Woodward's eagle (''Buteogallus woodwardi'') is an extinct species of black hawk that lived in North America and the Caribbean during the Late Pleistocene. Remains have been found in the La Brea Tar Pits in the United States and in Cuba. Despite the common name, the species is technically a gigantic variety of hawk as it is a member of the still extant black hawk genus, Buteogallus, within the Buteoninae subfamily that are chiefly referred to as hawks, and not the Aquilinae subfamily most eagles belong to. Description and ecology It is one of the largest birds of prey ever found, with an estimated total length , slightly larger than the Harpy eagle. Haast's eagle Haast's eagle (''Hieraaetus moorei'') is an Extinction, extinct species of eagle that lived in the South Island of New Zealand, commonly accepted to be the of Māori mythology.

Upper Pleistocene
The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between 129,000 and c. 11,700 years ago. The late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (commonly known as the Middle Pleistocene). The beginning of the Late Pleistocene is the transition between the end of the Penultimate Glacial Period and the beginning of the Last Interglacial around 130,000 years ago (corresponding with the beginning of Marine Isotope Stage 5). The Late Pleistocene ends with the termination of the Younger Dryas, some 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a provisional or "quasi-formal" designation by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Brea Tar Pits
La Brea Tar Pits comprise an active Paleontological site, paleontological research site in urban Los Angeles. Hancock Park was formed around a group of tar pits where natural Bitumen, asphalt (also called asphaltum, bitumen, or pitch; ''brea'' in Spanish) has seeped up from the ground for tens of thousands of years. Over many centuries, the bones of trapped animals have been preserved. The George C. Page Museum is dedicated to researching the tar pits and displaying specimens from the animals that died there. "La Brea Tar Pits" is a registered National Natural Landmark. Formation Tar pits are composed of Heavy crude oil, heavy oil fractions, called gilsonite, which seep from the earth as oil. Crude oil seeps up along the 6th Street Fault from the Salt Lake Oil Field, which underlies much of the Fairfax District north of Hancock Park. The oil reaches the surface and forms pools, becoming asphalt as the lighter fractions of the petroleum biodegrade or evaporate. The asphalt the ...

Buteogallus
''Buteogallus'' is a genus of birds of prey in the family Accipitridae. All members of this genus are essentially neotropical, but the distribution of a single species extends slightly into the extreme southwestern United States. Many of the species are fond of large crustaceans and even patrol long stretches of shore or riverbank on foot where such prey abounds, but some have a rather different lifestyle. Unlike many other genera of raptor, some members are referred to as "hawks", and others as "eagles". Most of the species have a characteristic tail pattern. This consists of a black base, a wide white middle band, a wide black band, and a quite narrow white band on the feathertips that is often hard to discern or may be lost when the feathers are very worn. Only the white-necked hawk and the rufous crab hawk have a very different tail patterns (see also below). Taxonomy The genus ''Buteogallus'' was introduced in 1830 by the French naturalist René Lesson to accommodate the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buteoninae
The Buteoninae are a subfamily of birds of prey which consists of medium to large, broad-winged species. They have large, powerful, hooked beaks for tearing flesh from their prey, strong legs, and powerful talons. They also have extremely keen eyesight to enable them to spot potential prey from a distance. This subfamily contains the buzzards (buteonine hawks) with great diversity in appearance and form and some appearing eagle-like, with at least 50 species included overall in the subfamily. At one time, several types were grouped, including large assemblages such as booted eagles, but modern studies using mitochondrial DNA clarified that this subfamily was smaller than formerly classified. Systematics The subfamily Buteoninae was introduced (as "Buteonina") by the Irish zoologist Nicholas Vigors in 1825 with '' Buteo'' as the type genus. The subfamily includes about 79 currently recognized species. Unlike the many lineages of Accipitridae which seem to have radiated out ...

Aquilinae
The Aquilinae are a subfamily of eagles of the family Accipitridae. The general common name used for members of this subfamily is "booted eagle", although this is also the common name of a member of the subfamily.Lerner, H., Christidis, L., Gamauf, A., Griffiths, C., Haring, E., Huddleston, C. J., Kabra, S., Kocum, A., Krosby, M., Kvaloy, K., Mindell, D., Rasmussen, P., Rov, N., Wadleigh, R., Michael Wink & Gjershaug, J. O. (2017). ''Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)''. ''Zootaxa'' 4216 (4), 301-320. At one point, this subfamily was considered inclusive with the Buteoninae (commonly known as buzzards or buteonine hawks) based probably on some shared morphological characteristics.Amadon, D. (1982). ''The genera of booted eagles: Aquila and relatives''. Journal of the Yamashina Institute for Ornithology, 14(2-3), 108-121. However, research on the DNA of the booted eagles has shown that they are a monophyletic group that probably have had mil ...

Harpy Eagle
The harpy eagle (''Harpia harpyja'') is a large Neotropical realm, neotropical species of eagle. It is also called the American harpy eagle to distinguish it from the Papuan eagle, which is sometimes known as the New Guinea Harpy Eagle, New Guinea harpy eagle or Papuan harpy eagle. It is the largest bird of prey throughout its range, and among the largest Extant taxon, extant species of eagles in the world. It usually inhabits tropical lowland rainforests in the upper (emergent) canopy (biology), canopy layer. Destruction of its natural habitat has caused it to vanish from many parts of its former range, and it is nearly extirpated from much of Central America. The genus ''Harpia'', together with ''Harpyopsis'', ''Macheiramphus'' and ''Morphnus'', form the subfamily Harpiinae. Taxonomy The harpy eagle was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae, 10th edition of ''Systema Naturae'' as ''Vultur harpyja'', after the mythological beast ha ...

Museum of New Zealand: Te Papa Tongarewa. Retrieved 27 October 2010. It is the largest eagle known to have existed, with an estimated weight of , compared to the next-largest and extant harpy eagle (''Harpia harpyja''), at up to . Its massive size is explained as an evolutionary response to the size of its prey—the flightless moa—the largest of which could weigh . Haast's eagle became extinct around 1445, following the Māori history#Settlement of New Zealand, arrival of the Māori, who hunted moa to extincti ...

Pleistocene Birds Of North America
The Pleistocene ( ; referred to colloquially as the ''Ice Age'') is the geological epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold glacial periods and warmer interglacials, with the sea levels being up to lower than ...
