Grayish Piculet
The greyish piculet (''Picumnus granadensis'') is a species of bird in subfamily Picumninae of the woodpecker family Picidae. It is endemic to Colombia. Taxonomy and systematics The greyish piculet has two described subspecies, the nominate ''P. g. granadensis'' and ''P. g. antioquensis'' (Chapman, 1915). The greyish piculet and the olivaceous piculet (''P. olivaceus'') were at one time considered to be conspecific and are now treated as sister species. However, the "evidence for treatment as separate species is weak".Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D. F. Lane, J. F. Pacheco, M. B. Robbins, F. G.

Frédéric De Lafresnaye
Baron Nöel Frédéric Armand André de Lafresnaye (24 July 1783 – 14 July 1861) was a French ornithologist and collector. Lafresnaye was born into an aristocratic family at Chateau de La Fresnaye in Falaise, Calvados, Falaise, Normandy. He took an early interest in natural history, particularly entomology. It was only after acquiring a collection of European birds that he turned his attention to ornithology. Lafresnaye described a number of new bird species, some with Alcide d'Orbigny. He accumulated a collection of over 8,000 bird skins at his home. After his death the collection was purchased by the American collector Henry Bryant (naturalist), Henry Bryant and donated to the Boston Society of Natural History, Boston Natural History Society. It was transferred to the Museum of Comparative Zoology in 1914. Lafresnaye's piculet, Lafresnaye's woodcreeper and Lafresnaye's vanga are avian species that bear his name.

Birds Of The Colombian Andes
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. Bird ...

Picumnus (bird)
''Picumnus'' is a large genus of piculets. With a total length of 8–10 cm (3–4 in), they are among the smallest birds in the woodpecker family. Species limits in this genus are doubtful, and the rate of interbreeding is "inordinately high" (Remsen et al. 2007). As defined by Winkler and Christie (2002), it contains the 27 species listed below, all from the Neotropics except the speckled piculet, which is Asian (and sometimes placed in a monotypic genus, ''Vivia''). Their upperparts are brownish, greyish or olive, in some species with darker barring or white or yellowish spotting on the mantle. The underparts vary greatly among the species, ranging from all rich brown in the chestnut piculet, to whitish in the plain-breasted piculet, white with dark bars in the white-barred piculet, and pale yellowish with dark bars on the chest and dark spots and streaks on the belly in the bar-breasted piculet. They have black crowns with red, orange, or yellow marks in the male ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Olivaceous Piculet
The olivaceous piculet (''Picumnus olivaceus'') is a species of bird in subfamily Picumninae of the woodpecker family Picidae. It is found from Guatemala south through Central America and western South America to Peru. Taxonomy and systematics The olivaceous piculet has these six subspecies: *''P. o. dimotus'' Bangs, 1903 *''P. o. flavotinctus'' Ridgway, 1889 *''P. o. olivaceus'' Lafresnaye, 1845 *''P. o. eisenmanni'' Phelps, W.H.

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.

Primary Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patía River
The Patía River () is a river in southwestern Colombia. It flows over to drain into the Pacific Ocean north of Tumaco. The Patía River is the longest river on the Colombian Pacific Coast. The last is navigable by boat. Geography The Patía River begins in the Department of Cauca south of the city of Popayán near the town of Timbío. The source of the river begins in the gap between the West Andes and Central Andes very near the source of the Cauca River. The Patía river flows westward from the Central massif of Colombia, cuts through the Western Cordillera and drains into the Pacific Ocean. In its upper section it runs through cloud forests and montane forests. The central section of the river flows through the Patía Valley dry forests ecoregion. The lower section to the west of the Western Cordillera flows through the Chocó jungles of the Pacific region. The Patía is fed by the Quilcacé, Guachicono, Mayo, Juanambú, Pasto and Guaitara rivers.
