John Dennis (ornithologist)
John Value Dennis (1915/1916 – December 1, 2002) was an American ornithologist and botanist. Dennis was an undergraduate at George Washington University but his study was interrupted by World War II. During the war, he served as a radar technician with the Flying Tigers aircraft unit in China. He finished his undergraduate education at the University of Wisconsin, obtaining a degree in political science. This was followed by a master's degree in botany from the University of Florida. He started (but did not complete) a PhD in ornithology at the University of Illinois. He studied woodpeckers in particular and searched extensively for the critically endangered ivory-billed woodpecker in Cuba and in old-growth forests of the southeastern United States. In 1948, working with Davis Crompton, he traveled to the Oriente Province of Cuba and located a subspecies, called the Cuban ivory-billed woodpecker, after it had not been reported there for several years. He reported a sighti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campephilus Principalis Bairdii
The Cuban ivory-billed woodpecker ( es, carpintero real, link=no) (''Campephilus principalis bairdii'') is a subspecies of the ivory-billed woodpecker native to Cuba. Originally classified as a separate species, recent research has indicated that ''C. p. bairdii'' may, in fact, be sufficiently distinct from the nominate subspecies to once again be regarded as a species in its own right. There have been no confirmed sightings of the bird since 1987; it is generally believed to be extinct, although the survival of some individuals is considered a remote possibility. Taxonomy and appearance ''C. p. bairdii'' was originally designated as a separate species (''C. bairdii'') by John Cassin, based on suggestions by Spencer Fullerton Baird. Cassin described it as: Much resembling '' C. principalis'', but smaller and with the black anterior feathers of the crest longer than those succeeding, which are scarlet. White longitudinal line on the neck reaching quite to the base of the bil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Princess Anne, Maryland
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Bird Feeding
Bird feeding is the activity of feeding wild birds, often by means of bird feeders. With a recorded history dating to the 6th century, the feeding of wild birds has been encouraged and celebrated in the United States and United Kingdom, with it being the United States' second most popular hobby having National Bird-Feeding Month congressionally decreed in 1994. Various types of food are provided by various methods; certain combinations of food and method of feeding are known to attract certain bird species. The feeding of wild birds has been shown to have possible negative as well as positive effects; while a study in Sheffield, England found that the abundance of garden birds increased with levels of bird feeding, multiple reports suggest that bird feeding may have various negative ecological effects and may be detrimental to the birds being fed, including increased risk of predatory action and malnutrition. It has been estimated that American adults spend approximately US$3.8 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big Thicket National Preserve
The Big Thicket is the name given to a somewhat imprecise region of a heavily-forested area of Southeast Texas in the United States. This area represents a portion of the mixed pine-hardwood forests of southeast US. The National Park Service established the Big Thicket National Preserve (BTNP) within the region in 1974 and it is recognized as a biosphere reserve by UNESCO. Although the diversity of animals in the area is high, with over 500 vertebrates, it is the complex mosaic of ecosystems and plant diversity that is particularly remarkable. Biologists have identified at least eight, and up to eleven, ecosystems in the Big Thicket area. More than 160 species of trees and shrubs, 800 herbs and vines, and 340 types of grasses are known to occur in the Big Thicket, and estimates as high as over 1000 flowering plant species and 200 trees and shrubs have been made, plus ferns, carnivorous plants, and more. The Big Thicket has historically been the most dense forest region in what is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oriente Province
Oriente (, "East") was the easternmost province of Cuba until 1976. The term "Oriente" is still used to refer to the eastern part of the country, which currently is divided into five different provinces. Fidel and Raúl Castro were born in a small town in this province (Birán). The origins of Oriente lie in the 1607 division of Cuba into a western and eastern administration. The eastern part was governed from Santiago de Cuba and it was subordinate to the national government in Havana. In 1807, Cuba was divided into three ''departamentos'': Occidental, Central and Oriental. This arrangement lasted until 1851, when the central department was merged back into the West. In 1878, Cuba was divided into six provinces. Oriente remained intact but was officially renamed to Santiago de Cuba Province until the name was reverted to Oriente in 1905. This lasted until 1976, when the province was split into five different provinces: Las Tunas Province, Granma Province, Holguín Province, San ...

Ornithologist
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists who i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
