Pithys Castanea
The white-masked antbird (''Pithys castaneus'') is a Near Threatened species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to Peru. Taxonomy and systematics The white-masked antbird was known only from its type specimen from its discovery in 1937 until 2001 when its status as a species was confirmed. It had been suggested instead to be a hybrid of two antbird species.Lane, D. F., T. Valqui H., J. Alvarez A., J. Armenta, and K. Eckhardt (2006). The rediscovery and natural history of the White-masked Antbird (''Pithys castaneus''). Wilson Journal of Ornithology 118(1):13–22 It shares genus ''Pithys'' with the white-plumed antbird (''P. albifrons''). It has no subspecies. Description The white-masked antbird is about long. The sexes are alike. Adults are mostly bright rufous chestnut. Their crown, nape, lower ear coverts, and the sides of their throat are black.

Jacques Berlioz
Jacques Berlioz (9 December 1891, Paris – 21 December 1975) was a French zoologist and ornithologist, specializing in hummingbirds. He was a grand-nephew of composer Hector Berlioz (1803–1869). Berlioz was born in Paris, where the family home stood behind Sainte-Trinité and took an interest in natural history from his early childhood. The family included many artists and scientists and his grand uncle was the famous composer Hector Berlioz. He studied medicine and pharmaceutical chemistry in which he received a doctorate in 1917. He then worked at the ''Muséum national d'Histoire naturelle'' in Paris as an assistant in the department of entomology, moving to the department of mammals and birds in 1920. He became an assistant curator after some years and a chief curator in 1949 with the title of professor. He continued to work here until his retirement in 1962. Berlioz travelled to Madagascar and Vietnam on collection trips with Jean Delacour between 1925 and 1932. Among hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of Loreto
Loreto () is Peru's northernmost department and region. Covering almost one-third of Peru's territory, Loreto is by far the nation's largest department; it is also one of the most sparsely populated regions due to its remote location in the Amazon Rainforest. Its capital is Iquitos. Geography * Northwest: Ecuador: Sucumbíos Province, Orellana Province, Pastaza Province and Morona-Santiago Province * North: Colombia: Putumayo Department * Northeast: Colombia: Amazonas Department * East: Brazil: Amazonas State and Acre State * South: Ucayali and Huánuco regions * West: San Martín and Amazonas regions Loreto's large territory comprises parts of the High and Low Jungle, and is largely covered with thick vegetation. This territory has wide river flood plains, which are covered with rainwater and usually are swamped in summer. In these flood areas there are elevated sectors called ''restingas'', which always remain above water, even in times of the greatest swellings. There are ...

Endemic Birds Of Peru
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Peruvian Amazonia
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, 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 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 adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pithys
''Pithys'' is a genus of insectivorous passerine binds in the antbird family, Thamnophilidae. The species in this genus are specialist ant-followers that depend on swarms of army ants to flush insects and other arthropods out of the leaf litter. The genus was erected by the French ornithologist Louis Pierre Vieillot in 1818. The type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen ... is the white-plumed antbird (''Pithys albifrons'').

Antbirds
The antbirds are a large passerine bird family (biology), family, Thamnophilidae, found across subtropical and tropical Central and South America, from Mexico to Argentina. There are List of antbirds, more than 230 species, known variously as antshrikes, antwrens, antvireos, fire-eyes, bare-eyes and bushbirds. They are related to the antthrushes and antpittas (family Formicariidae), the tapaculos, the gnateaters and the Ovenbird (family), ovenbirds. Despite some species' common names, this family is not closely related to the wrens, vireos or shrikes. Antbirds are generally small birds with rounded wings and strong legs. They have mostly sombre grey, white, brown and rufous plumage, which is sexual dimorphism, sexually dimorphic in pattern and colouring. Some species communicate warnings to rivals by exposing white feather patches on their backs or shoulders. Most have heavy beak, bills, which in many species are hooked at the tip. Most species live in forests, although a few ar ... [...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] |
Army Ant
The name army ant (or legionary ant or ''marabunta'') is applied to over 200 ant species in different lineages. Because of their aggressive predatory foraging groups, known as "raids", a huge number of ants forage simultaneously over a limited area. Another shared feature is that, unlike most ant species, army ants do not construct permanent nests; an army ant colony moves almost incessantly over the time it exists. All species are members of the true ant family, Formicidae, but several groups have independently evolved the same basic behavioural and ecological syndrome. This syndrome is often referred to as "legionary behaviour", and may be an example of convergent evolution. Most New World army ants belong to the genera ''Cheliomyrmex'', ''Neivamyrmex'', ''Nomamyrmex'', ''Labidus'', and ''Eciton''. The largest genus is ''Neivamyrmex'', which contains more than 120 species; the most predominant species is ''Eciton burchellii''; its common name "army ant" is considered to b ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ant Follower
Ant followers are birds that feed by following swarms of army ants and take prey flushed by those ants. The best-known ant-followers are 18 species of antbird in the family Thamnophilidae, but other families of birds may follow ants, including thrushes, chats, ant-tanagers, cuckoos, motmots, and woodcreepers. Ant followers may be obligate, meaning that they derive most of their diet by following ant swarms, or non-obligate, meaning they derive only some of their diet from this behaviour. Some species may feed extensively at ant swarms yet may not be obligate ant followers, being able to and regularly feeding away from the swarms as well. Many species of tropical ants form large raiding swarms, but the swarms are often nocturnal or raid underground. While birds visit these swarms when they occur, the species most commonly attended by birds is the Neotropical species ''Eciton burchellii'', which is both diurnal and surface-raiding. It was once thought that attending birds were a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazonas (Peruvian Department)
Amazonas () is a department and region in northern Peru bordered by Ecuador on the north and west, Cajamarca on the west, La Libertad on the south, and Loreto and San Martín on the east. Its capital is the city of Chachapoyas. With a landscape of steep river gorges and mountains, Amazonas is the location of Kuelap, a huge stone fortress enclosing more than 400 stone structures; it was built on a mountain about 3,000 meters high, starting about 500 AD and was occupied to the mid-16th century. It is one of Peru's major archeological sites. Geography The department of Amazonas consists of regions covered by rainforests and mountain ranges. The rainforest zone predominates (72.93%) and it extends to the north over its oriental slope, up to the border with Ecuador in the summits of the Cordillera del Cóndor. The mountain range zone is located in the southern provinces of the Amazonas Region and it only includes 27.07% of its whole territorial surface. One of the factors th ...

Near Threatened Species
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.
