Chaco Owl
The Chaco owl (''Strix chacoensis'') is an owl found in Argentina, Bolivia, and Paraguay. Taxonomy and systematics The Chaco owl was originally described as a species, then quickly reclassified as a subspecies of rufous-legged owl (''Strix rufipes''). A 1995 paper provided strong morphological and vocal evidence that the original treatment as a species in its own right was correct. Later work showed that it is probably more closely related to the rusty-barred owl (''S. hylophila'') than to the rufous-legged. It is monotypic.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S.

Llandudno
Llandudno (, ) is a seaside resort, town and community in Conwy County Borough, Wales, located on the Creuddyn peninsula, which protrudes into the Irish Sea. In the 2011 UK census, the community – which includes Gogarth, Penrhyn Bay, Craigside, Glanwydden, Penrhynside, and Bryn Pydew – had a population of 20,701. The town's name means "Church of Saint Tudno". Llandudno is the largest seaside resort in Wales, and as early as 1861 was being called 'the Queen of the Welsh Watering Places' (a phrase later also used in connection with Tenby and Aberystwyth; the word 'resort' came a little later). Historically a part of Caernarfonshire, Llandudno was formerly in the district of Aberconwy within Gwynedd. History The town of Llandudno developed from Stone Age, Bronze Age and Iron Age settlements over many hundreds of years on the slopes of the limestone headland, known to seafarers as the Great Orme and to landsmen as the Creuddyn Peninsula. The origins in recorded history are wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buenos Aires Province
Buenos Aires (), officially the Buenos Aires Province (''Provincia de Buenos Aires'' ), is the largest and most populous Argentine province. It takes its name from the city of Buenos Aires, the capital of the country, which used to be part of the province and the province's capital until it was federalized in 1880. Since then, in spite of bearing the same name, the province does not include Buenos Aires proper, though it does include all other parts of the Greater Buenos Aires metropolitan area. The capital of the province is the city of La Plata, founded in 1882. It is bordered by the provinces of Entre Ríos to the northeast, Santa Fe to the north, Córdoba to the northwest, La Pampa to the west, Río Negro to the south and west and the Autonomous City of Buenos Aires to the northeast. Uruguay is just across the Rio de la Plata to the northeast, and both are on the coast of the Atlantic Ocean to the east. Almost the entire province is part of the Pampas geographical regio ...

Owls Of South America
Owls are birds from the order Strigiformes (), which includes over 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl. Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except the polar ice caps and some remote islands. Owls are divided into two families: the true (or typical) owl family, Strigidae, and the barn-owl family, Tytonidae. A group of owls is called a "parliament". Anatomy Owls possess large, forward-facing eyes and ear-holes, a hawk-like beak, a flat face, and usually a conspicuous circle of feathers, a facial disc, around each eye. The feathers making up this disc can be adjusted to sharply focus sounds from varying distances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of The Gran Chaco
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 ...

Strix (genus)
''Strix'' is a genus of owls in the typical owl family (Strigidae), one of the two generally accepted living families of owls, with the other being the barn-owl (Tytonidae). Common names are earless owls or wood owls, though they are not the only owls without ear tufts, and " wood owl" is also used as a more generic name for forest-dwelling owls. Neotropical birds in the genus '' Ciccaba'' are sometimes included in ''Strix''. These are medium-sized to large, robustly built, powerful owls. They do not have ear tufts and most are highly nocturnal woodland birds. Most prey on small mammals, birds, and reptiles. Most owls in the genus ''Strix'' can be distinguished from other genera of owls through their hooting vocalization and lack of visible ears. The Latin genus name ''Strix'' referred to a mythical vampiric owl-monster believed to suck the blood of infants. Although the genus ''Strix'' was established for the earless owls by Linnaeus in 1758, many applied the term to other o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 seasonality, seasonal and interannual variations in climate, as well as environmental factor, habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of bird migration, 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 (climate), proxy for ...

Gran Chaco
The Gran Chaco or Dry Chaco is a sparsely populated, hot and semiarid lowland natural region of the Río de la Plata basin, divided among eastern Bolivia, western Paraguay, northern Argentina, and a portion of the Brazilian states of Mato Grosso and Mato Grosso do Sul, where it is connected with the Pantanal region. This land is sometimes called the Chaco Plain. Toponymy The name Chaco comes from a word in Quechua, an indigenous language from the Andes and highlands of South America. The Quechua word ''chaqu'' meaning "hunting land" comes probably from the rich variety of animal life present throughout the entire region. Geography The Gran Chaco is about 647,500 km² (250,000 sq mi) in size, though estimates differ. It is located west of the Paraguay River and east of the Andes, and is mostly an alluvial sedimentary plain shared among Paraguay, Bolivia, and Argentina. It stretches from about 17 to 33°S latitude and between 65 and 60°W longitude, though estimate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
