List Of Birds Of Grenada
This is a list of the bird species recorded in Grenada. The avifauna of Grenada included a total of 197 species according to ''Bird Checklists of the World'' as of July 2022. Of them, one is endemic, six have been introduced by humans, and 127 are rare or accidental. One species on the list has been extirpated and one is probably extinct. This list is presented in the taxonomic sequence of the ''Check-list of North and Middle American Birds'', 7th edition through the 63rd Supplement, published by the American Ornithological Society (AOS). Common and scientific names are also those of the ''Check-list'', except that the common names of families are from the Clements taxonomy because the AOS list does not include them. The following tags have been used to highlight several categories of occurrence. * (A) Accidental - a species that rarely or accidentally occurs in Grenada * (E) Endemic - a species endemic to Grenada * (I) Introduced - a species introduced by humans either dir ...

Fulvous Whistling-duck
The fulvous whistling duck or fulvous tree duck (''Dendrocygna bicolor'') is a species of whistling duck that breeds across the world's tropical regions in much of Mexico and South America, the West Indies, the southern United States, sub-Saharan Africa and the Indian subcontinent. It has plumage that is mainly reddish brown, long legs and a long grey bill, and shows a distinctive white band across its black tail in flight. Like other members of its ancient lineage, it has a whistling call which is given in flight or on the ground. Its preferred habitat consists of wetlands with plentiful vegetation, including shallow lakes and paddy fields. The nest, built from plant material and unlined, is placed among dense vegetation or in a tree hole. The typical clutch is around ten whitish eggs. The breeding adults, which pair for life, take turns to incubate, and the eggs hatch in 24–29 days. The downy grey ducklings leave the nest within a day or so of hatching, but the parents contin ...

Cracidae
The chachalacas, guans and curassows are birds in the family Cracidae. These are species of tropical and subtropical Central and South America. The range of one species, the plain chachalaca, just reaches southernmost parts of Texas in the United States. Two species, the Trinidad piping guan and the rufous-vented chachalaca occur on the islands of Trinidad and Tobago respectively. Systematics and evolution The family Cracidae was introduced (as Craxia) by the French polymath Constantine Samuel Rafinesque in 1815. The Cracidae are an ancient group related to the Australasian mound-builders. They are sometimes united with these in a distinct order, "Craciformes", but this is not supported by more recent research which suggests that either is a well-marked, basal lineage of Galliformes. Phylogeny Cladogram based on the study by De Chen and collaborators published in 2021. The numbers of species are from the list maintained by Frank Gill, Pamela Rasmussen and David Donsker on beh ...

Galliformes
Galliformes is an order of heavy-bodied ground-feeding birds that includes turkeys, chickens, quail, and other landfowl. Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds. The order contains about 290 species, inhabiting every continent except Antarctica, and divided into five families: Phasianidae (including chicken, quail, partridges, pheasants, turkeys, peafowl (peacocks) and grouse), Odontophoridae (New World quail), Numididae (guinea fowl), Cracidae (including chachalacas and curassows), and Megapodiidae (incubator birds like malleefowl and brush-turkeys). They adapt to most environments except for innermost deserts and perpetual ice. Many gallinaceous species are skilled runners and escape predators by running rather than flying. Males of most species are more colorful than the females, with often elaborate courtship behaviors t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruddy Duck
The ruddy duck (''Oxyura jamaicensis'') is a duck from North America and one of the stiff-tailed ducks. The genus name is derived from Ancient Greek ''oxus'', "sharp", and ''oura'', "tail", and ''jamaicensis'' is "from Jamaica". Taxonomy The ruddy duck was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the other ducks, geese and swans in the genus ''Anas'' and coined the binomial name ''Anas jamaicensis''. Gmelin based his description on the "Jamaica shoveler" that had been described in 1785 by the English ornithologist John Latham from a specimen that he had received from Jamaica. The ruddy duck is now placed with five other species in the genus '' Oxyura'' that was introduced in 1828 by the French naturalist Charles Lucien Bonaparte. The genus name is derived from Ancient Greek ''oxus'', meaning "sharp", and ''oura'' meaning "tail". The specific epithet ' ...

Masked Duck
The masked duck (''Nomonyx dominicus'') is a tiny stiff-tailed duck ranging through the tropical Americas. They are found from Mexico to South America and also in the Caribbean. Primarily not migratory, masked ducks are reported as very uncommon vagrants in the southernmost United States, along the Mexican border and in Florida. As of 2000, the conservation status for masked ducks in Texas is 3,800 birds. On April 1, 1962, it was recorded from Lowndes County, Georgia, where it was photographed by Alexander Wetmore. The only member of the genus ''Nomonyx'', it is intermediate between the rather primitive black-headed duck (''Heteronetta'') and the very apomorphic true stiff-tailed ducks. It is sometimes included with the latter in the genus '' Oxyura'', but apparently the masked ducks now are the descendants of a missing link in the Oxyurini evolution, having changed but little for millions of years. Breeding adult males have a rust-colored body with a black face and mottled win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Scaup
The lesser scaup (''Aythya affinis'') is a small North American diving duck that migrates south as far as Central America in winter. It is colloquially known as the little bluebill or broadbill because of its distinctive blue bill. The origin of the name scaup may stem from the bird's preference for feeding on scalp—the Scottish word for clams, oysters, and mussels; however, some credit it to the female's discordant scaup call as the name's source. It is apparently a very close relative of the Holarctic greater scaup or "bluebill" (''A. marila''), with which it forms a superspecies. The scientific name is derived from Ancient Greek ''aithuia'' an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin, ''affinis'' "related to", from its resemblance to the greater scaup. Description Adults are long, on average. The species can weigh ; males weigh on average and females weigh noticeably less, at on average. Wing lengths (not wingspans) are abou ...

Ring-necked Duck
The ring-necked duck (''Aythya collaris'') is a diving duck from North America commonly found in freshwater ponds and lakes. The scientific name is derived from Greek , an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin ''collaris'', "of the neck" from ''collum'', "neck". Description Ring-necked ducks are small to medium-sized diving ducks with the following length, weight, and wingspan measurements: * Length: 15.3-18.1 in (39-46 cm) * Weight: 17.3-32.1 oz (490-910 g) * Wingspan: 24.4-24.8 in (62-63 cm) The adult male is similar in color pattern to the Eurasian tufted duck, its relative. Males are a little bit bigger than the female. It has two white rings surrounding its gray bill, a shiny black angular head, black back, white line on the wings, a white breast and yellow eyes. The adult female has a grayish brown angular head and body with a dark brown back, a dark bill with a more subtle light band than the male, grayish-bl ...

Green-winged Teal
The green-winged teal (''Anas carolinensis'') is a common and widespread duck that breeds in the northern areas of North America except on the Aleutian Islands. It was considered Conspecificity, conspecific with the Eurasian teal (''A. crecca'') for some time, but has since been split into its own species. The American Ornithological Society continues to debate this determination, however nearly all other authorities consider it distinct based on behavioral, morphological, and molecular evidence. The scientific name is from Latin ''Anas'', "duck" and ''carolinensis'', "of Province of Carolina, Carolina". This dabbling duck is strongly bird migration, migratory and winters far south of its breeding range. It is highly gregarious outside of the breeding season and will form large flocks. In flight, the fast, twisting flocks resemble waders. Taxonomy The green-winged teal was Species description, formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revi ...

Northern Pintail
The pintail or northern pintail (''Anas acuta'') is a duck species with wide geographic distribution that breeds in the northern areas of Europe and across the Palearctic and North America. It is migratory and winters south of its breeding range to the equator. Unusually for a bird with such a large range, it has no geographical subspecies if the possibly conspecific duck Eaton's pintail is considered to be a separate species. This is a large duck, and the male's long central tail feathers give rise to the species' English and scientific names. Both sexes have blue-grey bills and grey legs and feet. The drake is more striking, having a thin white stripe running from the back of its chocolate-coloured head down its neck to its mostly white undercarriage. The drake also has attractive grey, brown, and black patterning on its back and sides. The hen's plumage is more subtle and subdued, with drab brown feathers similar to those of other female dabbling ducks. Hens make a coarse ...

White-cheeked Pintail
The white-cheeked pintail (''Anas bahamensis''), also known as the Bahama pintail or summer duck, is a species of dabbling duck. It was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' under its current scientific name. Distribution and habitat It is found in the Caribbean, South America, and the Galápagos Islands. It occurs on waters with some salinity, such as brackish lakes, estuaries and mangrove swamps. There are three subspecies: * ''A. b. bahamensis''—lesser Bahama pintail—in the Caribbean, and a vagrant to southern Florida * ''A. b. rubirostris''—greater Bahama pintail—in South America; it may be partly migratory, breeding in Argentina and wintering further north. * ''A. b. galapagensis''—Galápagos pintail—in the Galápagos Islands Description Like many southern ducks, the sexes are similar. It is mainly brown with white cheeks and a red-based grey bill (young birds lack the pink). It cannot be confused with any ot ...

American Wigeon
The American wigeon (''Mareca americana''), also known as the baldpate, is a species of dabbling duck found in North America. Formerly assigned to ''Anas'', this species is classified with the other wigeons in the dabbling duck genus ''Mareca''. It is the New World counterpart of the Eurasian wigeon. Taxonomy The American wigeon was formally described in 1789 by German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with all the other ducks, geese and swans in the genus ''Anas'' and coined the binomial name ''Anas americana''. Gmelin based his description on Edme-Louis Daubenton's hand-colour plate of "Le Canard Jensen, de la Louisiane" and Thomas Pennant's description of the "American wigeon" in his ''Arctic Zoology''. Pennant had been sent a specimen from New York. The American wigeon is now placed with the Eurasian wigeon and three other dabbling ducks in the genus ''Mareca'' that was introduced in 182 ...
