Humboldt's White-fronted Capuchin
Humboldt's white-fronted capuchin (''Cebus albifrons'') is a species of gracile capuchin monkey. It is found in Colombia, Venezuela, Brazil, and potentially the island of Trinidad. Taxonomy The species name ''Cebus albifrons'' was formerly considered to also include several types of white-fronted capuchin monkey which are now regarded as separate species based on genetic studies by Boubli and Lynch Alfaro. Trinidad white-fronted capuchin Boubli ''et al''. found in a 2012 study that the Trinidad white-fronted capuchin, capuchins on Trinidad, previously classified as ''C. albifrons trinitatis'', had derived from within ''C. olivaceus brunneus'' (or more specifically, the mitochondrial genes of the single Trinidad specimen they sampled derived from ''brunneus''). However, the morphological distinctiveness of Trinidad populations has led to doubts over this taxonomy. Further complicating this taxonomy is the fact that subsequent morphological inspection of the ''C. brunneus'' spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a modern Western scientific point of view. His description of the journey was written up and published in several volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected the use ...

Gestation
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. The time interval of a gestation is called the '' gestation period''. In obstetrics, ''gestational age'' refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks. Mammals In mammals, pregnancy begins when a zygote (fertilized ovum) implants in the female's uterus and ends once the fetus leaves the uterus during labor or an abortion (whether induced or spontaneous). Humans In humans, pregnancy can be defined clinically or biochemically. Clinically, pregnancy starts from first day of the mother's last period. Biochemically, pregnancy starts when a woman's human chorionic gonadotropin (hCG) levels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harpy Eagle
The harpy eagle (''Harpia harpyja'') is a 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 or Papuan harpy eagle. It is the largest and most powerful raptor found throughout its range, and among the largest extant species of eagles in the world. It usually inhabits tropical lowland rainforests in the upper (emergent) 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. In Brazil, the harpy eagle is also known as royal-hawk (in pt, gavião-real). The genus ''Harpia'', together with '' Harpyopsis'' 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'' as ''Vultur harpyja'', after the mythological beast harpy.

Tayra
The tayra (''Eira barbara'') is an omnivorous animal from the weasel family, native to the Americas. It is the only species in the genus ''Eira''. Tayras are also known as the ''tolomuco'' or ''perico ligero'' in Central America, ''motete'' in Honduras, ''irara'' in Brazil, ''san hol'' or ''viejo de monte'' in the Yucatan Peninsula, and high-woods dog (or historically ''chien bois'') in Trinidad. The genus name ''Eira'' is derived from the indigenous name of the animal in Bolivia and Peru, while ''barbara'' means "strange" or "foreign". Description Tayras are long, slender animals with an appearance similar to that of weasels and martens. They range from in length, not including a 37- to 46-cm-long (15 to 18 in) bushy tail, and weigh . Males are larger, and slightly more muscular, than females. They have short, dark brown to black fur which is relatively uniform across the body, limbs, and tail, except for a yellow or orange spot on the chest. The fur on the head and neck is ...

Ornate Hawk-eagle
The ornate hawk-eagle (''Spizaetus ornatus'') is a fairly large bird of prey from the tropical Americas. Formerly, some authorities referred to this species as the crested hawk-eagle, a name that may cause some confusion as it is more commonly used for an Asian eagle species.Friedmann H. (1935). ''A new race of the Crested Hawk-eagle Spizaetus ornatus''. Journal of the Washington Academy of Sciences, 25 (10): 450-451. Like all eagles, it is in the family Accipitridae. This species has a feathered tarsus that marks it as a member of the ''Aquilinae'' or booted eagle 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., Wink, M. & Gjershaug, J.O. (2017). ''Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)''. Zootaxa, 4216(4), 301-320.

Black-and-white Hawk-eagle
The black-and-white hawk-eagle (''Spizaetus melanoleucus'', formerly ''Spizastur melanoleucus'') is a bird of prey species in the eagle and hawk family (Accipitridae). It is found throughout a large part of tropical America, from southern Mexico to northern Argentina. Description As its name suggests, this is a black and white eagle, resembling the small typical eagles sometimes separated in ''"Hieraaetus"''. It is some long overall and weighs about . The head, neck and body are white; a small crest forms a black spot on top of the head, and the area around the eyes, particularly towards the bill, is also black. The wings are black with a noticeable white leading edge, and the bird has a brownish tail barred black-dark grey and with white tip. The iris is orange in adults and greyish in juveniles, the feet pale to bright yellow with black talons. The bill is black with a yellow cere. The sexes are alike in color, but the female is larger. Immature birds have pale edges on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecuadorian Squirrel Monkey
The Ecuadorian squirrel monkey (''Saimiri cassiquiarensis macrodon'') is a type of squirrel monkey. It had been considered a subspecies of the Guianan squirrel monkey, ''Saimiri sciureus'', but was elevated to a full species, ''S. macrodon'', based on a 2009 study by Carretero-Pinzón, ''et al''. Based on subsequent genetic research by Jessica Lynch Alfaro, ''et al'' it was again reclassified as a subspecies of Humboldt's squirrel monkey. The Ecuadorian squirrel monkey lives in the western Brazilian Amazon, as well as southern Colombia, eastern Ecuador and northern and eastern Peru. It lives in humid tropical and subtropical forest, preferring dense forest but able to live in secondary forest A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. ... and disturbed forest as well.

Humboldt's Squirrel Monkey
Humboldt's squirrel monkey (''Saimiri cassiquiarensis'') is a species of squirrel monkey from Brazil, Colombia, Ecuador, Peru and Venezuela. It had previously been considered a subspecies of the common squirrel monkey, ''S. scuireus'', but was elevated to full species status based on a genetic study by Carretero-Pinzón in 2009. A genetic study by Jessica Lynch Alfaro, ''et al'' indicated that the Ecuadorian squirrel monkey may be synonymous with ''Saimiri cassiquiarensis''. As of 2018, the Ecuadorian squirrel monkey is generally regarded as a subspecies of Humboldt's squirrel monkey, ''S. cassiquiarensis macrodon''. Humboldt's squirrel monkey have a head and body length of between with a tail between . Its coloration is similar to that of the Guianan squirrel monkey but the fur on the base of the crown is golden yellow as compared with gray for the Guianan squirrel monkey. It eats fruits when available, primarily between January and June, and also eats insects. References [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venezuelan Red Howler
The Colombian red howler or Venezuelan red howler (''Alouatta seniculus'') is a South American species of howler monkey, a type of New World monkey, found in the western Amazon Basin in Venezuela, Colombia, Ecuador, Peru and Brazil. The population in the Santa Cruz Department in Bolivia was split off as a separate species, the Bolivian red howler, in 1986, and more recently, splitting off the population in northeastern South America and Trinidad as the Guyanan red howler has occurred. All howler monkeys belong to the family Atelidae and the infraorder Platyrrhini (New World monkeys). Description Sexual dimorphism in this species is small; males range from 49 to 72 cm and females from 46 to 57 cm long. The males weigh 5.4-9 kg, while females weigh 4.2–7 kg. It has a long prehensile tail of 49–75 cm. The tail is covered with fur except for the last third of the underside, which allows it to grab branches. The color of both males and females is a deep reddi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Woolly Monkey
The common woolly monkey, brown woolly monkey, or Humboldt's woolly monkey (''Lagothrix lagothricha'') is a woolly monkey from Colombia, Ecuador, Peru, Bolivia, Brazil, and Venezuela. It lives in groups of two to 70 individuals, usually splitting the group into smaller subgroups when active. Taxonomy The taxonomy of the common woolly monkey is still debated. Fooden classified it is as one of two species under the genus ''Lagothrix'' with four sub-species (''L. l. lagotricha'', ''L. l. lugens'', ''L. l. cana'', and ''L. l. poeppgigii''. Later, an analysis of craniodental morphology suggested a move of all sub-species to the species level and also led to the yellow-tailed woolly monkey (formerly ''Lagothrix flavicauda'') being moved to a monotypic genus ''Oreonax''. Genetic analyses also identify distinct groups, but different groupings from morphological and molecular data continue to make this a difficult issue that might be addressed with larger data sets.
