Black-and-chestnut Eagle
The black-and-chestnut eagle (''Spizaetus isidori'') is a South American species of bird of prey in the family Accipitridae. It is sometimes called Isidor's eagle. It is often placed in the monotypic genus ''Oroaetus''. However, recent genetic testing indicates that this species is fairly closely related to ''Spizaetus'' species and thus the species should be included in that genus.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., Wink, M. & Gjershaug, J.O. (2017). ''Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)''. Zootaxa, 4216(4), 301–320. Description This is a fairly large eagle and very large raptor at in total length with a wingspan of . It is largest current member of the genus ''Spizaetus'', with the smallest males somewhat larger than the largest female ornate hawk-eagles.Bierregaard, R. O., G. M. Kirwan, ...

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.

Snake
Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, altho ...

Guan (bird)
The guans are a number of bird genera which make up the largest group in the family Cracidae. They are found mainly in northern South America, southern Central America, and a few adjacent Caribbean islands. There is also the peculiar horned guan (''Oreophasis derbianus'') which is not a true guan, but a very distinct and ancient cracid with no close living relatives (Pereira ''et al.'' 2002). Systematics and evolution The evolution of the group is fairly well resolved due to comprehensive analyses of morphology, biogeography, and mt and nDNA sequences (Pereira ''et al.'' 2002, Grau ''et al.'' 2005). The position of ''Penelopina'' and ''Chamaepetes'' - peculiar genera of which the former, uniquely among guans and more in line with curassows, shows pronounced sexual dimorphism - relative to each other is not determinable with certainty at present, but all evidence suggests that they are the basalmost guans. Their distribution is fairly far northwards, with 2 of their 3 species li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coati
Coatis, also known as coatimundis (), are members of the family Procyonidae in the genera ''Nasua'' and ''Nasuella''. They are diurnal mammals native to South America, Central America, Mexico, and the southwestern United States. The name "coatimundi" comes from the Tupian languages of Brazil, where it means "lone coati". Locally in Belize, the coati is known as "quash". Physical characteristics Adult coatis measure from head to the base of the tail, which can be as long as their bodies. Coatis are about tall at the shoulder and weigh between , about the size of a large house cat. Males can become almost twice as large as females and have large, sharp canine teeth. The measurements above relate to the white-nosed and South America coatis. The two mountain coatis are smaller. All coatis share a slender head with an elongated, flexible, slightly upward-turned nose, small ears, dark feet, and a long, non-prehensile tail used for balance and signaling. Ring-tailed coatis have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porcupine
Porcupines are large rodents with coats of sharp spines, or quills, that protect them against predation. The term covers two families of animals: the Old World porcupines of family Hystricidae, and the New World porcupines of family, Erethizontidae. Both families belong to the infraorder Hystricognathi within the profoundly diverse order Rodentia and display superficially similar coats of rigid or semi-rigid quills, which are modified hairs composed of keratin. Despite this, the two groups are distinct from one another and are not closely related to each other within the Hystricognathi. The largest species of porcupine is the third-largest living rodent in the world, after the capybara and beaver. The Old World porcupines (Hystricidae) live in Italy, Asia (western and southern), and most of Africa. They are large, terrestrial, and strictly nocturnal. The New World porcupines (Erethizontidae) are indigenous to North America and northern South America. They live in wooded area ...

Capuchin Monkey
The capuchin monkeys () are New World monkeys of the subfamily Cebinae. They are readily identified as the " organ grinder" monkey, and have been used in many movies and television shows. The range of capuchin monkeys includes some tropical forests in Central America and South America as far south as northern Argentina. In Central America, where they are called white-faced monkeys ("carablanca"), they usually occupy the wet lowland forests on the Caribbean coast of Costa Rica and Panama and deciduous dry forest on the Pacific coast. Etymology The word "capuchin" derives from a group of friars named the Order of Friars Minor Capuchin, an offshoot from the Franciscans, who wear brown robes with large hoods. When Portuguese explorers reached the Americas in the 15th century, they found small monkeys whose coloring resembled these friars, especially when in their robes with hoods down, and named them capuchins. When the scientists described a specimen (thought to be a golden-bel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woolly Monkey
The woolly monkeys are the genus ''Lagothrix'' of New World monkeys, usually placed in the family Atelidae. Both species in this genus originate from the rainforests of South America. They have prehensile tails and live in relatively large social groups. Taxonomy The following 2 species and 5 subspecies are currently considered to be within the genus: *Yellow-tailed woolly monkey, ''L. flavicauda'' (formerly placed in genus ''Oreonax'') * Common woolly monkey, ''L. lagothricha'' ** Gray woolly monkey, ''L. l. cana'' **Brown woolly monkey, ''L. l. lagothricha'' ** Colombian woolly monkey, ''L. l. lugens'' ** Silvery woolly monkey, ''L. l. poeppigii'' ** Peruvian woolly monkey, ''L. l. tschudii'' Description Woolly monkeys are closely related to spider monkeys. They have a thick brown coat with dark gray appendages. The stomach area is black and heads are light brown. The fur color is the same for both males and females. Variation in color exist among subspecies. A prehensile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...

Squirrel
Squirrels are members of the family Sciuridae, a family that includes small or medium-size rodents. The squirrel family includes tree squirrels, ground squirrels (including chipmunks and prairie dogs, among others), and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and to the dormice. Etymology The word ''squirrel'', first attested in 1327, comes from the Anglo-Norman which is from the Old French , the reflex of a Latin word , which was taken from the Ancient Greek word (; from ) 'shadow-tailed', referring to the long bushy tail which many of its members have. The native Old English word for the squirrel, , survived only into Middle English (as ) before being replaced. The Old English word is of Common Germanic origin, cognat ...

Cloud Forest
A cloud forest, also called a water forest, primas forest, or tropical montane cloud forest (TMCF), is a generally tropical or subtropical, evergreen, montane, moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level, formally described in the ''International Cloud Atlas'' (2017) as silvagenitus. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the saddles of mountains, where moisture introduced by settling clouds is more effectively retained. Cloud forests are among the most biodiversity rich ecosystems in the world with a large amount of species directly or indirectly depending on them. Other moss forests include black spruce/feathermoss climax forest, with a moderately dense canopy and a forest floor of feathermosses including ''Hylocomium splendens'', ''Pleurozium schreberi'' and ''Ptil ...
