Grey-headed Dove
The grey-headed dove (''Leptotila plumbeiceps'') is a large New World dove. It is found from eastern Mexico to Colombia. Taxonomy and systematics The grey-headed dove, the grey-fronted dove (''Leptotila rufaxilla'') and pallid dove (''L. pallida'') of South America, the Azuero dove (''L. battyi'') of Central America, and the Grenada dove (''L. wellsi'') of Grenada were at one time thought to be a single species. Grey-headed dove, grey-fronted dove, and pallid dove are possibly a superspecies.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D. F. Lane, J. F. Pacheco, M. B.

Philip Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an England, English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River (Wisconsin–Minnesota), St. Croix River, cano ...

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 speci ...

Birds Described In 1868
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 swimming. Birds ...

Leptotila
''Leptotila'' is a genus of birds in the dove and pigeon family Columbidae. These are ground-foraging doves that live in the Americas. The genus ''Leptotila'' was introduced by the English naturalist William John Swainson in 1837 with the Caribbean dove ''Leptotila jamaicensis'' as the type species. The genus name combines the Ancient Greek ''leptos'' meaning "delicate" or "slender" with meaning "feather". The genus contains the following 11 species: * White-tipped dove, ''Leptotila verreauxi'' * Yungas dove, ''Leptotila megalura'' * Grey-fronted dove, ''Leptotila rufaxilla'' * Grey-headed dove, ''Leptotila plumbeiceps'' * Pallid dove, ''Leptotila pallida'' * Azuero dove, ''Leptotila battyi'' – split from the grey-headed dove * Grenada dove, ''Leptotila wellsi'' * Caribbean dove, ''Leptotila jamaicensis'' * Grey-chested dove, ''Leptotila cassinii'' * Ochre-bellied dove, ''Leptotila ochraceiventris'' * Tolima dove, ''Leptotila conoveri'' Cladogram showing the position ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenology
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonality, seasonal and interannual variations in climate, as well as environmental factor, habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of bird migration, migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies. In the scientific literature on ecology, the term is used more generally to indicate the time frame for any seasonal biological phenomena, including the dates of last appearance (e.g., the seasonal phenology of a species may be from April through September). Because many such phenomena are very sensitive to small variations in climate, especially to temperature, phenological records can be a useful proxy (climate), proxy for ...

Puracé
Puracé is an andesitic stratovolcano located in the Puracé National Natural Park in the Cauca Department, Colombia. It is part of the North Volcanic Zone of the Andean Volcanic Belt. The volcano is located at the intersection of the Coconucos and Morras Faults.Plancha 365, 2003 It is one of the most active volcanoes in Colombia. Large explosive eruptions occurred in 1849, 1869, 1885, 1949, 1950, 1956, and 1957. There were about a dozen eruptions in the 20th century, the most recent being in 1977. On this occasion, volcanic ash was deposited away. Fumaroles were seen near the summit in 1990, and hot springs emerged from some of the lower slopes. __TOC__ Panorama See also * List of volcanoes in Colombia * List of volcanoes by elevation A list (incomplete) of volcanoes on Earth arranged by elevation in metres. 6,000 metres 5,000 metres 4,000 metres 3,000 metres 2,000 metres 1,000 metres Below 1,000 metres From its base on the ocean flo ...

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. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Clements Taxonomy
''The Clements Checklist of Birds of the World'' is a book by Jim Clements which presents a list of the bird species of the world. The most recent printed version is the sixth edition (2007), but has been updated yearly, the last version in 2022, and is published by Cornell University Press. Previous editions were published by the author's own imprint, Ibis Publishing. The Cornell Lab of Ornithology has provided annual updates since then, usually in August, and the most recent version is available online in several formats. These updates reflect the ongoing changes to bird taxonomy based on published research. ''Clements'' is the official list used by the American Birding Association for birds globally. eBird eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance. Originally restricted to sightings from the Western Hemisphere, the project ... also uses the ''Clem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
