White-winged Warbler (Xenoligea Montana) (8082795709)
The white-winged warbler (''Xenoligea montana''), also called the white-winged ground-warbler, is a Vulnerable 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 The white-winged warbler is the only member of genus ''Xenoligea''. It was originally named ''Microligea montana'', sharing that genus with the green-tailed warbler (''M. palustris''), but was later recognized in its own genus. Those two species were originally placed in the New World wood warbler family Parulidae, but taxonomists were unsure they belonged there. DNA evidence published in the early 2010s showed they were not related to other wood warblers and in 2017, they were moved to the newly created family Phaenicophilidae. The two species in the genus ''Phaenicophilus'' were also moved there from the "true" tanager family Thraupidae. The white-winged warbler is monotypi ...

Primary Feather
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices (), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds have evolved to perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on them. Even flightless birds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xeno-canto
xeno-canto is a citizen science project and Information repository, repository in which volunteers record, upload and annotate recordings of Bird vocalization, birdsong and bird calls. Since it began in 2005, it has collected over 575,000 sound recordings from more than 10,000 species worldwide, and has become one of the biggest collections of bird sounds in the world. All the recordings are published under one of the Creative Commons licenses, including some with open licences. Each recording on the website is accompanied by a spectrogram and location data on a map displaying geographical variation. Data from xeno-canto has been re-used in many (a few thousand) scientific papers. It has also been the source of data for an annual challenge on automatic birdsong recognition ("BirdCLEF") since 2014, conducted as part of the Conference and Labs of the Evaluation Forum. The website is supported by a number of academic and birdwatching institutions worldwide, with its primary support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispaniolan Spindalis
The Hispaniolan spindalis (''Spindalis dominicensis'') is one of four species of bird in family Spindalidae. It is endemic to the Caribbean island of Hispaniola which is shared by Haiti and the Dominican Republic. Taxonomy and systematics Historically, the genus ''Spindalis'' consisted of a single polytypic species, ''Spindalis zena'' (with the common name of stripe-headed tanager), with eight recognized subspecies. The genus was in the "true" tanager family Thraupidae. Beginning in 1997, based primarily on morphological and vocalization differences, three of the subspecies were elevated to species status (including the Hispaniolan spindalis), and ''S. zena'' was renamed the western spindalis. Beginning in 2017, taxonomic systems moved the four spindalis species to the newly created family Spindalidae, which is not closely related to the tanagers. The Hispaniolan spindalis is monotypic. Description The Hispaniolan spindalis is about long and weighs . Adult males have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mixed-species Foraging Flocks
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.

Trema Micrantha
''Trema micrantha'', the Jamaican nettletree or capulin, is a plant species native to warmer parts of the Western Hemisphere. It has been reported from Mexico, Central America, tropical South America, the Virgin Islands, Jamaica, Cuba, Hispaniola, Puerto Rico, and southern Florida. Description ''Trema micrantha'' is a shrub or small tree up to 10 m tall. Leaves are egg-shaped, up to 9 cm long, green on top but covered with white, woolly pubescence underneath. Flowers are greenish-white. Fruits are yellow to bright reddish-range, up to 4 mm in diameter.

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Broadleaf Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Hispaniolan Pine Forests
The Hispaniolan pine forests are a subtropical coniferous forest ecoregion found on the Caribbean island of Hispaniola, which is shared by Haiti and the Dominican Republic. The ecoregion covers , or about 15% of the island. It lies at elevations greater than in the mountains of Hispaniola, extending from the Cordillera Central of the Dominican Republic and into the Massif du Nord of Haiti. It is surrounded at lower elevations by the Hispaniolan moist forests and Hispaniolan dry forests ecoregions, which cover the remainder of the island. Annual rainfall is . Flora The natural vegetation of the region consists primarily of stands of pino criollo (''Pinus occidentalis''). Pines are mixed with other conifers, including sabina ('' Juniperus gracilior'') and '' Podocarpus aristulatus'' (syn. ''P. buchii''). Below , pine forests are found on lateritic soils and are interspersed with areas of wet montane forest. Important broad-leaved species are '' Garrya fadyenii'' and '' Vac ...

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. Temperature varies from in open areas near the coast and averages around in higher area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
