Stripe-cheeked Woodpecker (Piculus Callopterus) 2
The stripe-cheeked woodpecker (''Piculus callopterus'') is a species of bird in subfamily Picinae of the woodpecker family Picidae. It is endemic to Panama. Taxonomy and systematics The stripe-cheeked woodpecker was originally described as ''Chloronerpes callopterus''. Since its inclusion in ''Piculus'' it has at times been considered conspecific with the rufous-winged woodpecker (''P. simplex''), the white-throated woodpecker (''P. leucolaemus''), and the Lita woodpecker (''P. litae''); the four may form a superspecies.Winkler, H., D.

George Newbold Lawrence
George Newbold Lawrence (October 20, 1806 – January 17, 1895) was an American businessman and amateur ornithologist. Early life Lawrence was born in the city of New York on October 20, 1806. From his youth, Lawrence was a lover of birds and spent much of his spare time studying their habits. At sixteen years of age, he became a clerk in his father's business, becoming a partner in his father's house by age twenty. Career Lawrence conducted Pacific bird surveys for Spencer Fullerton Baird and John Cassin, and the three men co-authored ''Birds of North America'' in 1860. He sold his collection of 8,000 bird skins to the American Museum of Natural History in 1887. Fellow ornithologists honored him by naming one bird genus and 20 species after him, including both the scientific and common name of the Lawrence's goldfinch Lawrence's goldfinch (''Spinus lawrencei'') is a small songbird of erratic distribution that breeds in California and Baja California and winters in the ...

Mandible
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from '' mandere'' "to chew" and ''-bula'' ...

Birds Of Panama
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piculus
''Piculus'' is a genus of birds in the woodpecker family Picidae that are found in Central and South America. Taxonomy The genus was introduced by the German naturalist Johann Baptist von Spix in 1824. The type species was subsequently designated as the golden-green woodpecker (''Piculus chrysochloros'') by the American ornithologist Harry C. Oberholser in 1923. The generic name is a diminutive of the Latin word ''Picus'' meaning "woodpecker". The genus forms part of the woodpecker subfamily Picinae and has a sister relationship to the genus ''Dryocopus'' whose species are found in Eurasia and the Americas. The genus ''Piculus'' is a member of the tribe Picini and belongs to a clade that contains five genera: ''Colaptes'', ''Piculus'', '' Mulleripicus'', ''Dryocopus'' and ''Celeus''. The genus contains seven species: Five other species, formerly placed here, are now in ''Colaptes ''Colaptes'' is a genus of birds in the woodpecker family Picidae. The 14 species are found ...

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] |
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.

American Ornithological Society
The American Ornithological Society (AOS) is an ornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. Its members are primarily professional ornithologists, although membership is open to anyone with an interest in birds. The society publishes the two scholarly journals, '' The Auk'' and '' The Condor'' as well as the '' AOS Checklist of North American Birds''. In 2013, the American Ornithologists' Union announced a close partnership with the Cooper Ornithological Society, including joint meetings, a centralized publishing office, and a refocusing of their respective journals to increase efficiency of research. In October 2016, the AOU announced that it was ceasing to operate as an independent union and was merging with the Cooper Ornithological Society to create the American Ornithological Society.

Darién Province
Darién (, , ) is a province in Panama whose capital city is La Palma. With an area of , it is located at the eastern end of the country and bordered to the north by the province of Panamá and the region of Kuna Yala. To the south, it is bordered by the Pacific Ocean and Colombia. To the east, it borders Colombia; to the west, it borders the Pacific Ocean and the province of Panama. The area surrounding the border with Colombia is known as the Darién Gap, a large swath of undeveloped swampland and forest. With no roads, it is the missing link of the Pan-American Highway. Place names The name originates from the language spoken by the Cueva, an Indigenous tribe destroyed by the white European conquistadors during the 16th century. The Tanela River, which flows toward Atrato, was Hispanicized to Darién; the region and its communities took the same name. Santa María la Antigua del Darién, the first city founded in Tierra Firme, also took its name from the river. Subseque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veraguas Province
Veraguas () is a province of Panama, located in the centre-west of the country. The capital is the city of Santiago de Veraguas. It is the only Panamanian province to border both the Atlantic and Pacific oceans. It covers an area of 10,587.6 km² and in 2019 it had an estimated population of 247,644. History Veraguas was originally inhabited by the Veraguas culture. Veraguas was explored by Christopher Columbus on his fourth voyage. He tried to establish the first colony in the new Spanish mainland but failed due to resistance from Indigenous peoples. Diego de Nicuesa also tried to establish a colony and failed, which made him create a colony to fight against the Indigenous population, which he named Nombre de Dios. Its capital, Santiago de Veraguas, was founded about 1636. It is said that its name comes from the indigenous word "Veracua" or "Viragua", though other theories abound. It is the only province in Panama with coastlines on both the Caribbean Sea and the Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...
