Bahama Nuthatch
The Bahama nuthatch (''Sitta insularis'') is a nuthatch species Endemism, endemic to the Bahamian pineyards, pineyards of Grand Bahama island in the The Bahamas, Bahamas. It may be Extinction, extinct as of 2019. Description It has some notable differences from its closest relative, the brown-headed nuthatch (''S. pusilla''), including a darker brown facial stripe, a longer bill, shorter wings, and a unique warbling call. Taxonomy It was previously considered a subspecies of the brown-headed nuthatch by most taxonomic authorities. A 2020 study found further evidence for it being a distinct species, finding significant vocal differences based on voice recordings and a notable genetic difference from the brown-headed nuthatch that was even larger than that of some birds unanimously considered distinct species from their mainland relatives, such as the Bahama warbler (''Setophaga flavescens'') compared the yellow-throated warbler (''S. dominica'').

James Bond (ornithologist)
James Bond (January 4, 1900 – February 14, 1989) was an American ornithologist and expert on the birds of the Caribbean, having written the definitive book on the subject: '' Birds of the West Indies'', first published in 1936. He served as a curator of the Academy of Natural Sciences of Philadelphia. His name was appropriated by writer Ian Fleming for his fictional British spy of the same name; the real Bond enjoyed knowing his name was being used this way, and references to him permeate the resulting media franchise. Life and career Bond was born on January 4, 1900, in Philadelphia, Pennsylvania, the son of Margaret Reeves ( Tyson) and Francis Edward Bond. His interest in natural history was spurred by an expedition his father undertook in 1911 to the Orinoco Delta. Bond was educated at the Delancey School followed by St. Paul's School in Concord, New Hampshire, but after the death of his mother he moved with his father to the United Kingdom in 1914. There, he studied at Ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Nuthatches
The nuthatches () constitute a genus, ''Sitta'', of small passerine birds belonging to the family Sittidae. Characterised by large heads, short tails, and powerful bills and feet, nuthatches advertise their territory using loud, simple songs. Most species exhibit grey or bluish upperparts and a black eye stripe. Most nuthatches breed in the temperate or montane woodlands of the Northern Hemisphere, although two species have adapted to rocky habitats in the warmer and drier regions of Eurasia. However, the greatest diversity is in Southern Asia, and similarities between the species have made it difficult to identify distinct species. All members of this genus nest in holes or crevices. Most species are non-migratory and live in their habitat year-round, although the North American red-breasted nuthatch migrates to warmer regions during the winter. A few nuthatch species have restricted ranges and face threats from deforestation. Nuthatches are omnivorous, eating mostly insects, ...

Endemic Birds Of The Bahamas
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] |
Cozumel Thrasher
The Cozumel thrasher (''Toxostoma guttatum'') is a bird from the mockingbird family ( Mimidae), which is endemic to the island of Cozumel off the Yucatán Peninsula, Mexico. It is believed to be the most critically endangered species of bird in Mexico - if it indeed still exists, which is probable but not certain.ENS (2004) This bird is closely related to the long-billed and brown thrasher. It has been generally described as shy, but there have been descriptions to the contrary. It was once abundant throughout Cozumel before two hurricanes greatly affected its numbers. Invasive species are also thought to have impacted the population of the thrasher. Taxonomy The Cozumel thrasher was first described as ''Harporhynchus guttatus'' by Robert Ridgway in 1885. It has been described as a subspecies to its relative the long-billed thrasher, but was considered a separate species when it was determined in a 1998 study that it differed genetically more than five percent from both the long ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saffir–Simpson Scale
The Saffir–Simpson hurricane wind scale (SSHWS) classifies hurricanes—which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms—into five categories distinguished by the intensities of their sustained winds. This measuring system was formerly known as the Saffir–Simpson hurricane scale, or SSHS. To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at 10 m above the surface of at least 74 mph (64 kn, 119 km/h; Category 1). The highest classification in the scale, Category 5, consists of storms with sustained winds of at least 157 mph (137 kn, 252 km/h). The classifications can provide some indication of the potential damage and flooding a hurricane will cause upon landfall. The Saffir–Simpson hurricane wind scale is based on the highest wind speed averaged over a one-minute interval 10 m above th ...

Hurricane Dorian
Hurricane Dorian was an extremely powerful and catastrophic Category 5 Atlantic hurricane, which became the most intense tropical cyclone on record to strike the Bahamas, and tied for strongest landfall in the Atlantic basin. It is also regarded as the worst natural disaster in the Bahamas' recorded history. It was also one of the most powerful hurricanes recorded in the Atlantic Ocean in terms of 1-minute sustained winds, with those winds peaking at 185 mph (295 km/h). In addition, Dorian surpassed Hurricane Irma of 2017 to become the most powerful Atlantic hurricane on record outside of the Caribbean Sea. Dorian was the fourth named storm, second hurricane, the first major hurricane, and the first Category 5 hurricane of the 2019 Atlantic hurricane season. Dorian struck the Abaco Islands on September 1 with maximum sustained winds of 185 mph (295 km/h), tying with the 1935 Labor Day hurricane for the highest wind speeds of an Atlantic hurricane ...

Hurricane Matthew
Hurricane Matthew was an extremely powerful Atlantic hurricane which caused catastrophic damage and a humanitarian crisis in Haiti, as well as widespread devastation in the southeastern United States. The deadliest Atlantic hurricane since Hurricane Stan in 2005, and the first Category 5 Atlantic hurricane since Felix in 2007, Matthew was the thirteenth named storm, fifth hurricane and second major hurricane of the 2016 Atlantic hurricane season. It caused extensive damage to landmasses in the Greater Antilles, and severe damage in several islands of the Bahamas which were still recovering from Joaquin, which had pounded the archipelago nearly a year earlier. Matthew also approached the southeastern United States, but stayed just offshore, paralleling the Florida coastline. Originating from a tropical wave that emerged off Africa on September 22, Matthew developed into a tropical storm just east of the Lesser Antilles on September 28. It became a hurrica ...

Common Starling
The common starling or European starling (''Sturnus vulgaris''), also known simply as the starling in Great Britain and Ireland, is a medium-sized passerine bird in the starling family, Sturnidae. It is about long and has glossy black plumage with a metallic sheen, which is speckled with white at some times of year. The legs are pink and the bill is black in winter and yellow in summer; young birds have browner plumage than the adults. It is a noisy bird, especially in communal roosts and other gregarious situations, with an unmusical but varied song. Its gift for mimicry has been noted in literature including the ''Mabinogion'' and the works of Pliny the Elder and William Shakespeare. The common starling has about 12 subspecies breeding in open habitats across its native range in temperate Europe and across the Palearctic to western Mongolia, and it has been introduced to Australia, New Zealand, Canada, the United States, Mexico, Argentina, South Africa and Fiji.

House Sparrow
The house sparrow (''Passer domesticus'') is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of and a mass of . Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus ''Passer'', the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird. The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, and deserts away from human development. It feeds mostly on the seeds of grains and weeds, but it is an opportunistic eater and commonly eats insects and many o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
