Buteogallus Daggetti
''Buteogallus daggetti'', occasionally called "Daggett's eagle" or the "walking eagle", is an extinct species of long-legged hawk which lived in southwest North America during the Pleistocene. Initially believed to be some sort of carrion-eating eagle, it was for some time placed in the distinct genus ''Wetmoregyps'', named for Alexander Wetmore. It probably resembled a larger version of the modern-day savanna hawk, with its long legs possibly used like the secretarybird of Africa to hunt for small reptiles from a safe distance. It died out about 13,000 years ago. Fossils of ''B. daggetti'' were discovered in the La Brea and Carpinteria lagerstätte in southern California, and in Nuevo León in Mexico. Its habitat included grasslands, marshlands, brushy savannas and ponds. It probably ate mostly small reptiles such as snakes. As is often the case with birds of prey, the female seems to have been larger than the male. Description In life, ''B. daggetti'' is thought to have r ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 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 grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

San Diego Zoo Global
San Diego Zoo Wildlife Alliance is a nonprofit organization, not-for-profit organization headquartered in San Diego that operates the San Diego Zoo and the San Diego Zoo Safari Park. Founded in 1916 as the Zoological Society of San Diego under the leadership of Harry M. Wegeforth, the organization claims the largest zoological society membership in the world, with more than 250,000 member households and 130,000 child memberships, representing more than half a million people. The organization's mission is to save species worldwide by uniting their expertise in animal care and conservation science with their dedication to inspiring passion for nature. In its first few decades, the Zoological Society of San Diego worked to establish and build up the San Diego Zoo. Members of the organization formed groups that later became the Association of Zoos and Aquariums (AZA) and American Association of Zoo Keepers. In the early 1970s the society established the San Diego Wild Animal Park in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great Black Hawk
The great black hawk (''Buteogallus urubitinga'') is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and Old World vultures. Taxonomy The great black hawk was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the eagles, hawks and relatives in the genus '' Falco'' and coined the binomial name ''Falco urubitinga''. Gmelin's description was ultimately based on the "urubitinga" that had been described in 1648 by the German naturalist Georg Marcgrave in his '' Historia Naturalis Brasiliae''. The great black hawk is now one of nine species placed in the genus '' Buteogallus'' was introduced in 1830 by the French naturalist René Lesson. The name genus is a portmanteau of ''Buteo'', a genus introduced in 1779 by Bernard Germain de Lacépède for the buzzards and the genus '' Gallus'' introduced in 1760 by Mathurin Jacques Brisson for ...

Caracara (genus)
''Caracara'' is a genus in the family Falconidae and the subfamily Polyborinae. It contains one extant species, the crested caracara; and one extinct species, the Guadalupe caracara. The South American Classification Committee of the American Ornithological Society has voted to again merge the two, retaining ''C. plancus'' as crested caracara. The taxonomists of the International Ornithologists' Union have also merged them. Appearance The crested caracara is distinguished by its long legs and medium size. The birds can reach a length of from head to tail. There are usually four points of identification of the caracara: strikingly white markings on the neck, the tip of both wings, and the tail. Along with their medium length, the caracara also has a wingspan of . When flying, the caracara is often noted to have a pattern on their underside that looks like a cross. Behavior The behaviors of caracaras are considered quite strange in relation to those of other falcons. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodward's Eagle
Woodward's eagle (''Buteogallus woodwardi'') is an extinct species of eagle that lived in North America and the Caribbean during the Late Pleistocene. 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 extinct species of eagle that once lived in the South Island of New Zealand, commonly accepted to be the pouakai of Māori legend. Woodward's eagle appears to have hunted in open habitats, taking primarily small mammals and reptiles. References Ple ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalanges
The phalanges (singular: ''phalanx'' ) are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones. Structure The phalanges are the bones that make up the fingers of the hand and the toes of the foot. There are 56 phalanges in the human body, with fourteen on each hand and foot. Three phalanges are present on each finger and toe, with the exception of the thumb and large toe, which possess only two. The middle and far phalanges of the fifth toes are often fused together (symphalangism). The phalanges of the hand are commonly known as the finger bones. The phalanges of the foot differ from the hand in that they are often shorter and more compressed, especially in the proximal phalanges, those closest to the torso. A phalanx is named according to whether it is proximal, middle, or distal and its associated finger or toe. The proxim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coracoid
A coracoid (from Greek κόραξ, ''koraks'', raven) is a paired bone which is part of the shoulder assembly in all vertebrates except therian mammals (marsupials and placentals). In therian mammals (including humans), a coracoid process is present as part of the scapula, but this is not homologous with the coracoid bone of most other vertebrates. In other tetrapods it joins the scapula to the front end of the sternum and has a notch on the dorsal surface which, along with a similar notch on the ventral surface of the scapula, forms the socket in which the proximal end of the humerus (upper arm bone) is located. The acrocoracoid process is an expansion adjacent to this contact surface, to which the shoulderward end of the biceps brachii muscle attaches in these animals. In birds (and generally theropods and related animals), the entire unit is rigid and called scapulocoracoid. This plays a major role in bird flight. In dinosaurs the main bones of the pectoral girdle were the sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tibiotarsus
The tibiotarsus is the large bone between the femur and the tarsometatarsus in the leg of a bird. It is the fusion of the proximal part of the tarsus with the tibia. A similar structure also occurred in the Mesozoic Heterodontosauridae. These small ornithischian dinosaurs were unrelated to birds and the similarity of their foot bones is best explained by convergent evolution. See also *Bird anatomy References * Proctor, Nobel S.
