Orange-fronted Plushcrown
The orange-fronted plushcrown (''Metopothrix aurantiaca'') is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, G. Del-Rio, A. Jaramillo, D. F. Lane, M. B. Robbins, F. G. Stiles, and K. J. Zimmer. Version 28 September 2023. Species Lists of Birds for South American Countries and Territories. https://www.museum.lsu.edu/~Remsen/SACCCountryLists.htm retrieved October 20, 2023 Taxonomy and systematics The orange-fronted plushcrown is the only member of its genus and has no subspecies. Its plumage is so unlike that of most members of family Furnariidae that many authors have questioned whether it belongs there. Genetic data show that it and the two species of genus ''Xenerpestes'' are sisters, and they in turn are sisters to the pink-legged graveteiro (''Acrobatornis fonsecai'').Remsen, J. V., Jr., J. I.

Philip Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River, canoeing down it to the Mississippi. Sclater w ...

Maxilla
The maxilla (plural: ''maxillae'' ) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw. Structure In humans, the maxilla consists of: * The body of the maxilla * Four processes ** the zygomatic process ** the frontal process of maxilla ** the alveolar process ** the palatine process * three surfaces – anterior, posterior, medial * the Infraorbital foramen * the maxillary sinus * the incisive foramen Articulations Each maxilla articulates with nine bones: * two of the cranium: the frontal and ethmoid * seven of the face: the nasal, zygomatic, lacrimal, ...

Mixed-species Feeding Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.

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] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in ...

Várzea Forest
A várzea forest is a seasonal floodplain forest inundated by whitewater rivers that occurs in the Amazon biome. Until the late 1970s, the definition was less clear and várzea was often used for all periodically flooded Amazonian forests. Although sometimes described as consisting only of forest, várzea also contains more open, seasonally flooded habitats such as grasslands, including floating meadows. Description Along the Amazon River and many of its tributaries, high annual rainfall that occurs mostly within a rainy season results in extensive seasonal flooding of areas from stream and river discharge. The result is a rise in water level, with nutrient rich waters. The Iquitos várzea ecoregion covers the margins of the upper Amazon and its tributaries. Further down are the Purus várzea in the middle Amazon, the Monte Alegre várzea and Gurupa várzea on the lower Amazon and the Marajó várzea at the mouth of the Amazon. The Marajó várzea is affected by both fresh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Purus River
The Purus River (Portuguese: ''Rio Purus''; Spanish: ''Río Purús'') is a tributary of the Amazon River in South America. Its drainage basin is , and the mean annual discharge (hydrology), discharge is . The river shares its name with the Alto Purús National Park and the Purús Province (and its conformed Purús District), one of the four provinces of Peru in the Ucayali Region. Geography The Purus River rises in Peru. It defines the boundary between Peru and Brazil in the centre of the state of Acre (state), Acre, then runs for a short distance along the boundary of the Santa Rosa do Purus National Forest, a sustainable use conservation unit created in 2001 after it is joined by the Santa Rosa River (Acre), Santa Rosa River. It then flows north east through Manoel Urbano It runs through a continuous forest at the bottom of the great depression, lying between the Madeira River, which skirts the edge of the Brazilian sandstone plateau, and the Ucayali River, which hugs the ba ...

Juruá River
The Juruá River (Portuguese ''Rio Juruá''; Spanish ''Río Yuruá'') is a southern affluent river of the Amazon River west of the Purus River, sharing with this the bottom of the immense inland Amazon depression, and having all the characteristics of the Purus as regards curvature, sluggishness and general features of the low, half-flooded forest country it traverses. For most of its length the river flows through the Purus várzea ecoregion. This is surrounded by the Juruá-Purus moist forests ecoregion. It rises among the Ucayali highlands, and is navigable and unobstructed for a distance of above its junction with the Amazon. It has a total length of approximately , and is one of the longest tributaries of the Amazon. The Médio Juruá Extractive Reserve, created in 1997, is on the left bank of the river as it meanders in a generally northeast direction through the municipality of Carauari. The lower Juruá River forms the western boundary of the Baixo Juruá Extractiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beni Department
Beni (), sometimes El Beni, is a northeastern department of Bolivia, in the lowlands region of the country. It is the second-largest department in the country (after Santa Cruz), covering 213,564 square kilometers (82,458 sq mi), and it was created by supreme decree on November 18, 1842, during the administration of General José Ballivián. Its capital is Trinidad. Population With a population of 420,000 (2006 census), Beni is the second least-populated of the nine departments of Bolivia, after Pando. Although Beni is rich in natural resources, the poverty level of its inhabitants is high, mainly as a result of centuries of exploitation of native populations by European-descended elites. The main economic activities are agriculture, timber, and cattle. In addition, an underground economy linked to illegal narcotics activities flourished in the area during the last decades of the 20th century, with many cocaine laboratories hidden behind the façade of remote cattle ranch ...

Amazonas (Colombian Department)
Amazonas () is a department of Southern Colombia in the south of the country. It is the largest department in area while having the third smallest population among the departments. Its capital is Leticia and its name comes from the Amazon River, which drains the department. Toponymy The department name comes from the name of the Amazon River. The river was named by the Spanish explorer Francisco de Orellana (1511–1546), who, on his voyage of exploration, said he was attacked by "fierce females" who looked like Amazons of the Greek mythology; however, the existence of a female warrior tribe in that time hasn't been demonstrated and it is possible that they were long-haired Native American warriors who impressed the conqueror, who called the jungle and the river with the name of Amazon. Demographics The following ethnic groups are found in the department: Bora, Cocama, Macuna, Mirana, Okaina, Ticunas, Tucano, Uitoto, Yagua, and Yucuna, among others. These groups are more ...

Putumayo Department
Putumayo () is a department of Southern Colombia. It is in the south-west of the country, bordering Ecuador and Peru. Its capital is Mocoa. The word ''putumayo'' comes from the Quechua languages. The verb ''p'utuy'' means "to spring forth" or "to burst out", and ''mayu'' means river. Thus it means "gushing river". History Originally, the southwestern area of the department belonged to the Cofán Indians, the northwestern to the Kamentxá Indians, the central and southern areas to tribes that spoke Tukano languages (such as the Siona), and the eastern to tribes that spoke Witoto languages. Part of the Kamentxá territory was conquered by the Inca Huayna Cápac in 1492, who, after crossing the Cofán territory, established a Quechua population on the valley of Sibundoy, known today as Ingas. After the Inca defeat in 1533, the region was invaded by the Spanish in 1542, and from 1547 was administered by Catholic missions. The current territory of Putumayo was linked ...
