Rose-throated Tanager
The rose-throated tanager (''Piranga roseogularis'') is a medium-sized songbird in the family Cardinalidae, the cardinals or cardinal grosbeaks. Endemic to the Yucatán Peninsula in Central America, it is found in Belize, Guatemala, and Mexico.Hilty, S. (2020). Rose-throated Tanager (''Piranga roseogularis''), version 1.0.

Taxonomy and systematics American ornithologist Samuel Cabot III described the rose-throated tanager in 1846, having seen a pair in the Yucatán Peninsula and shooting the male. A 2019 genetic study using mitochondrial DNA showed that it was a basal (early offshoot) of a lineage that gave rise to the scarlet, hepatic, summer, w ...

Samuel Cabot III
Samuel Cabot III (September 20, 1815 – April 13, 1885) was an American physician, surgeon, and ornithologist, as well as a member of the wealthy and prominent Cabot family. Early life Samuel Cabot III was born in Boston, Massachusetts on September 20, 1815 to Samuel Cabot, Jr. and Elizabeth Cabot (née Perkins). His father, Samuel Cabot, Jr. and his grandfather, Thomas Handasyd Perkins, were two of the wealthiest men in 19th-century Boston. Among his brothers were the lawyer, philosopher, and author James Elliot Cabot and the architect and artist Edward Clarke Cabot.Briggs, L. Vernon''History and Genealogy of the Cabot Family'' Boston: C. E. Goodspeed, 1927, vol. 2, pp. 685–686. Cabot attended Boston Latin School as a child, and received a B.A. from Harvard University in 1836, followed by an M.D. from Harvard Medical School in 1839. Medical career After receiving his medical degree, Cabot went to Paris for further studies, returning to Boston in July 1841. In the winter o ...

Yucatán Peninsula
The Yucatán Peninsula (, also , ; es, Península de Yucatán ) is a large peninsula in southeastern Mexico and adjacent portions of Belize and Guatemala. The peninsula extends towards the northeast, separating the Gulf of Mexico to the north and west of the peninsula from the Caribbean Sea to the east. The Yucatán Channel, between the northeastern corner of the peninsula and Cuba, connects the two bodies of water. The peninsula is approximately in area. It has low relief, and is almost entirely composed of porous limestone. The peninsula lies east of the Isthmus of Tehuantepec, the narrowest point in Mexico separating the Atlantic Ocean, including the Gulf of Mexico and Caribbean Sea, from the Pacific Ocean. Some consider the isthmus to be the geographic boundary between Central America and the rest of North America, placing the peninsula in Central America. Politically all of Mexico, including the Yucatán, is generally considered part of North America, while Guatemala an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Belize
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. Birds ...

Piranga
''Piranga'' is a genus of birds long placed in the tanager family, but now considered members of the cardinal family, Cardinalidae. The genus name ''Piranga'' is from Tupi word ''tijepiranga'', the name for an unknown small bird. Similar in shape and habits to the true tanagers, their coloration betrays their actual relationships. They are essentially red, orange, or yellow all over, except the tail and wings, and in some species also the back. Such extensive lipochrome coloration (except on the belly) is very rare in true tanagers, but is widespread among the Cardinalidae. These songbirds are found high in tree canopies, and are not very gregarious in their breeding areas. ''Piranga'' species pick insects from leaves, or sometimes in flight. They also take some fruit. Several species are migratory, breeding in North America and wintering in the tropics. Taxonomy and species list The genus ''Piranga'' was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1 ...

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] |
Phenology
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonality, seasonal and interannual variations in climate, as well as environmental factor, habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of bird migration, 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 (climate), proxy for ...

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 ...

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 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.

Cozumel
Cozumel (; yua, Kùutsmil) is an island and municipality in the Caribbean Sea off the eastern coast of Mexico's Yucatán Peninsula, opposite Playa del Carmen. It is separated from the mainland by the Cozumel Channel and is close to the Yucatán Channel. The municipality is part of the state of Quintana Roo, Mexico. The economy of Cozumel is based on tourism, with visitors able to benefit from the island's balnearios, scuba diving, and snorkeling. The main town on the island is San Miguel de Cozumel. Etymology The name ''Cozumel'' was derived from the Mayan "Cuzamil" or "Ah Cuzamil Peten" in full, which means "the island of swallows" ( es, link=no, Isla de las Golondrinas). Geography The island is located in the Caribbean Sea along the eastern side of the Yucatan Peninsula about south of Cancún and from the mainland. The island is about long and wide. With a total area of , it is Mexico's largest Caribbean island, largest permanently inhabited island, and Mexico's third ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isla Mujeres
Isla Mujeres (, Spanish language, Spanish for "Women Island" (formally “Isla de Mujeres”) is an island where the Gulf of Mexico and the Caribbean Sea meet, about off the Yucatán Peninsula coast in the State of Quintana Roo, Mexico. It is approximately long and wide. To the east is the Caribbean Sea with a strong Ocean surface wave, surf and rock (geology), rocky coast, and to the west the skyline of Cancún can be seen across the waters. In the 2010 census, the namesake town on the island had a population of 12,642 inhabitants. The town is the seat of Isla Mujeres (municipality), Isla Mujeres Municipality. Very little violent crime has been reported on the island over its history, leading the island to gain a reputation for its relaxed nature, with the safety of both residents and tourists being unusually high. The biggest danger to the residents of the island has historically been the threat of tropical storms and hurricanes, some of which have caused devastating damage, ...

Thraupidae
The tanagers (singular ) comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds. Traditionally, the family contained around 240 species of mostly brightly colored fruit-eating birds. As more of these birds were studied using modern molecular techniques, it became apparent that the traditional families were not monophyletic. ''Euphonia'' and ''Chlorophonia'', which were once considered part of the tanager family, are now treated as members of the Fringillidae, in their own subfamily (Euphoniinae). Likewise, the genera ''Piranga'' (which includes the scarlet tanager, summer tanager, and western tanager), '' Chlorothraupis'', and '' Habia'' appear to be members of the cardinal family, and have been reassigned to that family by the American Ornithological Society.
