Screaming Piha (16860825812)
The screaming piha (''Lipaugus vociferans'') is a species of passerine bird in the family Cotingidae. It is found in humid forests in the Amazon and tropical parts of the Mata Atlântica in South America. They are most notable for their extraordinarily loud voice. Distribution and habitat The screaming piha is a common bird in the middle and lower parts of the canopy at altitudes below about , or up to in Venezuela and the Andean foothills. Description The screaming piha grows to a length of about . Both sexes have dull grey plumage (wings and tail often somewhat duskier) and the underparts are paler grey. Juveniles are grey tinged with brown or rust. Behavior and ecology The screaming piha is an elusive bird despite its distinctive voice, remaining still for long periods and blending in with tree branches. It is usually solitary, but may sometimes join a mixed species foraging group. Diet and feeding This species feeds mainly on fruits, but also consumes insects, ...

Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a Power, root-power, and field quantities, power or root-power quantity on a logarithmic scale. Two signals whose level (logarithmic quantity), levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 101/20 (approximately ). The strict original usage above only expresses a relative change. However, the word decibel has since also been used for expressing an Absolute scale, absolute value that is relative to some fixed reference value, in which case the dB symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is "#Voltage, V" (e.g., "20 dBV"). As it originated from a need to express power ratios, two principal types of scaling of the decibel are used to provide consistency depending on whether the scaling refer ...

Birds Described In 1820
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 further ...

Lipaugus
''Lipaugus'' is a genus of birds in the family Cotingidae. Taxonomy The genus was introduced in 1828 by the German zoologist Friedrich Boie in 1828. Boie spelled the genus name as ''Lipangus'' but this was corrected to ''Lipaugus''. The name comes from the Greek language, Greek ''lipaugēs'', meaning "dark" or "devoid of light". The type species was designated by George Robert Gray, George Gray in 1840 as the screaming piha. The genus contains nine species. Two former ''Lipaugus'' species are now in the genus'' Snowornis''. The dusky, chestnut-capped, cinnamon-vented, and scimitar-winged pihas may form a Species complex, superspecies.

Cornell Lab Of Ornithology
The Cornell Lab of Ornithology is a member-supported unit of Cornell University in Ithaca, New York, which studies birds and other wildlife. It is housed in the Imogene Powers Johnson Center for Birds and Biodiversity in Sapsucker Woods Sanctuary. Approximately 250 scientists, professors, staff, and students work in a variety of programs devoted to the Lab's mission: interpreting and conserving the Earth's biological diversity through research, education, and citizen science focused on birds. Work at the Lab is supported primarily by its 100,000 members and supporters. The Cornell Lab produces a quarterly publication, ''Living Bird'' magazine, and an electronic newsletter delivered twice per month. It manages numerous participatory science projects and websites, including the Webby Award-winning ''All About Birds''. History The Cornell Lab of Ornithology was founded by Arthur Augustus Allen, Arthur A. Allen, who had lobbied for the creation of the country's first graduate progra ...

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- ...

Lek (mating Arena)
A lek is an aggregation of male animals gathered to engage in competitive displays and courtship rituals, known as lekking, to entice visiting females which are surveying prospective partners with which to mate. It can also refer to a space used by displaying males to defend their own share of territory for the breeding season. A lekking species is characterised by male displays, strong female mate choice, and the conferring of indirect benefits to males and reduced costs to females. Although most prevalent among birds such as black grouse, lekking is also found in a wide range of vertebrates including some teleost, bony fish, amphibians, reptiles, mammals, and arthropods including crustaceans and insects. A classical lek consists of male territories in visual and auditory range of each other. An exploded lek, as seen in the kākāpō (the owl parrot), has more widely separated territories, but still in auditory range. Lekking is associated with an apparent lek paradox, paradox ...

White Bellbird
The white bellbird (''Procnias albus'') is a species of bird in the family Cotingidae. It is the world’s loudest bird, producing vocalizations of up to 125.4 decibels. The specific name (zoology), specific epithet is often spelled ''alba'', but ''albus'' is correct due to the masculine grammatical gender, gender of "''Procnias''". It is found in forests in the Guianas, with small numbers in Venezuela and the Brazilian States of Brazil, state of Pará, as well as Trinidad and Tobago and Panama. As in two other members of ''Procnias'', the males have Wattle (anatomy), wattles, fleshy structures akin to the red skin flap that hangs from the throat of roosters. Description The white bellbird grows to a length of about . The male is pure white with a black bill that has a fleshy black Wattle (anatomy), wattle, sparsely feathered with white feathers, dangling from its top and hanging down the side, usually the right side; the female is an overall Olive (color), olive colour, with ...
