Black-backed Grosbeak
The black-backed grosbeak (''Pheucticus aureoventris'') is a bird in the family Cardinalidae, the cardinals or cardinal grosbeaks. It is found in Argentina, Brazil, Bolivia, Colombia, Ecuador, Paraguay, Peru, and Venezuela. They are often kept as cagebirds.Brewer, D. and E. de Juana (2020).

Alcide D'Orbigny
Alcide Charles Victor Marie Dessalines d'Orbigny (6 September 1802 – 30 June 1857) was a French naturalist who made major contributions in many areas, including zoology (including malacology), palaeontology, geology, archaeology and anthropology. D'Orbigny was born in Couëron (Loire-Atlantique), the son of a ship's physician and amateur naturalist. The family moved to La Rochelle in 1820, where his interest in natural history was developed while studying the marine fauna and especially the microscopic creatures that he named "foraminiferans". In Paris he became a disciple of the geologist Louis Cordier, Pierre Louis Antoine Cordier (1777–1861) and Georges Cuvier. All his life, he would follow the theory of Cuvier and stay opposed to Lamarckism. South American era D'Orbigny travelled on a mission for the Paris Museum, in South America between 1826 and 1833. He visited Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, Argentina, Paraguay, and Brazil, and returned to Franc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frank Chapman (ornithologist)
Frank Michler Chapman (June 12, 1864 – November 15, 1945) was an American ornithologist and pioneering writer of field guides. Biography Chapman was born in the West Englewood section of present-day Teaneck, New Jersey, and attended Englewood Academy. He joined the staff of the American Museum of Natural History in 1888 as assistant to Joel Asaph Allen. In 1901 he was made associate Curator of Mammals and Birds and in 1908 Curator of Birds. Chapman came up with the original idea for the Audubon Christmas Bird Count. He also wrote many ornithological books such as, ''Bird Life'', ''Birds of Eastern North America'', and ''Life in an Air Castle''. Chapman promoted the integration of photography into ornithology, especially in his book ''Bird Studies With a Camera'', in which he discussed the practicability of the photographic blind and in 1901 invented his own more portable version of a blind using an umbrella with a large 'skirt' to conceal the photographer that could be bund ...

Birds Of The Northern Andes
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. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, 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 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pheucticus
''Pheucticus'' is a genus of grosbeaks containing six species. The genus was introduced by the German naturalist Ludwig Reichenbach in 1850. The type species was subsequently designated as the black-backed grosbeak. Species The name of the genus is from the Ancient Greek φευκτικός - ''pheuktikós'' "shy" or "inclined to avoid".

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, 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 buildin ...

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 ...

Mixed-species Foraging Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock (birds), 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 Americas, American tropics packs of foraging golden-crowned warblers might play the same role.

Department Of Amazonas, Peru
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 ...

Nariño Department
Nariño () is a department of Colombia named after independence leader Antonio Nariño. Its capital is Pasto. It is in the west of the country, bordering Ecuador and the Pacific Ocean. Nariño has a diverse geography and varied climate according to altitude: hot in the plains of the Pacific and cold in the mountains, where most of the population resides, a situation that is repeated in a north-south direction. Other important cities include Tumaco and Ipiales. History The territory was occupied during the Pre-Columbian era by numerous Indian tribes, including Quillacingas, Awá, Pasto, and Tumas. The first European conquistador who entered the territory was Andagoya Pascual in 1522, who traveled from the Colombian Pacific coast and then used information obtained by Francisco Pizarro to organize the expedition that culminated in the conquest of Peru. Juan de Ampudia and Pedro de Añazco first explored the mountainous part of the department, commissioned by Sebastián ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
