Black-crowned Tanager
The black-crowned tanager or black-crowned palm-tanager (''Phaenicophilus palmarum'') is a species of bird of the family Phaenicophilidae, the Hispaniolan tanagers. It is endemic to the island of Hispaniola which is shared by Haiti and the Dominican Republic. Taxonomy and systematics In 1760, the French zoologist Mathurin Jacques Brisson included a description of the black-crowned tanager in his ''Ornithologie''. He used the French name ''Le palmiste'' and the Latin name ''Merula palmarum''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Although Brisson coined Latin names, these do not conform to the binomial system, and are not recognised by the International Commission on Zoological Nomenclature. When the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the twelfth edition in 1766, he added 240 species that had been previously described by Brisson; one of them was the black-c ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey-crowned Tanager

Hispaniolan Moist Forests
The Hispaniolan moist forests are a tropical moist broadleaf forest ecoregion on the island of Hispaniola. They cover , around 60% of the island's area. Geography Moist forests occur on most of the eastern half the Dominican Republic, stretching from the coast all the way to high elevations in the mountains. In Haiti, they are found in the Tiburon Peninsula in the southern part of the country as well as the Massif du Nord. The drainage basins for the island's main rivers, the Yaque del Norte and Yaque del Sur, Yuna, and Artibonite, occur in this ecoregion. The forests cover diverse topography, including flatlands, valleys, plateaus, slopes and foothills up to an altitude of about . Soils are either calcareous (neutral or somewhat alkaline) or acidic. Climate Mesic forests receive of annual rainfall, while more than falls in wet forests. The rainy season lasts from April to December.

Hispaniolan Dry Forests
The Hispaniolan dry forests are a tropical dry broadleaf forest ecoregion on the island of Hispaniola (split between the Dominican Republic and Haiti). They cover , around 20% of the island's area. Geography The dry forests are found mostly on the southern and western portions of the island of Hispaniola, covering portions of both the Dominican Republic and Haiti. The ecoregion covers the southern and western coastal lowlands, the Cul-de-Sac–Enriquillo lowland, and the Cibao Valley in the north-central portion of the island. Flora Plant communities include high dry forest and cactus scrub dominated by species of ''Prosopis, Pilosocereus, Hippomane, Cylindropuntia, Agave'', and ''Bursera'', as well as '' Melocactus lemairei''.Cano-Ortiz, Ana & Musarella, Carmelo & Piñar Fuentes, José Carlos & Gomes, Carlos & Cano, Eusébio.

Tiburon Peninsula
The Tiburon Peninsula (french: Péninsule de Tiburon), or The Xaragua Peninsula, simply "the Tiburon" (''le Tiburon''), is a region of Haiti encompassing most of Haiti's southern coast. It starts roughly at the southernmost point of the Haiti-Dominican Republic border and extends westward near Cuba, forming a large headland. Three of Haiti's ten departments are located entirely within the region. They are the departments of Grand'Anse, Nippes and Sud. Etymology The wordTiburonand Xaragua are linked to the Taino natives who were the region's first inhabitants. The region is often referred to as the Great South, le Grand-Sud (french), or Nansid (Haitian). Administrative Division The Tiburon is 1 of the 4 regions of Haiti, administrated through 4 departments and 1 arrondissement. Half of Sud-Est is also located within the Tiburon Peninsula. A large part of Ouest department is also located in the region, with the capital, Port-au-Prince serving as the line of demarcation betw ...

Saona Island
Saona Island ( es, Isla Saona) is a 110 square kilometer tropical island located off the south-east coast in Dominican Republic's La Altagracia province. It is a government-protected nature reserve and is part of '' Parque Nacional Cotubanamá''. There are two permanent settlements, the towns of ''Mano Juan'' and ''Catuano.'' Mano Juan is a fishing village with wooden houses and "Catuano beach" has a detachment of the navy. The island is a popular destination for tourists from all over the Dominican Republic, who arrive in fleets of catamarans and small motorboats on organized excursions every day. It is known for its beaches, and has been used on a number of occasions by filmmakers and advertisers looking for a stereotypical "deserted island" setting for their film or product. Such notable films include Pirates of the Caribbean (2003), and The Blue Lagoon.

Covert Feather
A covert feather or tectrix on a bird is one of a set of feathers, called coverts (or ''tectrices''), which, as the name implies, cover other feathers. The coverts help to smooth airflow over the wings and tail. Ear coverts The ear coverts are small feathers behind the bird's eye which cover the ear opening (the ear of a bird has no external features) Tail coverts The uppertail and undertail coverts cover the base of the tail feathers above and below. Sometimes these coverts are more specialised. The "tail" of a peacock is made of very elongated uppertail coverts. Wing coverts The upperwing coverts fall into two groups: those on the inner wing, which overlay the secondary flight feathers, known as the secondary coverts, and those on the outerwing, which overlay the primary flight feathers, the primary coverts. Within each group, the feathers form a number of rows. The feathers of the outermost, largest, row are termed greater (primary-/secondary-) coverts; those in the next row ...

Mandible
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower tooth, teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed prenatal development, in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from ''wikt:mandere ...

Maxilla
The maxilla (plural: ''maxillae'' ) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw. Structure In humans, the maxilla consists of: * The body of the maxilla * Four processes ** the zygomatic process ** the frontal process of maxilla ** the alveolar process ** the palatine process * three surfaces – anterior, posterior, medial * the Infraorbital foramen * the maxillary sinus * the incisive foramen Articulations Each maxilla articulates with nine bones: * two of the cranium: the frontal and ethmoid * seven of the face: the nasal, zygomatic, lacrimal, inferior n ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...
