George Loddiges
George Loddiges (1784/1786 – 5 May 1846) was a British gardener, artist, and naturalist. He worked in the nursery business established by his father and illustrated nearly 2000 plates of plants in the nursery's own periodical, the Botanical Cabinet published between 1817 and 1833. He also planned a book on the hummingbirds but this was not published. The hummingbird genus ''Loddigesia'' is named after him. George was born in Hackney Central, Hackney, Middlesex. Some give the date as 12 March 1786, while other sources suggest 1784. He was the son of Joachim Conrad Loddiges (c.1738–1826) and Sarah Aldous. Joachim Loddiges was a German-born nurseryman who founded Conrad Loddiges and Sons, one of the largest nurseries in the 1800s. Along with his brother William, George also trained in the trade of plants and the management of nurseries. The family managed special greenhouses and a 9 acre arboretum for tropical plants and were reputed for their collections of palms and orchids. Geor ...

Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boissonneaua
''Boissonneaua'' is a small genus of hummingbirds in the family Trochilidae. They are found in humid Andean forests from western Venezuela to southern Peru. They have a straight black beak, bill, contrasting outer rectrices, and a distinctive habit of quickly lifting both wings up shortly after landing, thereby revealing their rufous underwing Covert (feather), coverts.

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] |
Hawking (birds)
Hawking is a feeding strategy in birds involving catching flying insects in the air. The term usually refers to a technique of sallying out from a perch to snatch an insect and then returning to the same or a different perch, though it also applies to birds that spend almost their entire lives on the wing. This technique is called "flycatching" and some birds known for it are several families of "flycatchers": Old World flycatchers, monarch flycatchers, and tyrant flycatchers. Other birds, such as swifts, swallows, and nightjars, also take insects on the wing in continuous aerial feeding. The term "hawking" comes from the similarity of this behavior to the way hawks take prey in flight, although, whereas raptors may catch prey with their feet, hawking is the behavior of catching insects in the bill. Many birds have a combined strategy of both hawking insects and gleaning them from foliage. Flycatching The various methods of taking insects have been categorized as: gleaning (per ...

Elfin Forest
Dwarf forest, elfin forest, or pygmy forest is an uncommon ecosystem featuring miniature trees, inhabited by small species of fauna such as rodents and lizards. They are usually located at high elevations, under conditions of sufficient air humidity but poor soil. There are two main dwarf forest ecosystem types, involving different species and environmental characteristics: coastal temperate and montane tropical regions. Temperate coastal dwarf forest is common for parts of Southern California. Montane tropical forests are found across tropical highlands of Central America, northern South America and Southeast Asia. There are also other isolated examples of dwarf forests scattered across the world, while the largest dwarf forest is found in the Philippines. High-elevation tropical dwarf forest High-elevation tropical locations in cloud forests contain mossy wet elfin forests due to high-elevation precipitation. These regions are characterized by low rainfall, with most of the wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloudforest
A cloud forest, also called a water forest, primas forest, or tropical montane cloud forest (TMCF), is a generally tropical or subtropical, evergreen, montane, moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level, formally described in the ''International Cloud Atlas'' (2017) as silvagenitus. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the saddles of mountains, where moisture introduced by settling clouds is more effectively retained. Cloud forests are among the most biodiversity rich ecosystems in the world with a large amount of species directly or indirectly depending on them. Other moss forests include black spruce/feathermoss climax forest, with a moderately dense canopy and a forest floor of feathermosses including ''Hylocomium splendens'', ''Pleurozium schreberi'' and ''Ptil ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Pre-Colonial According to recent studies in archaeology, history and anthropology, The Andean Region, Venezuela, Andean region seems to have been inhabited since very remote times (perhaps several thousand years) by unknown groups that have left very few traces. Then, around our era, another ethnic group of great cultural importance arrives in the region, perhaps of Chibcha origin, since they share with these their mythology, funeral and settlement patterns, housing construction, agricultural techniqu ...
