Scaly-naped Pigeon
The scaly-naped pigeon (''Patagioenas squamosa''), also known as the red-necked pigeon, is a bird belonging to the family Columbidae. The species occurs throughout the Caribbean. Description The scaly-naped pigeon is a large slate grey pigeon (14–16 in), with maroon coloured plumage around the neck. The plumage on the species' nape appears scaly, explaining both the common and scientific names of the species. There is a bare patch of skin which surrounds the birds red eyes; this patch tends to be reddish in males and more yellow in females. The legs and the base of the bill of the species are red, while the remainder of the bill is light coloured. Distribution and habitat The range of the scaly-naped pigeon includes both the Greater Antilles (except Jamaica) and Lesser Antilles. The species tends to occur in rain forests, however it may also be found in drier lowland woodlands; the species is locally common near human settlements. Behaviour Scaly-naped pigeons are ...

Christ Church, Barbados
The parishes of Barbados, parish of Christ Church is one of eleven historic political divisions of Barbados. It has a land area of and is found at the southern end of the island. Christ Church has survived by name as one of the original six parishes created in 1629 by Governor Sir William Tufton. The parish contains the Sir Grantley Adams International Airport as well as the last remaining mangrove swamp in the country, the Graeme Hall Nature Sanctuary. Under Barbados's historic vestry, the main Christ Church Parish Church, parish church was originally seated near Dover. After it and the courtyard were destroyed by flood in 1669, the Church of England parish church, main parish church moved to Oistins, Christ Church, Barbados, Oistins area, becoming the main town and former Christ Church Parish Church, capital of the parish.

Bird Egg
Bird eggs are laid by the females and range in quantity from one (as in condors) to up to seventeen (the grey partridge). Clutch size may vary latitudinally within a species. Some birds lay eggs even when the eggs have not been fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs. Anatomy All bird eggs contain the following components: * The embryo is the immature developing chick * The amnion is a membrane that initially covers the embryo and eventually fills with amniotic fluid, provides the embryo with protection against shock from movement * The allantois helps the embryo obtain oxygen and handles metabolic waste * The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo * The vitellus, or yolk, is the nutrient-bearing portion of the egg, containing most of its fat, minerals, and many of its proteins and blood vessels * The alb ...

Birds Of The Dominican Republic
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. Bird ...

Endemic Birds Of The Caribbean
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] |

Patagioenas
''Patagioenas'' is a genus of New World pigeons whose distinctness from the genus ''Columba'' was long disputed but ultimately confirmed. It is basal to the ''Columba''-''Streptopelia'' radiation. Their ancestors diverged from that lineage probably over 8 million years ago. While the biogeographic pattern of this group suggests that the ancestors of the typical pigeons and turtle-doves settled the Old World from the Americas, ''Patagioenas'' may just as well be the offspring of Old World pigeons which only radiated into different genera later, given that the cuckoo-doves (''Macropygia'') of Southeast Asia also seem to be closely related.Johnson ''et al.'' (2001), Cheke (2005) Taxonomy The genus ''Patagioenas'' was introduced by the German naturalist Ludwig Reichenbach in 1853 with the white-crowned pigeon (''Patagioenas leucocephala'') as the type species. The genus name combines the Ancient Greek ''patageō'' meaning "to clatter" and ''oinas'' meaning "pigeon". There are 17 s ...

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 ...

Seeds
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general meaning that anteda ...
