Foothill Screech Owl
The foothill screech owl (''Megascops roraimae'') is a species of owl in the family Strigidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Guyana, Suriname, and Venezuela. Taxonomy and systematics The foothill screech owl's taxonomy has undergone numerous changes. It has variously been treated as embedded in or a subspecies of the original ''Otus guatemalae'' and then as a subspecies of ''O. vermiculatus'' when that was split from ''O. guatemalae''. In the early 2000s all of the New World members of ''Otus'' were assigned to ''Megascops''.Holt, D. W., R. Berkley, C. Deppe, P. L. Enríquez, J. L. Petersen, J. L. Rangel Salazar, K. P. Segars, K. L.

Osbert Salvin
Osbert Salvin FRS (25 February 1835 – 1 June 1898) was an English naturalist, ornithologist, and herpetologist best known for co-authoring ''Biologia Centrali-Americana'' (1879–1915) with Frederick DuCane Godman. This was a 52 volume encyclopedia on the natural history of Central America. Biography Osbert Salvin was born in Finchley, north London, the second son of the architect Anthony Salvin, of Hawksfold, Sussex. He was educated at Westminster and Trinity Hall, Cambridge, taking his degree in 1857. Shortly afterwards he accompanied his second cousin by marriage, Henry Baker Tristram, in a natural history exploration of Tunisia and eastern Algeria. Their account of this trip was published in '' The Ibis'' in 1859 and 1860. In the autumn of 1857, he made the first of several visits to Guatemala, returning there with Frederick DuCane Godman in 1861. It was during this journey that the ''Biologia Centrali-Americana'' was planned. In 1871 Salvin became editor of '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned specia ...

Birds Described In 1897
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. Bird ...

Megascops
Screech owls are typical owls ( Strigidae) belonging to the genus ''Megascops'' with 23 living species. For most of the 20th century, this genus was merged with the Old World scops owls in ''Otus'', but nowadays it is again considered separately based on a range of behavioral, biogeographical, morphological, and DNA sequence data. Screech owls are restricted to the Americas. Some species formerly placed with them are nowadays considered more distinct (see below for details). Description Similar to other owls, the screech owl females are larger than the males of their species. They have a compact size and shape. They are small and agile, and about 7 to 10 inches tall and have a wingspan around 18 to 24 inches. They have prominent, wide-set feather tufts with bright yellow/green eyes. They have different brownish hues with whitish, patterned underside. This coloration helps them get camouflage against the tree bark. Ecology and behavior Screech owls hunt from perches in ...

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 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 ...

Tepui
A tepui , or tepuy (), is a table-top mountain or mesa found in South America, especially in Venezuela and western Guyana. The word tepui means "house of the gods" in the native tongue of the Pemon, the indigenous people who inhabit the Gran Sabana. Tepuis tend to be found as isolated entities rather than in connected ranges, which makes them the host of a unique array of endemic plant and animal species. Some of the most outstanding tepuis are Auyantepui, Autana, Neblina, and Mount Roraima. They are typically composed of sheer blocks of Precambrian quartz arenite sandstone that rise abruptly from the jungle, giving rise to spectacular natural scenery. Auyantepui is the source of Angel Falls, the world's tallest waterfall. Morphology These table-top mountains are the remains of a large sandstone plateau that once covered the granite basement complex between the north border of the Amazon Basin and the Orinoco, between the Atlantic coast and the Rio Negro.

Guianan Shield
The Guiana Shield (french: Plateau des Guyanes, Bouclier guyanais; nl, Hoogland van Guyana, Guianaschild; pt, Planalto das Guianas, Escudo das Guianas; es, Escudo guayanés) is one of the three cratons of the South American Plate. It is a 1.7 billion-year-old Precambrian geological formation in northeast South America that forms a portion of the northern coast. The higher elevations on the shield are called the Guiana Highlands, which is where the table-like mountains called tepuis are found. The Guiana Highlands are also the source of some of the world's most well-known waterfalls such as Angel Falls, Kaieteur Falls and Cuquenan Falls. The Guiana Shield underlies Guyana (previously British Guiana), Suriname (previously Dutch Guiana) and French Guiana (or Guyane), much of southern Venezuela, as well as parts of Colombia and Brazil. The rocks of the Guiana Shield consist of metasediments and metavolcanics ( greenstones) overlain by sub-horizontal layers of sandston ...

Vermiculation
Vermiculation is a surface pattern of dense but irregular lines, so called from the Latin ''vermiculus'' meaning "little worm" because the shapes resemble worms, worm-casts, or worm tracks in mud or wet sand. The word may be used in a number of contexts for patterns that have little in common. The adjective vermiculated is more often used than the noun. Vermiculation naturally occurs in patterns on a wide variety of species, for example in the feathers of certain birds, for which it may provide either camouflageSee, e.g., Iain Campbell, Sam Woods, Nick Leseberg, ''Birds of Australia: A Photographic Guide'' (2014), p. 110. or decoration. Several species are named after this trait, either in English or by the Latin ''vermicularis''. It also appears in architecture as a form of rustication where the stone is cut with a pattern of wandering lines. In metalwork, vermiculation is used to form a type of background found in Romanesque enamels, especially on chasse reliquary caske ...

Vermiculated Screech Owl
The vermiculated screech owl (''Megascops vermiculatus''), is a species of owl in the family Strigidae. It is found in Costa Rica, Nicaragua, and Panama. Taxonomy and systematics The taxonomy of the vermiculated screech owl is somewhat unsettled. The International Ornithological Committee (IOC) recognizes it as a distinct monotypic species. However, the North American Classification Committee of the American Ornithological Society (AOS/NACC)) and the Clements taxonomy treat it as a subspecies of the Middle American screech owl (''M. guatemalae''). What is now the foothill screech owl (''M. roraimae'') was once considered a subspecies of the vermiculated screech owl. Clements, J. F., T. S. Schulenberg, M. J. Iliff, S. M. Billerman, T. A.
