecies are mostly green with a gold gloss to the nape and upper back, a red rump, chestnut tips on the central two or three pairs of tail feathers, and bare orange-brown skin around the dark eye. The nominate has blue above ... [...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. Gould then be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest. Description Depending on the forest, the development of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1835
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 ...

Aulacorhynchus
Green toucanets are near-passerine birds from the genus ''Aulacorhynchus'' in the toucan family. They are native to Mexico, and Central and South America. All are found in humid forests and woodlands in highlands, but a few also occur in adjacent lowlands.Short, L. L., & Horne, J. F. M. (2002).

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] |
Allopreening
Preening is a found in birds that involves the use of the beak to position feathers, interlock feather that have become separated, clean plumage, and keep ectoparasites in check. Feathers contribute significantly to a bird's insulation, waterproofing and aerodynamic flight, and so are vital to its survival. Because of this, birds spend considerable time each day maintaining their feathers, primarily through preening. Several actions make up preening behaviour. Birds fluff up and shake their feathers, which helps to "rezip" feather barbules that have become unhooked. Using their beaks, they gather preen oil from a gland at the base of their tail and distribute this oil through their feathers. They draw each contour feather through their bill, nibbling it from base to tip. Over time, some elements of preening have evolved to have secondary functions. Ritualised preening has become a part of some courtship displays, for example. It is also a displacement activity that can occur ...

Loja Province
Loja Province () is one of 24 provinces in Ecuador and shares its southern border on the west with El Oro Province, on the north with El Azuay, and on the east with Zamora-Chinchipe. Founded on its present site in 1548 by Captain Alonso de Mercadillo (Spanish), the site had been previously moved and rebuilt from La Toma due to earthquakes. It also is named as "Cuxibamba Valley", from the Quichua language, which means the "Smiley Valley". Overview Loja is located in a high Andean valley at an elevation of 7,300 feet (2,225 m). It had a population of 448,966 inhabitants at the 2010 census. It is recognized as being a friendly and pleasant city. This was demonstrated when Loja, both the provincial capital and one of the oldest cities in Ecuador, won a community involvement award in 2001 in recognition of the community's ongoing effort to support and to protect the environment. Surrounded by two rivers, the Zamora and Malacatos, Loja has a variety of microclimates. This uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near-passerine
Near passerines and higher land-bird assemblage are terms of traditional, pre-cladistic taxonomy that have often been given to tree-dwelling birds or those most often believed to be related to the true passerines (order Passeriformes) owing to morphological and ecological similarities; the group corresponds to some extent with the Anomalogonatae of Alfred Henry Garrod. Biology All near passerines are land birds. However, molecular data does not support the traditional arrangement; it is now clear that "near passerines" and "higher landbirds" are not synonymous. Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising Passeriformes, Psittaciformes and Falconiformes. Orders Pterocliformes (sandgrouse), Columbiformes (pigeons), Cuculiformes (cuckoos), Caprimulgiformes (nightjars), and Apodiformes (swifts, hummingbirds) are no longer recognized as near passerines. The true near-passerine families are the Psittaciformes (parrots), the Falconiformes (falco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
