Rufous-shafted Woodstar
The rufous-shafted woodstar (''Chaetocercus jourdanii'') is a species of hummingbird in tribe Mellisugini of subfamily Trochilinae, the "bee hummingbirds". It is found in Colombia, Trinidad and Tobago, and Venezuela. Taxonomy and systematics The rufous-shafted woodstar was formally described in 1839 by the French ornithologist Jules Bourcier based on specimens collected in Trinidad. Bourcier placed the new species in the genus ''Ornismya'' and coined the binomial name ''Ornismya jourdanii''. The species is now placed in the genus ''Chaetocercus'' that was introduced in 1855 by the English zoologist George Robert Gray with the rufous-shafted woodstar as the type species. The genus name is a combination of the Ancient Greek words ''khaitē'', meaning "hair" and ''kerkos'', meaning "tail". The specific epithet was chosen by Bourcier to honour the French zoologist Claude Jourdan. Three subspecies are recognised: * ''C. j. andinus'' Phelps, WH & Phelps, WH Jr, 1949 – northea ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vagrancy (biology)
Vagrancy is a phenomenon in biology whereby an individual animal (usually a bird) appears well outside its normal range (biology), range; they are known as vagrants. The term accidental is sometimes also used. There are a number of poorly understood factors which might cause an animal to become a vagrant, including internal causes such as navigatory errors (endogenous vagrancy) and external causes such as severe weather (exogenous vagrancy). Vagrancy events may lead to colonisation and eventually to speciation. Birds In the Northern Hemisphere, adult birds (possibly inexperienced younger adults) of many species are known to continue past their normal breeding range during their spring migration and end up in areas further north (such birds are termed spring overshoots). In autumn, some young birds, instead of heading to their usual wintering grounds, take "incorrect" courses and migrate through areas which are not on their normal migration path. For example, Siberian passeri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Ornithological Society
The American Ornithological Society (AOS) is an ornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. Its members are primarily professional ornithologists, although membership is open to anyone with an interest in birds. The society publishes the two scholarly journals, ''The Auk'' and '' The Condor'' as well as the ''AOS Checklist of North American Birds''. In 2013, the American Ornithologists' Union announced a close partnership with the Cooper Ornithological Society, including joint meetings, a centralized publishing office, and a refocusing of their respective journals to increase efficiency of research. In October 2016, the AOU announced that it was ceasing to operate as an independent union and was merging with the Cooper Ornithological Society to create the American Ornithological Society.
