Actitis
''Actitis'' is a small genus of waders, comprising just two very similar bird species. Taxonomy The genus ''Actitis'' was introduced in 1811 by the German zoologist Johann Illiger. The genus name is from Ancient Greek ''aktites'', "coast-dweller" from ''akte'', "coast". The type species is the common sandpiper. The genus is sister to the genus ''Tringa'' that contains the shanks and the tattlers. The genus contains two species: * Common sandpiper, ''Actitis hypoleucos'', of Eurasia * Spotted sandpiper, ''Actitis macularia'' of North America Description These are both small migratory waders, greyish brown on top and white underneath, with a distinctive stiff-winged flight low over the water. The plumages are very similar, apart from spotted sandpipers' distinctive breeding plumage, and suspected out-of-range vagrants must be carefully observed for identification to species. Both species have short yellow or yellowish legs and a medium bill. These are not gregarious birds and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actitis Macularia
The spotted sandpiper (''Actitis macularius'') is a small shorebird. Together with its sister species the common sandpiper (''A. hypoleucos''), it makes up the genus ''Actitis''. They replace each other geographically; stray birds may settle down with breeders of the other species and hybridize. Taxonomy The spotted sandpiper was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his '' Systema Naturae'' under the binomial name ''Tringa macularia''. The type locality is Pennsylvania. The species is now placed together with common sandpiper in the genus ''Actitis'' that was introduced in 1811 by the German zoologist Johann Illiger. The genus name ''Actitis'' is from Ancient Greek ''aktites'' meaning "coast-dweller" from ''akte'' meaning "coast". The specific epithet ''macularius'' is Latin meaning "spotted". The species is monotypic: no subspecies are recognised. Description Adults have short yellowish legs and an orange bill with ...

Common Sandpiper
The common sandpiper (''Actitis hypoleucos'') is a small Palearctic wader. This bird and its American sister species, the spotted sandpiper (''A. macularia''), make up the genus ''Actitis''. They are parapatric and replace each other geographically; stray birds of either species may settle down with breeders of the other and hybridize. Hybridization has also been reported between the common sandpiper and the green sandpiper, a basal species of the closely related shank genus ''Tringa''. Taxonomy The common sandpiper was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his '' Systema Naturae'' under the binomial name ''Tringa hypoleucos''. The species is now placed together with the spotted sandpiper in the genus ''Actitis'' that was introduced in 1811 by the German zoologist Johann Karl Wilhelm Illiger.

Tringa
''Tringa'' is a genus of waders, containing the shanks and tattlers. The genus name ''Tringa'' is the New Latin name given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1599. They are mainly freshwater birds, often with brightly coloured legs as reflected in the English names of six species, as well as the specific names of two of these and the green sandpiper. They are typically associated with northern hemisphere temperate regions for breeding. Some of this group—notably the green sandpiper—nest in trees, using the old nests of other birds, usually thrushes. The willet and the tattlers have been found to belong in ''Tringa''; these genus changes were formally adopted by the American Ornithologists' Union in 2006. The present genus in the old, more limited sense was even further subdivided into ''Tringa'' proper and ''Totanus'', either as subgenera or as full genera. The available DNA sequence data suggests however that neither of these is monophyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalarope
__NOTOC__ A phalarope is any of three living species of slender-necked shorebirds in the genus ''Phalaropus'' of the bird family Scolopacidae. Phalaropes are close relatives of the shanks and tattlers, the ''Actitis'' and Terek sandpipers, and also of the turnstones and calidrids. They are especially notable for two things: their unusual nesting behavior, and their unique feeding technique. Two species, the red or grey phalarope (''Phalaropus fulicarius'') and the red-necked phalarope (''P. lobatus'') breed around the Arctic Circle and winter on tropical oceans. Wilson's phalarope (''P. tricolor'') breeds in western North America and migrates to South America. All are in length, with lobed toes and a straight, slender bill. Predominantly grey and white in winter, their plumage develops reddish markings in summer. Taxonomy The genus ''Phalaropus'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the red phalarope (''Phalaropus fulicarius'') as t ...

Fresh Water
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh ...

Forage
Forage is a plant material (mainly plant leaves and stems) eaten by grazing livestock. Historically, the term ''forage'' has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage. While the term ''forage'' has a broad definition, the term ''forage crop'' is used to define crops, annual or biennial, which are grown to be utilized by grazing or harvesting as a whole crop. Common forages Grasses Grass forages include: *'' Agrostis'' spp. – bentgrasses **''Agrostis capillaris'' – common bentgrass **''Agrostis stolonifera'' – creeping bentgrass *''Andropogon hallii'' – sand bluestem *''Arrhenatherum elatius'' – false oat-grass *'' Bothriochloa bladhii'' – Australian bluestem *''Bothriochloa pertusa'' – hurricane grass *''Brachiaria decumbens'' – Surinam grass *''Brachiaria humidicola'' – ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tattler (bird)
The tattlers are the two very similar bird species in the shorebird genus ''Tringa''. They formerly had their own genus, ''Heteroscelus''. The old genus name means "different leg" in Greek, referring to the leg scales that differentiate the tattlers from their close relatives, the shanks. The species are: * Grey-tailed tattler, ''Tringa brevipes'' (formerly ''Heteroscelus brevipes'') * Wandering tattler, ''Tringa incana'' (formerly ''Heteroscelus incanus'') Tattlers resemble a common redshank (''T. totanus'') in shape and size, but not in color. Their upper parts, underwings, face and neck are greyish, and the belly and the weak supercilium are white, with some greyish streaking on the underside in breeding plumage. They have short yellowish legs and a bill with a pale base and dark tip.Hayman ''et al.'' (1986) Certain identification to species depends on details like the length of the nasal groove and scaling on the tarsus. Birds in breeding plumage can also (with some experi ...

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...
