Loxigilla Barbadensis -Barbados, Lesser Antilles, Caribbean-8
''Loxigilla'' is a genus of passerine birds in the tanager family Thraupidae. The two species are both endemic to the Lesser Antilles. Taxonomy The genus ''Loxigilla'' was introduced in 1831 by the French naturalist René Lesson. The type species was later designated as the Lesser Antillean bullfinch by George Robert Gray in 1855. The name is a combination of two genera introduced by Carl Linnaeus in 1758: ''Loxia'' for the crossbills and ''Fringilla'' for a group of finches. Although formerly placed with the buntings and New World sparrows in the family Emberizidae, molecular phylogenetic studies have shown that the genus is a member of the tanager family Thraupidae and belongs to the subfamily Coerebinae which also includes Darwin's finches. The genus contains two species, both endemic to the Lesser Antilles: The Greater Antillean bullfinch and Puerto Rican bullfinch were formerly placed in this genus, but are now placed in ''Melopyrrha ''Melopyrrha'' is a genus of passer ...

Barbados Bullfinch
The Barbados bullfinch (''Loxigilla barbadensis'') is a seedeater bird that is found only on the Caribbean island-nation of Barbados, where it is the only endemic bird species. Taxonomy The Barbados bullfinch was previously considered a subspecies of the Lesser Antillean bullfinch (''Loxigilla noctis''), which is found on neighboring islands. Despite the misleading nature of its name, the Barbados bullfinch is not a bullfinch at all but a seedeater. The bird is known locally as a Sparrow or Sparky. Description The Barbados bullfinch is a small bird, 14–15 cm (5.5–6 in). The upperparts are a dark olive-grey, the wings are mostly brown, underparts are greyish, while the under tail-coverts are tawny. The species is not sexually dimorphic, with females and males having similar plumage. The birds' calls include simple twittering, an occasional harsh petulant note, and a sharp tril Distribution and habitat The Barbados bullfinch is found only on the islan ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Endemic Birds Of The Caribbean
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Genera
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. Bi ...

Melopyrrha
''Melopyrrha'' is a genus of passerine birds in the tanager family Thraupidae. It is made up of four extant species endemic to the Greater Antilles, along with 1 possibly extinct species from the island of Saint Kitts in the Lesser Antilles. Taxonomy The genus ''Melopyrrha'' was introduced in 1853 by the French naturalist Charles Lucien Bonaparte. The type species was later specified by George Robert Gray as the Cuban bullfinch. The name combines the Ancient Greek ''melas'' meaning "black" with the genus '' Pyrrhula'' introduced by Mathurin Jacques Brisson for the bullfinches. This genus was formerly monospecific containing only the Cuban bullfinch. A molecular phylogenetic study published in 2014 found that the genus '' Loxigilla'' was polyphyletic and that the Greater Antillean bullfinch, Puerto Rican bullfinch and Cuban bullfinch formed a clade. The three species were therefore placed together in ''Melopyrrha''. In 2021, the possibly extinct St. Kitts bullfinch ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puerto Rican Bullfinch
The Puerto Rican bullfinch (''Melopyrrha portoricensis'') is a small bullfinch tanager endemic to the archipelago of Puerto Rico. The species can be commonly found in heavy forests throughout Puerto Rico, except on the easternmost tip of the island. It consumes seeds, fruits, insects, and spiders. The nest is spherical, with an entrance on the side. Typically three light green eggs are laid. Description The Puerto Rican bullfinch has black feathers with orange areas above the eyes, around its throat, and underneath the tail's base. The species measures from 17 to 19 cm and weighs approximately 32 grams. Taxonomy The presumably extinct St. Kitts bullfinch (''M. grandis''), endemic to St. Kitts, was formerly considered a subspecies. Diet Bullfinches are considered to be mainly frugivorous (and appear to prefer fruit when available) but they also consume other plant and animal material. Even though the diet of the nestling bullfinches is unknown, most frugivorous bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Antillean Bullfinch
The Greater Antillean bullfinch (''Melopyrrha violacea'') is a species of bird in the family Thraupidae. Distribution and habitat It is found in the Bahamas, Hispaniola (the Dominican Republic and Haiti, as well as surrounding islands), Jamaica, and the Turks and Caicos Islands. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, subtropical or tropical dry shrubland, and heavily degraded former forest. Taxonomy The Greater Antillean bullfinch was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Loxia violacea''. The specific epithet ''violacea'' is from Latin ''violaceus'' meaning "violet-coloured". Linnaeus based his description on "The Purple Gross-beak" that had been described and illustrated by Mark Catesby in 1731. The type locality is the Bahamas. This species was forme ...

Darwin's Finches
Darwin's finches (also known as the Galápagos finches) are a group of about 18 species of passerine birds. They are well known for their remarkable diversity in beak form and function. They are often classified as the subfamily Geospizinae or tribe Geospizini. They belong to the tanager family and are not closely related to the true finches. The closest known relative of the Galápagos finches is the South American '' Tiaris obscurus''. They were first collected when the second voyage of the ''Beagle'' visited the Galápagos Islands, with Charles Darwin on board as a gentleman naturalist. Apart from the Cocos finch, which is from Cocos Island, the others are found only on the Galápagos Islands. The term "Darwin's finches" was first applied by Percy Lowe in 1936, and popularised in 1947 by David Lack in his book ''Darwin's Finches''. Lack based his analysis on the large collection of museum specimens collected by the 1905–06 Galápagos expedition of the California Academy ...
