Drumming (snipe)
Drumming (also called bleating or winnowing) is a sound produced by snipe as part of their courtship display flights.Van Casteren, A, et al. “Sonation in the Male Common Snipe (Capella Gallinago Gallinago L.) Is Achieved by a Flag-like Fluttering of Their Tail Feathers and Consequent Vortex Shedding.” ''The Journal of Experimental Biology'', vol. 213, no. 9, 2010, pp. 1602–1608. The sound is produced mechanically (rather than vocally) by the vibration of the outer tail feathers when flying in a downwards, swooping motion. The drumming display is usually crepuscular, though it can also be heard at any point throughout the breeding season, as well as sporadically during their migration period. Drumming is commonly heard within the context of a mating display, but it can also be displayed as means of distraction when conspecific intruders or potential predators are in the area — this can benefit male snipe in attracting a female mate. The weather can also have an impact on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbule
Feathers are epidermal growths that form a distinctive outer covering, or plumage, on both avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates and a premier example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant birds from other living groups. Although feathers cover most of the bird's body, they arise only from certain well-defined tracts on the skin. They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and protection. Plumology (or plumage science) is the name for the science that is associated with the study of feathers. Feathers have a number of utilitarian, cultural, and religious uses. Feathers are both soft and excellent at trapping heat; thus, they are sometimes used in high-class bedding, especially pillows, blankets, and mattresses. They are also used as filling for winter clothin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Sonation
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 swimm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallinago
''Gallinago'' is a genus of birds in the wader family Scolopacidae, containing 18 species. Taxonomy The name ''Gallinago'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 as a subdivision of the genus ''Scolopax''. Brisson did not use Carl Linnaeus's binomial system of nomenclature and although many of Brisson's genera had been adopted by ornithologists, his subdivision of genera were generally ignored. Instead, the erection of the genus ''Gallinago'' for the snipes was credited to the German zoologist Carl Ludwig Koch in a book published in 1816. But in 1920 it was discovered that the German naturalist Johann Samuel Traugott Frenzel had erected the genus ''Capella'' for the snipes in 1801. As his publication predated Koch's use of ''Gallinago'' it took precedence. The American Ornithologists' Union switched to ''Capella'' in 1921 and in 1934 the American ornithologist James L. Peters used ''Capella'' for the woodcocks in his influential ''Check-list of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coenocorypha
The austral snipes, also known as the New Zealand snipes or tutukiwi, are a genus, ''Coenocorypha'', of tiny birds in the sandpiper family, which are now only found on New Zealand's outlying islands. There are currently three living species and six known extinct species, with the Subantarctic snipe having three subspecies, including the Campbell Island snipe discovered as recently as 1997. The genus was once distributed from Fiji, New Caledonia and Norfolk Island, across New Zealand and southwards into New Zealand's subantarctic islands, but predation by introduced species, especially rats, has drastically reduced their range. Taxonomy and range The relationship between ''Coenocorypha'' snipe and the snipes of the genus ''Gallinago'' is uncertain. ''Coenocorypha'' is sometimes thought to be a relict taxon of an ancient lineage;Tennyson, A., & Martinson, P. (2006). ''Extinct Birds of New Zealand''. Te Papa Press, Wellington . however, insufficient research has been done to prove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandpipers
Sandpipers are a large family, Scolopacidae, of waders. They include many species called sandpipers, as well as those called by names such as curlew and snipe. The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of beak, bills enable different species to feed in the same habitat, particularly on the coast, without direct competition for food. Sandpipers have long bodies and legs, and narrow wings. Most species have a narrow bill, but otherwise the form and length are quite variable. They are small to medium-sized birds, measuring in length. The bills are sensitive, allowing the birds to feel the mud and sand as they probe for food. They generally have dull plumage, with cryptic brown, grey, or streaked patterns, although some display brighter colours during the breeding season. Most species nest in open areas, and defend their territories with aerial displays. The Bird nest, nest itself is a simple scrape in the ground, in whic ...

Thor
Thor (; from non, Þórr ) is a prominent god in Germanic paganism.

Walrus
The walrus (''Odobenus rosmarus'') is a large flippered marine mammal with a discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. The walrus is the only living species in the family Odobenidae and genus ''Odobenus''. This species is subdivided into two subspecies: the Atlantic walrus (''O. r. rosmarus''), which lives in the Atlantic Ocean, and the Pacific walrus (''O. r. divergens''), which lives in the Pacific Ocean. Adult walrus are characterised by prominent tusks and whiskers, and their considerable bulk: adult males in the Pacific can weigh more than and, among pinnipeds, are exceeded in size only by the two species of elephant seals. Walruses live mostly in shallow waters above the continental shelves, spending significant amounts of their lives on the sea ice looking for benthic bivalve mollusks to eat. Walruses are relatively long-lived, social animals, and they are considered to be a " keyston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
