Osbert Salvin
Osbert Salvin (25 February 1835 – 1 June 1898) was an English natural history, naturalist, Ornithology, ornithologist, and Herpetology, herpetologist best known for co-authoring ''Biologia Centrali-Americana'' (1879–1915) with Frederick DuCane Godman. This was a 52-volume encyclopedia on the natural history of Central America. Biography Osbert Salvin was born in Finchley, north London, the second son of the architect Anthony Salvin, of Hawksfold, Sussex. He was educated at Westminster School and Trinity Hall, Cambridge, taking his degree in 1857. Shortly afterwards he accompanied his second cousin by marriage, Henry Baker Tristram, in a natural history exploration of Tunisia and eastern Algeria. Their account of this trip was published in ''Ibis (journal), The Ibis'' in 1859 and 1860. In the autumn of 1857, he made the first of several visits to Guatemala, returning there with Frederick DuCane Godman in 1861. It was during this journey that the ''Biologia Centrali-Americana ...

Birds Described In 1876
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ...

Pseudastur
''Pseudastur'' is a genus of bird of prey in the family Accipitridae. It contains the following species: Systematics The name ''Pseudastur'' was coined by Edward Blyth, but was first published in George Robert Gray George Robert Gray (8 July 1808 – 6 May 1872) was an English zoology, zoologist and author, and head of the Ornithology, ornithological section of the British Museum, now the Natural History Museum, London, Natural History Museum, London f ...'s Index. The type species is the white hawk, ''Falco albicollis'' Latham, 1790. The species were placed for some time in the genus '' Leucopternis'', however this genus was found to be polyphyletic. In 2012 the American Ornithologists' Union split Leucopternis, placing the white hawk and its relatives under the old name ''Pseudastur''.

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, 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 buildin ...

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has regenerated through largely natural processes after human-caused Disturbance (ecology), disturbances, such as Logging, timber harvest or agriculture clearing, or equivalently disruptive natural phenomena. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early Seral community, 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 Ecological succession, regrowing after natural Disturbance (ecology), disturbances such as Wildfire, fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. Secondary forests are notably different from primary forests in their composition and biodiversity; however, they may still be hel ...

Cloudforest
A cloud forest, also called a water forest, primas forest, or tropical montane cloud forest, is a generally tropical or subtropical, evergreen, montane, moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level, formally described in the ''International Cloud Atlas'' (2017) as silvagenitus. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the saddles of mountains, where moisture introduced by settling clouds is more effectively retained. Cloud forests are among the most biodiversity-rich ecosystems in the world, with a large number of species directly or indirectly depending on them. Other moss forests include black spruce/ feathermoss climax forest, with a moderately dense canopy and a forest floor of feathermosses, including '' Hylocomium splendens'', '' Pleurozium schreberi'', and '' Pt ...

Semi-deciduous
Semi-deciduous or semi-evergreen is a botanical term which refers to plants that lose their foliage for a very short period, when old leaves fall off and new foliage growth is starting. This phenomenon occurs in tropical and sub-tropical woody species, for example in '' Dipteryx odorata''. Semi-deciduous or semi-evergreen may also describe some trees, bushes or plants that normally only lose part of their foliage in autumn/winter or during the dry season, but might lose all their leaves in a manner similar to deciduous In the fields of horticulture and botany, the term deciduous () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed Leaf, leaves, usually in the autumn; to the shedding of petals, aft ... trees in an especially cold autumn/winter or severe dry season (drought).

Department Of Tumbes
Tumbes () is a coastal department and region in northwestern Peru bordering Ecuador. Due to the region's location near the Equator it has a warm climate, with beaches that are considered among the finest in Peru. Despite its small area, the region contains a wide variety of ecosystems. It is the smallest department in Peru and its third least populous department after Moquegua and Madre de Dios, but it is also its third most densely populated department, after La Libertad and Lambayeque. The name "Tumbes" originates from either ''Tumpis'', a group of native peoples from the area, the word ''tumbos'', a species of Passiflora that used to abound in the area, or the name of the Tumba cacique, whose son founded and populated the area. Geography The Tumbes Region is bordered by the Ecuadorian provinces of El Oro and Loja on the east; Peru's Piura Region on the south; and by the Pacific Ocean on the north and west. Morphologically, four zones can be defined in the region: t ...

Endangered Species (IUCN Status)
Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second-most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively. IUCN Red List The IUCN Red List is a list of species which have been assessed according to a system of assigning a global conservation status. According to the latest system used by the IUCN, a species can be "Data Deficient" (DD) species – species for which more data and assessment is required before their situation may be determined – as well species comprehensively assessed by the IUCN's species assessment process. A species can be " ...
