Red Siskin
The red siskin (''Spinus cucullatus'') is a small endangered finch native to tropical South America - in northern Colombia, northern Venezuela (where it is called the "cardenalito") and Guyana. It was common in the early 20th century, occurring throughout the foothills of northern Venezuela, but has now become extremely rare in a fragmented range. The population on Trinidad is believed to be extirpated, with no sightings since 1960. Habitat The red siskin is found in open country, forest edges and grassland with trees or shrubs. The female is believed to lay three greenish-white eggs in a grassy cup nest in a tree. Description The red siskin is about 10 cm long. The male is mainly deep red, with black on the head, throat, flight feathers and tail tip, and a whitish lower belly and under tail. The female is grey on the head, breast, and upper parts, apart from a red rump and upper tail. The breast is grey with reddish flanks, and the rest of the underparts, the wings and ta ...

William John Swainson
William John Swainson FLS, FRS (8 October 1789 – 6 December 1855), was an English ornithologist, malacologist, conchologist, entomologist and artist. Life Swainson was born in Dover Place, St Mary Newington, London, the eldest son of John Timothy Swainson the Second (1756–1824), an original fellow of the Linnean Society. He was cousin of the amateur botanist Isaac Swainson.Etymologisches Worterbuch der botanischen Pflanzennamen by H. Genaust. Review by Paul A. Fryxell ''Taxon'', Vol. 38(2), 245–246 (1989). His father's family originated in Lancashire, and both grandfather and father held high posts in Her Majesty's Customs, the father becoming Collector at Liverpool. William, whose formal education was curtailed because of an impediment in his speech, joined the Liverpool Customs as a junior clerk at the age of 14."William Swainson F.R.S, F.L.S., Naturalist and Artist: Diaries 1808–1838: Sicily, Malta, Greece, Italy and Brazil."

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ...

Birds Described In 1820
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 ...

Birds Of Puerto Rico
This is a list of the bird species recorded in the archipelago of Puerto Rico, which consists of the main island of Puerto Rico, two island municipalities off the east coast (Vieques and Culebra), three uninhabited islands off the west coast ( Mona, Monito and Desecheo) and more than 125 smaller cays and islands. The avifauna of Puerto Rico included a total of 385 species as of July 2022, according to ''Bird Checklists of the World''. Of them, 201 are accidental, two have been extirpated, and one is believed to be extinct. Seventeen species are endemic. Non-native species are common; 43 listed here were introduced by humans. Individuals of many other species (mostly parrots, finches, and waxbills) are flying free, presumably after escaping or being released from captivity. For example, a 2018 study on introduced Psittacidae on the island found at least 46 species present, of which 24% are only found in the pet trade (captivity), 48% have been observed in the wild (but are n ...

Birds Of Trinidad And Tobago
A total of 487 species of birds have been confirmed on the islands of Trinidad and Tobago. Of them, two are endemic, six have been introduced by humans, 130 are rare or vagrants, and 11 have been extirpated. The status of one more has not been determined. There are few places in the world where so many bird species can be seen in such a small area, many of them unique, very rare, or of particular interest. They range from the many species of hummingbird to the cave-dwelling oilbird (which uses echo-location to fly in the dark) and the scarlet ibis. The islands are within a few miles of Venezuela, and the species are therefore typical of tropical South America. However, the number of species is relatively low compared to the mainland, as would be expected on small islands. The resident breeding birds are augmented in the northern winter by migrants from North America, although the variety of migrant passerines is very limited compared to Central America. Unless otherwise n ...

Spinus (genus)
''Spinus'' is a genus of passerine birds in the finch family. It contains the North and South American siskins and goldfinches, as well as two Old World species. The genus name is from the Ancient Greek ''spínos'', a name for a now-unidentifiable bird. All of the species in the genus, except for the Tibetan serin, were formerly included in the genus ''Carduelis''. They were moved to the resurrected genus ''Spinus'' based on phylogenetic studies of mitochondrial and nuclear DNA sequences. The Tibetan serin was formerly placed in the genus ''Serinus''. The Eurasian siskin and the Tibetan serin are the only species from the Old World included in the group. The genus ''Spinus'' was introduced in 1816 by the German naturalist Carl Ludwig Koch with the Eurasian siskin (''Spinus spinus'') as the type species. Evolution and phylogeny The Tibetan serin is an outgroup within ''Spinus'', having been the first to diverge. The remainder of the genus can be divided into three monophyle ...

Smithsonian Conservation Biology Institute
The Smithsonian Conservation Biology Institute (SCBI) is a unit of the Smithsonian Institution located on a campus located just outside the town of Front Royal, Virginia. An extension of the National Zoo in Washington, D.C., the SCBI has played a leading role in the fields of veterinary medicine, reproductive physiology and conservation biology since its founding in 1974. Previously named the Conservation and Research Center, the CRC became known as the Smithsonian Conservation Biology Institute in 2010 as a symbol of its growing independence from the captive animals associated with the traditional images of zoos. History The land on which the SCBI lies has a history dating back to 1909, when the United States Army leased some 42 area farms. In the years predating World War I, the land served as a series of U.S. Army Remount Service depots, supplying horses and mules to the military. The federal government ultimately purchased the land in 1911 and began construction on the Ay ...

CITES Appendix I
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...
