Paraclaravis
''Paraclaravis'' is a genus that contains two species of doves that live in the Neotropics, with ranges in Middle America and South America. ''Paraclaravis'' doves have red eyes and pink legs, and the plumages of the males are primarily light grey-blue, and the females are primarily brown. Both sexes have a series of distinctive spots or bands on the wings. They are fairly arboreal for ground doves. ''Paraclaravis'' doves have a distinct fast and rocking flight pattern. They are found alone, in pairs or in small flocks in forests. Both species are generally local and rare, and appears to be associated with flowering bamboo. The genus contains two species, which were formerly included with the blue ground dove in the genus ''Claravis'': * Maroon-chested ground dove, ''Paraclaravis mondetoura'' * Purple-winged ground dove The purple-winged ground dove (''Paraclaravis geoffroyi'') is a critically endangered species of dove, native to the Atlantic forest, mainly near bamboo, i ...

Maroon-chested Ground Dove
The maroon-chested ground dove (''Paraclaravis mondetoura'') is a species of bird in the family Columbidae. It is found in Bolivia, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Panama, Peru, and Venezuela. Taxonomy and systematics The maroon-chested ground dove was originally placed in genus ''Claravis'' but a 2018 publication created the current genus ''Paraclaravis'' for it and the purple-winged ground dove (''P. geoffroyi'').Remsen, J.

Purple-winged Ground Dove
The purple-winged ground dove (''Paraclaravis geoffroyi'') is a critically endangered species of dove, native to the Atlantic forest, mainly near bamboo, in south-eastern Brazil, far eastern Paraguay, and northern-eastern Argentina (Misiones only). It is threatened by habitat loss and possibly the wild bird trade, and could potentially even be extinct due to its specialized requirements. Behavior It is a nomadic species that follows the masting events of certain species of ''Guadua'' bamboo of the Atlantic forest, namely takuarusu ('' G. chacoensis'') and yatevó ('' G. trinii''); it shares its trait with its closest relative, the maroon-chested ground-dove (''Paraclaravis mondetoura''), which instead specializes on Andean bamboo. This specialized lifestyle may be what led to such a dramatic decline in the species' population despite its relatively large former range, with the mass deforestation of the Atlantic forest in the late 20th century triggering an Allee effect akin ...

Blue Ground Dove
The blue ground dove (''Claravis pretiosa'') is a small New World tropical dove. It is a resident breeder from southeastern Mexico to northwestern Peru and northern Argentina, and on Trinidad in the Caribbean. Habitat and breeding The blue ground dove is relatively common in open woodland, forest edges, clearings and roadsides, especially in more humid areas. It is found from sea level to about 1200 m altitude. It builds a flimsy dish nest of twigs 1–11 m high in a tree and lays two white eggs. Description Blue ground doves are small pigeons, 20 cm long with a weight of 65-72 g. Adult males have blue-grey upperparts and paler grey underparts, becoming grey-white on the face. The flight feathers and outer tail feathers are blackish, and the wings are boldly spotted black (these spots often forming distinct bands). The iris is red or yellow, the bare eyering is green, and the legs are flesh-pink. The female has a grey-brown head neck and breast, becoming pale blue-grey on t ...

Doves
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotropics
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropics, tropical Ecoregion#Terrestrial, terrestrial ecoregions of the Americas and the entire South American temperate climate, temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Phytochorion, Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic Floristic Kingdom, Antarctic kingdom. The ...

Middle America (Americas)
Middle America is a subregion in the middle latitudes of the Americas. It usually includes Mexico, the 7 countries of Central America, and the 13 island countries and 18 territories of the Caribbean. Together with Northern America, they form the continent of North America. Colombia and Venezuela of South America are sometimes included in this subregion. The Caribbean is occasionally excluded from this subregion while Bermuda and The Guianas are infrequently included. Geography Physiographically, Middle America marks the territorial transition between Northern America and South America, connecting yet separating the two.Gonzalez, Joseph. 2004"Middle America: Bridging Two Continents"(ch. 17). ''The Complete Idiot's Guide to Geography.'' () New York: Alpha Books; pp. 213–7 On the west, the Middle American mainland comprises the tapering, isthmian tract of the American landmass between the southern Rocky Mountains in the southern United States and the northern tip of the ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...

Arboreal
Arboreal locomotion is the Animal locomotion, locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.Cartmill, M. (1985). Climbing. In ''Functional Vertebrate Morphology'', eds. M. Hildebrand D. M. Bramble K. F. Liem and D. B. Wake, pp. 73–88. Cambridge: Belknap Press. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as the tree snail. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in diverse ways. These challenges include moving on n ...
