Centre Hills
Centre Hills is a forest reserve on the island of Montserrat, a British Overseas Territory in the Leeward Islands of the Caribbean Sea. It forms one of the territory's Important Bird Areas (IBAs), which encompasses the forest reserve as well as additional habitat for the Montserrat oriole, the territory's endemic, and critically endangered, national bird. Description The 1112 ha IBA comprises the largest remnant of Montserrat's native forest. It encompasses the highlands of the northern half of the island from an elevation of 150 m up to the 741 m summit of Katy Hill. The terrain is steep, largely trackless, and riven by the ‘ghauts’, or ravines, that radiate into the islands's northern lowlands. Rainfall increases with altitude, and the vegetation changes from tropical dry forest at the lower elevations, through tropical evergreen forest to elfin forest at the summit. Most of the forest is secondary or regrowth, following historic land clearance for plantatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Succession
Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil. Many factors can affect secondary succession, such as trophic interaction, initial composition, and competition-colonization trade-offs. The factors that control the increase in abundance of a species during succession may be determined mainly by seed production and dispersal, micro climate; landscape structure (habitat patch size and distance to outside seed sources); bulk density, pH, and soil texture (sand and clay). Secondary succession is the ecological succession that occurs after the initial succession has been dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest Thrush
The forest thrush (''Turdus lherminieri'') is a species of bird in the family Turdidae. It was historically the sole species within the genus ''Cichlherminia'', however the AOU reclassified the species to the genus ''Turdus'' in 2009. This is a medium-sized thrush at 25–27 cm long and weighing 100–110 g. Like many thrushes, the forest thrush has brown upperparts with pale underparts showing a scaly pattern of coloration. However, for a thrush it has an unusually wide band of bare skin around each eye. It is endemic to the Lesser Antilles, an island group in the Caribbean. It can be found, though uncommon to rare, on Dominica, Guadeloupe, Montserrat, and Saint Lucia. Its natural habitat is tropical moist mountain forest. Two subspecies occur: the Montserrat race and the Dominica race, distinguished by the amount of scaling on the breast. The Dominica race has a white belly and scaled breast, the Montserrat race has scaling all the way from the breast through t ...

Brown Trembler
The brown trembler (''Cinclocerthia ruficauda'') is a species of bird in the family Mimidae, the mockingbirds and thrashers. It is found on the islands of Saba, St. Kitts, Nevis, Montserrat, Guadeloupe, Dominica and St. Vincent in the Lesser Antilles of the Caribbean Sea.Sibbald, E. (2020). Brown Trembler (''Cinclocerthia ruficauda''), version 1.0. In Birds of the World (T. S. Schulenberg, Editor). Cornell Lab of Ornithology, Ithaca, NY, USA. https://doi.org/10.2173/bow.brotre1.01 retrieved August 3, 2021 Taxonomy and systematics The taxonomy of genus ''Cinclocerthia'' is not fully resolved. The International Ornithological Committee (IOC) recognizes the brown trembler and the grey trembler (''C. gutturalis''). It divides the brown trembler into four subspecies, the nominate ''C. r. ruficauda'', ''C. r. pavida'', ''C. r. tremula'', and ''C. r. tenebrosa''. However, there is significant phylogenetic evidence that brown tremblers from Guadeloupe northwards may represent a separa ...

Pearly-eyed Thrasher
The pearly-eyed thrasher (''Margarops fuscatus'') is a bird in the thrasher family Mimidae. It is found on many Caribbean islands, from the Bahamas in the north to the Grenadines in the south, with an isolated subspecies on Bonaire. Description The pearly-eyed thrasher is the largest species in the Mimidae, growing to 28 to 30 cm (11 to 11.8 inches) in length. Taxonomy Its genus, ''Margarops'', is currently considered monotypic; formerly the scaly-breasted thrasher was placed in the same genus. However, ''M. fusctaus'' is now known to be closer to the ''Cinclocerthia'' tremblers. While this is not a migratory bird, considerable gene flow between populations appears to have taken place at least until fairly recently in its evolutionary history. There are four subspecies, two of which can be distinguished genetically: ''M. f. fuscatus'' (the nominate subspecies, which is found between the Greater Antilles and Antigua and Barbuda), and ''M. f. densirostris'' (oc ...

Scaly-breasted Thrasher
The scaly-breasted thrasher (''Allenia fusca'') is a species of bird in the family Mimidae. It is found throughout much of the Lesser Antilles of the Caribbean Sea. Taxonomy and systematics The scaly-breasted thrasher was originally placed in genus ''Margarops'' with the pearly-eyed thrasher (''M. fuscatus'') but is now in the monotypic genus ''Allenia''. It has five subspecies: *''A. f. hypenema'' Buden (1993) *''A. f. vincenti'' Kratter & Garrido (1996) *''A. f. atlantica'' Buden (1993) *''A. f. schwartzi'' Buden (1993) *''A. f. fusca'' Müller (1776) Description The scaly-breasted thrasher is approximately long and weighs with an average weight of . With its rather short and slightly decurved bill, this thrasher resembles a thrush. Adults of the nominate subspecies have a dark gray-brown head and upperparts with a reddish tinge on the rump. Their tail is a darker brownish black and its outer feathers have white tips. The folded wing shows a single white bar. Thei ...

Caribbean Elaenia
The Caribbean elaenia (''Elaenia martinica'') is a species of bird in the family Tyrannidae found in the West Indies and parts of Central America. Its natural habitats are tropical and subtropical dry broadleaf forest, subtropical or tropical moist lowland forest, and heavily degraded former forest. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Caribbean elaenia in his ''Ornithologie'' based on a specimen collected on the island of Martinique. He used the French name ''Le gobe-mouche hupé de la Martinique'' and the Latin ''Muscicapa Martinicana cristata''. 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 in 1766 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antillean Crested Hummingbird
The Antillean crested hummingbird (''Orthorhyncus cristatus'') is a species of hummingbird in the family Trochilidae. Found across Anguilla, Antigua and Barbuda, Barbados, Dominica, Grenada, Guadeloupe, Martinique, Montserrat, north-east Puerto Rico, Saba, Saint-Barthélemy, Saint Kitts and Nevis, Saint Lucia, Saint Martin, Saint Vincent and the Grenadines, Sint Eustatius, the British Virgin Islands, the U.S. Virgin Islands, and the Lesser Antilles, while it has also been recorded as a vagrant in Florida, USA. Taxonomy In 1743 the English naturalist George Edwards included an illustration and a description of the Antillean crested hummingbird in his ''A Natural History of Uncommon Birds''. He used the English name "The crested humming bird". Edwards based his hand-coloured etching on a specimen collected in the West Indies. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the Antillean crested hummingbird with ...
