Tepui Tinamou
The tepui tinamou (''Crypturellus ptaritepui'') is a type of ground bird found in montane moist forest on tepuis, in southeastern Venezuela.Clements, J (2007) Taxonomy This is a monotypic species.Clements, J (2007) All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds.Davies, S. J. J. F. (2003) Etymology ''Crypturellus'' is formed from two Greek roots: (''kruptos'') meaning ‘covered’ or ‘hidden’ and (''oura'') meaning ‘tail’; the Latin suffix ''-ellus'' is diminutive. Thus, ''Crypturellus'' means ‘little hidden tail’.Gotch, A. F. (1195) Description The tepui tinamou is approximately in length. The top of its head and rear of neck are rufous brown, darker on its back, and dusky below with rufous sheen on its upper breast. The sid ...

John Todd Zimmer
John Todd Zimmer (February 28, 1889 in Bridgeport, Ohio – January 6, 1957 in White Plains, New York) was a leading American ornithologist. A graduate of University of Nebraska-Lincoln, he became interested in both entomology and ornithology. From 1913 he worked as an agricultural adviser in the Philippines and later New Guinea, during which time he created important collections of bird specimens. After his return to America, he joined the staff of the Field Museum of Natural History. In that role, he compiled a ''Catalog of the Ayer Ornithological Library'', and participated in expeditions to Africa and Peru. In 1930 Frank Chapman (ornithologist), Frank Chapman recruited him as Associate Curator of Birds at the American Museum of Natural History in New York City, New York, where he remained for the rest of his life. He made systematic revisions of the taxonomy of the birds of Peru and their relatives in other parts of South America, and in his later years combined this with studi ...

Birds Described In 1945
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have 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 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 furthe ...

Tinamous Of South America
Tinamous () are members of the order Tinamiformes (), and family Tinamidae (), divided into two distinct subfamilies, containing 46 species found in Mexico, Central America, and South America. The word "tinamou" comes from the Galibi term for these birds, ''tinamu''. Tinamous are the only living group of palaeognaths able to fly, and were traditionally regarded as the sister group of the flightless ratites, but recent work places them well within the ratite radiation as most closely related to the extinct moa of New Zealand, implying flightlessness emerged among ratites multiple times. Tinamous first appear in the fossil record in the Miocene epoch. They are generally sedentary, ground-dwelling and, though not flightless, when possible avoid flight in favour of hiding or running away from danger. They are found in a variety of habitats, ranging from semi-arid alpine grasslands to tropical rainforests. The two subfamilies are broadly divided by habitat, with the Nothurinae r ...

Crypturellus
''Crypturellus'' is a genus of tinamous containing mostly forest species. However, there are the odd few that are grassland or steppe tinamous. The genus contains 21 species. Taxonomy The genus ''Crypturellus'' was introduced in 1914 by the British ornithologists Baron Brabourne and Charles Chubb with the Tataupa tinamou as the type species. The genus name combines the Ancient Greek κρυπτός (''kruptós'') meaning "hidden" with οὐρά (''oura'') meaning "tail". The ''-ellus'' is a diminutive so that the name means "small hidden tail". Description ''Crypturellus'' members, like other tinamous, have a cryptic color scheme dominated by browns, buffs, yellows, and greys. Unlike the rest of the family, these birds show some sexual dimorphism: the females are more heavily barred than the males and are also a bit brighter and larger. Range The majority of species occupy forests or rain forests, preferring lower elevations. They range from Uruguay to Mexico. However, the ear ...

Least Concern
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

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 ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, 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 and 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 alpine climate, climate becomes co ...

Bolívar (state)
Bolívar (, ) is one of the 23 States of Venezuela, states of Venezuela. The state capital city is Ciudad Bolívar and the largest city is Ciudad Guayana. Bolívar State covers a total surface area of and as of the 2011 census, had a population of 1,410,964. The state contains Angel Falls.
