Antrostomus Noctitherus
The Puerto Rican nightjar or Puerto Rican Whip-poor-will (''Antrostomus noctitherus'') is a bird in the nightjar family found in the coastal dry scrub forests in localized areas of southwestern Puerto Rico. It was described in 1916 from bones found in a cave in north central Puerto Rico and a single skin specimen from 1888, and was considered extinct until observed in the wild in 1961. The current population is estimated as 1,400-2,000 mature birds. The species is currently classified as Endangered due to pressures from habitat loss. Description Puerto Rican nightjars, whose song is composed of rapid "''whip''" notes, are small birds about 22–23 cm in length, weighing 39-41 g. Similar to the Antillean nighthawk, the species has a mottled, black, brown and gray colored plumage which serves as camouflage while the bird is perched on the ground. Males have a black throat with a white thin horizontal line. There are white spots on the lower part of the tail which are visibl ...

IUCN Red List Of Threatened Species
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 International Union for Conservation of Nature, 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.

Birds Described In 1919
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 Puerto Rico
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] |
Antrostomus
''Antrostomus'' is a genus of nightjars formerly included in the genus '' Caprimulgus''. They are medium-sized nocturnal birds with long pointed wings, short legs and short bills. ''Antrostomus'' nightjars are found in the New World, and like other nightjars they usually nest on the ground. They are mostly active in the late evening and early morning or at night, and feed predominantly on moths and other large flying insects. Most have small feet, of little use for walking, and their soft plumage is cryptically coloured to resemble bark or leaves. They have relatively long bills and rictal bristles. Some species, unusually for birds, perch along a branch, rather than across it, which helps to conceal them during the day. Temperate species are strongly migratory, wintering in the tropics. Many have repetitive and often mechanical songs. These species were formerly placed in the genus '' Caprimulgus'' but were moved to the resurrected genus ''Antrostomus'' based on the results o ...

List Of Vieques Birds
This is a list of birds recorded in the island of Vieques. Vieques is an island municipality of Puerto Rico located off the east coast of the main island of Puerto Rico, south of Culebra island and west of the Virgin Islands. It has a total area of 348.15 km2, of which only 135 km2 is land area. On May 1, 2001, the western end of Vieques National Wildlife Refuge was established and on May 1, 2003, the same day as the exit of the U.S. Navy from the island, the eastern end of the refuge was established. There are a total of 196 species recorded from the island of Vieques as of July 2022, according to ''Bird Checklists of the World''. Some species, such as the Puerto Rican parrot, have been extirpated from the island but are, nonetheless, included in this list. This list presents the following information for each species: common and scientific name of each species. This list is presented in the taxonomic sequence of the ''Check-list of North and Middle American Bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Puerto Rican Birds
This is a list of the bird species recorded in the archipelago of Puerto Rico, which consists of the main island of Puerto Rico, two island municipalities off the east coast (Vieques and Culebra), three uninhabited islands off the west coast ( Mona, Monito and Desecheo) and more than 125 smaller cays and islands. The avifauna of Puerto Rico included a total of 385 species as of July 2022, according to ''Bird Checklists of the World''. Of them, 201 are accidental, two have been extirpated, and one is believed to be extinct. Seventeen species are endemic. Non-native species are common; 43 listed here were introduced by humans. Individuals of many other species (mostly parrots, finches, and waxbills) are flying free, presumably after escaping or being released from captivity. For example, a 2018 study on introduced Psittacidae on the island found at least 46 species present, of which 24% are only found in the pet trade (captivity), 48% have been observed in the wild (but are n ...

Fauna Of Puerto Rico
The fauna of Puerto Rico is similar to other island archipelago faunas, with high endemism, and low, skewed taxonomic diversity. Bats are the only extant native terrestrial mammals in Puerto Rico. All other terrestrial mammals in the area were introduced by humans, and include species such as cats, goats, sheep, the small Indian mongoose, and escaped monkeys. Marine mammals include dolphins, manatees, and whales. Of the 349 bird species, about 120 breed in the archipelago, and 47.5% are accidental or rare. The most recognizable and famous animal of Puerto Rico is probably the common coquí, a small endemic frog, and one of the 86 species that constitute Puerto Rico's herpetofauna. Some native freshwater fish inhabit Puerto Rico, but some species, introduced by humans, have established populations in reservoirs and rivers. The low richness-high diversity pattern is also apparent among invertebrates, which constitutes most of the archipelago's fauna. The arrival of the first peo ...

Small Indian Mongoose
The small Indian mongoose (''Urva auropunctata'') is a mongoose species native to Iraq and northern South Asia; it has also been introduced to many regions of the world, such as several Caribbean and Pacific islands. Taxonomy ''Mangusta auropunctata'' was the scientific name proposed by Brian Houghton Hodgson in 1836 for a mongoose specimen collected in central Nepal. It was later classified in the genus ''Herpestes'', but all Asian mongooses are now thought to belong in the genus ''Urva''. In the 19th and 20th centuries, several zoological specimens were described: *''Mangusta pallipes'' proposed by Edward Blyth in 1845 were mongooses observed in Kandahar, Afghanistan. *''Herpestes palustris'' proposed by R. K. Ghose in 1965 was an adult male mongoose collected in a swamp on the eastern fringe of Kolkata, India. The small Indian mongoose was once considered a subspecies of the Javan mongoose (''H. javanicus''). Genetic analysis of hair and tissue samples from 18 small Indian an ...
