(Molothrus Bonariensis) E ( Zonotrichia Capensis )
Cowbirds are birds belonging to the genus ''Molothrus'' in the family Icteridae. They are of New World origin, and are obligate brood parasites, laying their eggs in the nests of other species. The genus was introduced by English naturalist William John Swainson in 1832 with the brown-headed cowbird (''Molothrus ater'') as the type species. The genus name combines the Ancient Greek , meaning "struggle" or "battle", with , meaning "to sire" or "to impregnate". Species The genus contains six species: One extinct species, the Talara cowbird (''Molothrus resinosus''), is known from fossil remains recovered from the Talara Tar Seeps of northwestern Peru, and likely went extinct during the late Quaternary. It may have been a close associate of Pleistocene megafauna communities, and may have gone extinct following their collapse in populations. The nonparasitic baywings were formerly placed in this genus; they are now classified as ''Agelaioides''. Behavior Cowbirds are insec ...

William John Swainson
William John Swainson FLS, FRS (8 October 1789 – 6 December 1855), was an English ornithologist, malacologist, conchologist, entomologist and artist. Life Swainson was born in Dover Place, St Mary Newington, London, the eldest son of John Timothy Swainson the Second (1756–1824), an original fellow of the Linnean Society. He was cousin of the amateur botanist Isaac Swainson.Etymologisches Worterbuch der botanischen Pflanzennamen by H. Genaust. Review by Paul A. Fryxell ''Taxon'', Vol. 38(2), 245–246 (1989). His father's family originated in Lancashire, and both grandfather and father held high posts in Her Majesty's Customs, the father becoming Collector at Liverpool. William, whose formal education was curtailed because of an impediment in his speech, joined the Liverpool Customs as a junior clerk at the age of 14."William Swainson F.R.S, F.L.S., Naturalist and Artist: Diaries 1808–1838: Sicily, Malta, Greece, Italy and Brazil."

Screaming Cowbird (Molothrus Rufoaxillaris)
The screaming cowbird (''Molothrus rufoaxillaris'') is an obligate brood parasite belonging to the family Icteridae and is found in South America. It is also known commonly as the short billed cowbird.Fraga, R. M. (2011). Family Icteridae (New World Blackbirds). In Handbook of the Birds of the World, vol 16: Tanagers to New World Blackbirds (J. del Hoyo,. A. Elliot, and D. A. Christie, Editors). Lynx Edicions, Barcelona, Spain. pp. 684-807 Description The screaming cowbird has mildly iridescent black plumage; the lesser under-wing coverts are rufous. The female is slightly duller in colour than the male. The legs are black and the iris is reddish brown. Adult body length is 18–21 cm and mean adult weight is 58 g for males and 48 g for females.Davies, N. B. (2000). Cuckoos, Cowbirds and Other Cheats. Academic Press, London The call of the screaming cowbird was first described as "impetuous screaming notes"; however, a more useful description for field identificat ...

Insectivores
A robber fly eating a hoverfly An insectivore is a carnivorous animal or plant that eats insects. An alternative term is entomophage, which can also refer to the human practice of eating insects. The first vertebrate insectivores were amphibians. When they evolved 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects is an extension of piscivory. At one time, insectivorous mammals were scientifically classified in an order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related. Most of the Insectivora taxa have been reclassified; those that have not yet been reclassified and found to be truly related to each other remain in the order Eulipotyphla. Although individually small, insects exist in enormous numbers. Insects make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baywing
The baywings are two species of birds in the genus ''Agelaioides'', which were described in the early 19th century. These species are found in Brazil and in the case of ''A. badius'', also Argentina, Bolivia, Uruguay, and Paraguay Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America.

Pleistocene Megafauna
Pleistocene megafauna is the set of large animals that lived on Earth during the Pleistocene epoch. Pleistocene megafauna became extinct during the Quaternary extinction event resulting in substantial changes to ecosystems globally. The role of humans in causing Pleistocene megafaunal extinctions is controversial. Megafauna are any animals with an adult body weight of over . Pleistocene megafauna include the straight-tusked elephant, cave bear (''Ursus spelaeus''), interglacial rhinoceros (''Stephanorhinus''), heavy-bodied Asian antelope ('' Spirocerus''), Eurasian hippopotamuses, woolly rhinoceros, mammoths, giant deer, sabre-toothed cat (''Homotherium''), cave lion, and the leopard in Europe. Paleoecology The last glacial period, commonly referred to as the 'Ice Age', spanned 125,000 to 14,500 years ago and was the most recent glacial period within the current ice age which occurred during the final years of the Pleistocene epoch. The Ice Age reached its peak during the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Quaternary
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global sign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Talara Tar Seeps
Talara is a city in the Talara Province of the Piura Region, in northwestern Peru. It is a port city on the Pacific Ocean with a population of 91,444 as of 2017. Its climate is hot and dry. Due to its oil reserves, and ability to produce aviation fuel, Talara hosted a United States air base during World War II. It was also one of two refueling stations for the Pacific Fleet. There were naval guns on the hills, and submarine nets in the harbor. The Ajax, Achilles and Exeter, three British destroyers, were refuelled there on their way around the Horn to catch the Graf Spee in Rio de la Plata. Talara is also home to a large fishing fleet. The city is served by the Cap. FAP Víctor Montes Arias Airport. Talara is the westernmost city in all of mainland South America. (A small outlying town, Seccion Dieciocho, is situated slightly further west, and just beyond there, the land itself reaches its westernmost extent at Punta Pariñas.)

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
