Sphyrapicus Varius
The yellow-bellied sapsucker (''Sphyrapicus varius'') is a medium-sized woodpecker that breeds in Canada and the northeastern United States. Taxonomy The yellow-bellied sapsucker was described and illustrated using a hand-coloured plate by the English naturalist Mark Catesby in his ''The Natural History of Carolina, Florida and the Bahama Islands'' which was published between 1729 and 1732. When in 1766 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the twelfth edition, he included the yellow-bellied sapsucker, coined the binomial name ''Picus varius'' and cited Catesby's book. The specific epithet ''varius'' is the Latin word meaning "various", "diverse" or "variegated". Linnaeus specified the type locality as ''America septentrionali'' (North America) but the locality is now restricted to South Carolina. The yellow-bellied sapsucker is now placed in the genus ''Sphyrapicus'' that was erected in 1858 by the American naturalist Spencer Baird with the ye ...

Cuba
Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is an island country comprising the island of Cuba, as well as Isla de la Juventud and several minor archipelagos. Cuba is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet. Cuba is located east of the Yucatán Peninsula (Mexico), south of both the American state of Florida and the Bahamas, west of Hispaniola ( Haiti/Dominican Republic), and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The official area of the Republic of Cuba is (without the territorial waters) but a total of 350,730 km² (135,418 sq mi) including the exclusive economic zone. Cuba is the second-most populous country in the Caribbean after Haiti, with over 11 million inhabitants. The territory that is now Cuba was inhabited by the Ciboney people from the 4th millennium BC with the Gua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-naped Sapsucker
The red-naped sapsucker (''Sphyrapicus nuchalis'') is a medium-sized North American woodpecker. Long thought to be a subspecies of the yellow-bellied sapsucker, it is now known to be a distinct species. Systematics The red-naped sapsucker is one of four North American woodpeckers in the genus '' Sphyrapicus''. It has no subspecies. First described by Spencer Fullerton Baird in 1858, it was initially thought to be a subspecies of the yellow-bellied sapsucker. However, there are significant genetic differences between this species and the yellow-bellied sapsucker, and the American Ornithologists' Union recognized it as a distinct species in the seventh edition of its North American birds checklist, published in 1998. Genetic analysis has shown that the red-naped sapsucker is a sister species with (and very closely related to) the red-breasted sapsucker, and that these two species form a superspecies with the yellow-bellied sapsucker. All three species are known to hybridize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
