Spinus Xanthogastrus
The yellow-bellied siskin (''Spinus xanthogastrus'') is a small passerine bird in the finch family Fringillidae. It breeds from Costa Rica south to southern Ecuador, central Bolivia and the highlands of northwestern Venezuela. The yellow-bellied siskin breeds in mountain oak forests at altitudes between 800–3,000 m. The nest is a shallow cup of rootlets, bark and lichens 2.4–3.7 m high in the dense foliage of a small tree in a clearing. The two or three green-tinged white eggs are laid in April or May and incubated by the female. Although not migratory, this species wanders within its range when not breeding. The yellow-bellied siskin is a small bird, 10.5 cm in length and weighing 12 g. The male is entirely black except for a bright yellow belly, tail sides and wing patches. The female is dark olive green above and has pale yellow underparts which become brighter on the belly. She has a blackish tail and wings and also has bright yellow primary win ...

Bernard Du Bus De Gisignies
Bernard Amé Léonard du Bus de Gisignies (21 June 1808 in Saint-Josse-ten-Noode – 6 July 1874 in Bad Ems) was a Dutch nobleman and later on a Belgium, Belgian politician, ornithologist and paleontologist. He was the second son of Leonard Pierre Joseph du Bus de Gisignies. He married ''Petronilla Truyts'' on 19 May 1845, together they had two children; Viscount Bernard Daniel (Saint-Josse-ten-Noode, 7 October 1832 - City of Brussels, Brussels, 17 February 1917) and Viscount Chretien (Saint-Josse-ten-Noode, 4 November 1845 - Jabbeke, 3 July 1883). He studied law at the State University of Louvain, but soon became more interested in ornithology. In 1835 he presented a manuscript to the The Royal Academies for Science and the Arts of Belgium, Royal Academy of Belgium in which described the bird ''Leptorhynchus pectoralis'' (the banded stilt). He was a member of parliament for Soignies. He became the first director of the Royal Belgian Institute of Natural Sciences in 1846. On ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Panama
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 ...

This is a list of the bird species recorded in Venezuela. The avifauna of Venezuela has 1402 confirmed species, of which 45 are endemic, six have been introduced by humans, 35 are rare or vagrants Vagrancy is the condition of homelessness without regular employment or income. Vagrants (also known as bums, vagabonds, rogues, tramps or drifters) usually live in poverty and support themselves by begging, scavenging, petty theft, temporar ..., and one has been local extinction, extirpated. An additional 21 species are hypothetical (see below).

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 ...

Lesser Goldfinch
The lesser goldfinch (''Spinus psaltria'') is a very small songbird of the Americas. Together with its relatives the American goldfinch and Lawrence's goldfinch, it forms the New World goldfinch clade in the genus '' Spinus''. As is the case for all three New World goldfinches (and some of their siskin relatives), lesser goldfinch males have a black forehead, which females lack. Males in this species vary strikingly in back color across their range, from green in western North America to black from Texas south to South America. Five subspecies are often recognized. Taxonomy The lesser goldfinch was formally described by the American zoologist Thomas Say in 1822 under the binomial name ''Fringilla psaltria''. The specific epithet ''psaltria'' is Ancient Greek for a female harpist. The type locality is Colorado Springs, Colorado. The lesser goldfinch is now placed in the genus '' Spinus'' that was introduced in 1816 by the German naturalist Carl Ludwig Koch. Five subspecies are ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passeri ...
