Jürgen Haffer
Jürgen Haffer (9 December 1932 in Berlin – 26 April 2010 in Essen) was a German ornithologist, biogeographer, and geologist. He is most remembered for his theory of Amazonian forest refugia during the Pleistocene that would have contributed to speciation and the diversification of the biota. Biography At the age of 13 Haffer found a dead bird with a ring and had taken it to the Berlin Museum where he met Erwin Stresemann who took time to explain to him the purpose of ringing. This made a big impression on him and it marked the beginning of his ornithological interest. He was the fourth child of Oskar Haffer and Margarete. His father was a high school teacher with a training in biology who encouraged an interest in natural history. After schooling, Haffer worked during the summer of 1951 under Stresemann before going to university. Knowing that ornithology did not offer a career, he studied geology and paleontology. He obtained a Diploma in 1956 and continued on for a doctor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amazon Biome
The Amazon biome ( pt, Bioma Amazônia) contains the Amazon rainforest, an area of tropical rainforest, and other ecoregions that cover most of the Amazon basin and some adjacent areas to the north and east. The biome contains blackwater and whitewater flooded forest, lowland and montane terra firma forest, bamboo and palm forest, savanna, sandy heath and alpine tundra. Some areas are threatened by deforestation for timber and to make way for pasture or soybean plantations. Location The Amazon biome has an area of . The biome roughly corresponds to the Amazon basin, but excludes areas of the Andes to the west and cerrado (savannah) to the south, and includes lands to the northeast extending to the Atlantic ocean with similar vegetation to the Amazon basin. J. J. Morrone (2006) defines the Amazonian subregion in this broader sense, divided into the biogeographical provinces of Guyana, Humid Guyana, Napo, Imeri, Roraima, Amapá, Várzea, Ucayali, Madeira, Tapajós-Xingu, Pará, Yun ...

Campina Jay
The Campina jay (''Cyanocorax hafferi'') is a passerine from the genus ''Cyanocorax'', a group of jays which occur in the Neotropics. It was first discovered in August 2002 by Mario Cohn-Haft but stayed unrecognised for two and a half years until the holotype was collected in January 2005. In 2013, this species was formally described in the Handbook of the Birds of the World. The species' epithet commemorates Dr. Jürgen Haffer, an ornithologist from Germany, best known for his Pleistocene refugia hypothesis developed in 1969. The common name '' campina'' refers to its specific habitat, a cerrado-like open savanna in the Amazon River basin in Brazil. The HBW and Birdlife checklist recognizes campina jay as a separate species. The other three taxonomic authorities - Howard & Moore, EBird/Clements and the IOC The International Olympic Committee (IOC; french: link=no, Comité international olympique, ''CIO'') is a non-governmental sports organisation based in Lausanne, ...

William Brewster (ornithologist)
William Brewster (July 5, 1851 – July 11, 1919) was an American ornithologist. He co-founded the American Ornithologists' Union (AOU) and was an early naturalist and conservationist. Early life and education Childhood William Brewster was born on July 5, 1851, in South Reading (now Wakefield), Massachusetts, the youngest of four children born to John Brewster, a successful Boston banker, and Rebecca Parker (Noyes). The couple settled in Cambridge, Massachusetts in 1845. Brewster's sister and older brothers died in early childhood, inspiring Longfellow, a close neighbor, to write the poem ''The Open Window''. Brewster attended Cambridge public schools, Washington Grammar School and Cambridge High School, taking a preparatory course to enter Harvard. He suffered eyesight problems as a youth and into adulthood. He was often unable to read or study, sometimes for extended periods. During his last year of high school, he was unable to read so his mother read his lessons t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned spec ...

Selenidera
''Selenidera'' is a bird genus containing six species of dichromatic toucanets in the toucan family Ramphastidae. They are found in lowland rainforest (below ) in tropical South America with one species in Central America. All the species have green upper-parts, red undertail-coverts and a patch of bare blue or blue-green skin around the eye. Unlike most other toucans, the sexes are different in colour (sexually dichromatic; hence the name dichromatic toucanets). The males all have a black crown, nape, throat and breast and an orange/yellow auricular streak. The females of most species have the black sections in the male replaced by rich brown and a reduced/absent auricular streak, while the female of one species, the Guianan toucanet, has grey underparts and a rufous nuchal collar, and the female of another, the yellow-eared toucanet, resemble the male except for its brown crown and lack of an auricular streak. The calls are low-pitched and croaking. Most species are relatively s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toucanet
Toucans (, ) are members of the Neotropical near passerine bird family Ramphastidae. The Ramphastidae are most closely related to the American barbets. They are brightly marked and have large, often colorful bills. The family includes five genera and over forty different species. Toucans are arboreal and typically lay 2–4 white eggs in their nests. They make their nests in tree hollows and holes excavated by other animals such as woodpeckers—the toucan bill has very limited use as an excavation tool. When the eggs hatch, the young emerge completely naked, without any down. Toucans are resident breeders and do not migrate. Toucans are usually found in pairs or small flocks. They sometimes fence with their bills and wrestle, which scientists hypothesize they do to establish dominance hierarchies. In Africa and Asia, hornbills occupy the toucans' ecological niche, an example of convergent evolution. Taxonomy and systematics The name of this bird group is derived from the ...

Neotropical
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
