Oriente Warbler
The Oriente warbler (''Teretistris fornsi'') is one of two species of bird in the Cuban warbler family Teretistridae. It is endemic to central and eastern Cuba. Taxonomy and systematics The Oriente warbler shares its family and genus with the yellow-headed warbler (''T. fernandinae''). They were originally placed in the New World warblers (Parulidae) but phylogenetic studies of nuclear and mitochondrial DNA led to reassessment of several genera and in 2017 the Cuban warblers were moved to their own family. Their closest relatives are the four members of family Spindalidae, the yellow-breasted chat (''Icteria virens''), and the New World blackbirds of family Icteridae. Chesser, R. T., S. M.

Cayo Romano
Cayo Romano is an island on the northern coast of Cuba, in the province of Camagüey. It is the largest cay of the Jardines del Rey archipelago with . Overview Administratively is part of Nuevitas, but the closest municipality on Cuban Mainland are Esmeralda and Bolivia. The cay is a popular for birdwatchers but is otherwise undeveloped, compared to the intensive resort developments on nearby Cayo Coco.Sainsburg, Brendan, ''Cuba'' Lonely Planet Guide 2009, p. 247 To the south, the Bay of Jiguey separates it from the main island of Cuba. To the north it is bordered by the Old Bahama Channel and The Bahamas to 20 miles. At the northwest corner is Cayo Paredon Grande, which has an old lighthouse. Cayo Megano Grande, Cayo Cruz as well as many reefs are developed on the northern shore. Cayo Coco is located to the north-west, and Cayo Guajaba to the south-east. A road runs from Cayo Coco, across Cayo Romano to Cayo Paredon Grande. However, the bridge from Cayo Coco is not suitable ...

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 ...

Birds Described In 1858
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Cuba
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] |
Teretistris
The Cuban warblers are a genus, ''Teretistris'', and family, Teretistridae, of birds endemic to Cuba and its surrounding cays. Until 2002 they were thought to be New World warblers, but DNA studies have shown that they are not closely related to that family. The family consists of two species, the yellow-headed warbler and the Oriente warbler. Both species are found in forest and scrub, with the yellow-headed warbler ranging in the west of the island and the Oriente warbler in the east. The Cuban warblers are long and have similar yellow and grey plumage. The Cuban warblers are insectivores, with beetles forming a large part of the diet. Small reptiles and fruit are also taken. They feed in bushes and trees, in pairs or in small flocks during the non-breeding season, and are often the nucleus species for mixed-species feeding flocks with other birds, particularly migrants from North America. Taxonomy The genus ''Teretistris'' was long thought to sit in the New World warbler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and 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 building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epiphyte
An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tillandsia
''Tillandsia'' is a genus of around 650 species of evergreen, perennial flowering plants in the family Bromeliaceae, native to the forests, mountains and deserts of northern Mexico and south-eastern United States, Mesoamerica and the Caribbean to mid Argentina. Their leaves, more or less silvery in color, are covered with specialized cells (trichomes) capable of rapidly absorbing water that gathers on them. They are also commonly known as air plants because they are epiphytes, not needing soil for nourishment. They have a natural propensity to cling to whatever surfaces are readily available: telephone wires, tree branches, bark, bare rocks, etc. Their light seeds and a silky parachute facilitate their spread. Most ''Tillandsia'' species are epiphytes – which translates to 'upon a plant'. Some are aerophytes, which have a minimal root system and grow on shifting desert soil. Due to their epiphytic way of life, these plants will not grow in soil but live on the branches of tre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mixed-species Foraging Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.

Coleoptera
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Maestra
The Sierra Maestra is a mountain range that runs westward across the south of the old Oriente Province in southeast Cuba, rising abruptly from the coast. The range falls mainly within the Santiago de Cuba and in Granma Provinces. Some view it as a series of connecting ranges (Vela, Santa Catalina, Quemado Grande, Daña Mariana), which join with others to the west. At 1,974 m (6,476 ft), Pico Turquino is the range's – and the country's – highest point. The area is rich in minerals, especially copper, manganese, chromium, and iron. History The Sierra Maestra has a long history of guerrilla warfare, starting with the resistance of the Taínos under Guamá (died 1532), the Cimarrón Neo-Taíno nations escaped slave cultures, the Ten Years' War (1868–1878) and the Cuban War of Independence (1895–1898), and various minor conflicts such as the Race War of 1912, and the uprisings of Antonio Guiteras (died 1935) against Gerardo Machado (President of Cuba f ...
