Dusky Starfrontlet
The dusky starfrontlet (''Coeligena orina''), also known as glittering starfrontlet, is an Endangered species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae. It is endemic to a few small areas in western Colombia.HBW and BirdLife International (2020) ''Handbook of the Birds of the World and BirdLife International digital checklist of the birds of the world'' Version 5. Available at: http://datazone.birdlife.org/userfiles/file/Species/Taxonomy/HBW-BirdLife_Checklist_v5_Dec20.zip xls zipped 1 MBretrieved 27 May 2021 Taxonomy and systematics The dusky starfrontlet was originally known from a single museum specimen collected in 1951 and described as a full species in 1953. In 1988 its status was reassessed as a subspecies of golden-bellied starfrontlet (''Coeligena bonapartei''). It was rediscovered in 2004, in what is now the Colibri del Sol Bird Reserve, and additional specimens confirmed its identity as a species. It and the buff-winged starfron ...

Alexander Wetmore
Frank Alexander Wetmore (June 18, 1886 – December 7, 1978) was an American ornithologist and avian paleontologist. He was the sixth Secretary of the Smithsonian Institution. He was also an elected member of both the American Philosophical Society and the United States National Academy of Sciences. Early life and education The son of a physician, Frank Alexander Wetmore was born in North Freedom, Wisconsin. Developing an interest in birds at an early age, he made his first field journal entry (a pelican seen while on vacation in 1894) at the age of eight. By 1900, Wetmore published his first paper "My Experience with a Red-headed Woodpecker," in the magazine Bird-Lore. To further his education Wetmore enrolled at the University of Kansas in 1905. During his studies there he did a stint as an assistant in the University Museum, under the direction of Charles D. Bunker.

Las Orquídeas National Natural Park
Las Orquídeas National Natural Park (Spanish: ''Parque Nacional Natural Las Orquídeas'' or ''PNN Las Orquídeas'') is a national park in the Cordillera Occidental, Colombia. Established in 1974, the park encompasses on the western slopes of Colombia's Cordillera Occidental. The park covers a large elevational range (300–3,450 m). The climate is generally humid with an annual rainfall of 3,000-4,000 mm, dropping to 2,500 mm at highest elevations, and ranges from tropical lowland to alpine. The range in elevation and climate creates a diversity of plant communities, including lowland rainforest (ca. 300–1,000 m), premontane forest (ca. 1,000–2,000 m), montane forest (ca. 2,000–3,200 m), and high-elevation páramo Páramo () may refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America.

Birds Of The Colombian Andes
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. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, 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 buildin ...

Tatamá National Natural Park
Tatamá National Natural Park (Spanish: ''Parque Nacional Natural Tatamá'' or ''PNN Tatamá'') is a national park in the Cordillera Occidental, Colombia. Established in 1987, the park encompasses of primary west-Andean tropical and subtropical rainforest, temperate cloud forest, and páramo habitat in an area that spans the departments of Risaralda, Chocó and Valle del Cauca, within the Chocó bioregion. The protected area is of high scientific interest because of its rich biodiversity and the unique state of conservation of its ecosystems. The park is home to tributaries of the San Juan and Cauca Rivers and, in its highest elevation area, to Páramo Tatamá, which along Frontino and El Duende, represents one of the only three páramos in Colombia that have not been altered by humans. Cerro Tatamá, the highest peak in the Cordillera Occidental, reaching an elevation of , lies within the park. Flora and fauna Over 560 species of orchids can be found in the park, many ...

Phenology
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of 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 for temperature in historical climatology, especially in the ...

Psocoptera
Psocoptera () are a paraphyletic group of insects that are commonly known as booklice, barklice or barkflies. The name Psocoptera has been replaced with Psocodea in recent literature, with the inclusion of the former order Phthiraptera into Psocodea (as part of the suborder Troctomorpha). They are often regarded as the most primitive of the paraneopterans. There are more than 5,500 species in 41 families in three suborders. Many of these species have only been described in the early twenty-first century. They range in size from in length. The species known as booklice received their common name because they are commonly found amongst old books—they feed upon the paste used in binding. The barklice are found on trees, feeding on algae and lichen. Etymology Their name originates from the Greek word ψῶχος (''psokhos''), meaning " gnawed" or " rubbed" and πτερά (''ptera''), meaning " wings".

Páramo
Páramo () may refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". A narrower term classifies the páramo according to its regional placement in the northern Andes of South America and adjacent southern Central America. The páramo is the ecosystem of the regions above the continuous forest line, yet below the permanent snowline. It is a "Neotropical high mountain biome with a vegetation composed mainly of giant rosette plants, shrubs and grasses". According to scientists, páramos may be "evolution, evolutionary hot spots", meaning that they are among the fastest evolving regions on Earth. Location The Northern Andean Páramo global ecoregion includes the Cordillera Central páramo (Ecuador, Peru), Santa Marta páramo (Colombia), Cordillera de Merida páramo (Venezuela) and Northern Andean páramo (Colombia, Ec ...

Ecotone
An ecotone is a transitional area between two plant communities, where these meet and integrate. Examples include areas between grassland and forest, estuaries and lagoon, freshwater and sea water etc. An ecotone may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems). An ecotone may appear on the ground as a gradual blending of the two communities across a broad area, or it may manifest itself as a sharp boundary line. Etymology The word ''ecotone'' was coined (and its etymology given) in 1904 in "The Development and Structure of Vegetation" (Lincoln, Nebraska: Botanical Seminar) by Frederic E. Clements. It is formed as a combination of ''ecology'' plus ''-tone'', from the Greek ''tonos'' or tension – in other words, a place where ecologies are in tension. Features There are several distinguishing features of an ecotone. First, an ecotone can have a sharp vegetation transition, wi ...

Elfin Forest
A "natural National Park in the Philippines, a UNESCO World Heritage Site file:Mount Kemiri (8187817161).jpg, An elfin forest in Sumatra's Gunung Leuser National Park 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.
