Red Warbler
The red warbler (''Cardellina rubra'') is a small passerine bird of the New World warbler family Parulidae endemic to the highlands of Mexico, north of the Isthmus of Tehuantepec. It is closely related to, and forms a superspecies with, the pink-headed warbler of southern Mexico and Guatemala. There are three subspecies, found in disjunct populations, which differ in the color of their ear patch and in the brightness and tone of their body plumage. The adult is bright red, with a white or gray ear patch, depending on the subspecies; young birds are pinkish-brown, with a whitish ear patch and two pale . Breeding typically occurs between February and May. The female lays three or four eggs in a domed nest, which she builds on the ground. Though she alone incubates the eggs, both sexes feed the young and remove fecal sacs from the nest. The young fledge within 10–11 days of hatching. The red warbler is an insectivore, gleaning primarily in understory shrubs. Although this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gleaning (birds)
Gleaning is a feeding strategy by birds and bats in which they catch invertebrate prey, mainly arthropods, by plucking them from foliage or the ground, from crevices such as rock faces and under the eaves of houses, or even, as in the case of ticks and lice, from living animals. This behavior is contrasted with Hawking (birds), hawking insects from the air or chasing after moving insects such as ants. Gleaning, in birds, does not refer to foraging for seeds or fruit. Gleaning is a common feeding strategy for some groups of birds, including nuthatches, Tit (bird), tits (including chickadees), wrens, Ovenbird (family), woodcreepers, treecreepers, Old World flycatchers, Tyrant flycatchers, Old World babbler, babblers, Old World warblers, New World warblers, Vireos and some hummingbirds and cuckoos. Many birds make use of multiple feeding strategies, depending on the availability of different sources of food and opportunities of the moment. Techniques and adaptations Foliage glea ...

Old World
The "Old World" () is a term for Afro-Eurasia coined by Europeans after 1493, when they became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia in the Eastern Hemisphere, previously thought of by the Europeans as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas. Etymology In the context of archaeology and world history, the term "Old World" includes those parts of the world which were in (indirect) cultural contact from the Bronze Age onwards, resulting in the parallel development of the early civilizations, mostly in the temperate zone between roughly the 45th and 25th parallels north, in the area of the Mediterranean, including North Africa. It also included Mesopotamia, the Persian plateau, the Indian subcontinent, China, and parts of Sub-Saharan Africa. These regions were connected via the Silk Road trade route, and ...

Basileuterus
''Basileuterus'' is a genus of New World warblers, best represented in Central and South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern Subregion#Americas, subregion o .... This is one of only two warbler genera that are well represented in the latter continent. Some species formerly considered in this genus are now placed in the genus '' Myiothlypis''. It is likely that the ancestors of this genus colonised South America from the family's heartland in northern Central America even before the two continents were linked, and subsequent speciation provided most of the resident warbler species of that region. These are mainly robust warblers with a stout bill. The majority of species have olive or grey upperparts and yellow underparts. The head is often strikingly marked with a long broad supercilium, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-faced Warbler
The red-faced warbler (''Cardellina rubrifrons'') is a species of New World warbler. Mature red-faced warblers are small birds, long. They are light gray on top with a white rump and a white underside. The face, neck, and upper breast are all bright red, while the crown and sides of the head are black. The spot on the back of the head where the black crown and gray back meet is sometimes speckled gray, or sometimes plain white. They have a quirky habit of flicking their tail sideways while feeding. Red-faced warblers are locally common in mountain forests of conifers and oak at above sea level. In summer they frequent northern Mexico and range up into the states of Arizona and New Mexico – the Madrean sky islands. In winter they migrate south into southern Mexico and the Central American nations of El Salvador, Guatemala, and Honduras. They are permanent residents of the central and southern mountains of western Mexico, the range called Sierra Madre Occidental. The nest ...

Cardellina
''Cardellina'' is a genus of passerine birds in the New World warbler family Parulidae. The genus name ''Cardellina'' is a diminutive of the Italian dialect word ''Cardella'' for the European goldfinch. Taxonomy The genus was introduced by the French naturalist Charles Lucien Bonaparte in 1850. The type species was subsequently designated as the red-faced warbler. The genus originally contained one species, the red-faced warbler. A comprehensive study of the wood-warblers published in 2010 that analysed mitochondrial and nuclear DNA sequences found that the five species formed a discrete clade, with the Wilson's and Canada warblers as early offshoots, followed by a lineage that gave rise to two branches – one leading to the red-faced and another that diverged to the red and pink-headed warblers. Spencer Fullerton Baird described the genus ''Ergaticus'' in 1865, using it to separate several species from what he felt was the closely related genus ''Cardellina'', and eventually ...

Setophaga
''Setophaga'' is a genus of birds of the New World warbler family Parulidae. It contains at least 34 species. The ''Setophaga'' warblers are an example of adaptive radiation with the various species using different feeding techniques and often feeding in different parts of the same tree. Most ''Setophaga'' species are long-range migrants, wintering in or near the New World tropics and seasonally migrating to breed in North America. In contrast, two ''Setophaga'' species, the palm warbler and yellow-rumped warbler, have winter ranges that extend along the Atlantic coast of North America as far north as Nova Scotia. The males in breeding plumage are often highly colorful. Etymology The genus name ''Setophaga'' means ''moth eater'' in Ancient Greek; from : ''sēs'' (genitive σητός : ''sētós''), "moth", and : ''phágos'', "eating". Taxonomy The genus ''Setophaga'' was introduced by the English naturalist William Swainson in 1827. The type species was subsequently designat ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mexican War Of Independence
The Mexican War of Independence (, 16 September 1810 – 27 September 1821) was an armed conflict and political process resulting in Mexico's independence from the Spanish Empire. It was not a single, coherent event, but local and regional struggles that occurred within the same period, and can be considered a List of wars of independence, revolutionary civil war. It culminated with the drafting of the Declaration of Independence (Mexico), Declaration of Independence of the Mexican Empire in Mexico City on September 28, 1821, following the collapse of royal government and the military triumph of forces for independence. Mexican independence from Spain was not an inevitable outcome of the relationship between the Spanish Empire and its most valuable overseas possession, but events in Spain had a direct impact on the outbreak of the armed insurgency in 1810 and the course of warfare through the end of the conflict.

William Bullock (collector)
William Bullock ( – 7 March 1849) was an English traveller, naturalist and antiquarian. He established what was called Bullock's Museum, first in Liverpool which he then moved to London. Life Bullock began as a goldsmith and jeweller in Birmingham. By 1795, Bullock was in Liverpool, where he founded a Museum of Natural Curiosities at 24 Lord Street. While still trading as a jeweller and goldsmith, in 1801, he published a descriptive catalogue of the works of art, armoury, objects of natural history, and other curiosities in the collection, some of which had been brought back by members of James Cook's expeditions. In 1809, Bullock moved to London and the collection, housed first at 22 Piccadilly and in 1812 in the newly built Piccadilly Egyptian Hall, proved extremely popular. The collection, which included over 32,000 items, was disposed of by auction in 1819. In 1810, Bullock figured briefly in a law case concerning Sarah Baartman, a Khoikhoi woman brought to England for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Habitat Destruction
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as the ...
