Blacktoft Sands RSPB Reserve
Blacktoft Sands RSPB reserve is a nature reserve in the East Riding of Yorkshire, England. It is managed by the Royal Society for the Protection of Birds, which leases the site from Associated British Ports. Description The site is on the southern bank of the Ouse, west of its confluence with the River Trent, opposite the village of Blacktoft, and is a wetland. Being at the beginning of the Humber Estuary, the water is slightly saline. The reserve's tidal reedbed is the largest in England. It is managed using a mixture of grazing with our six konik horses, reed cutting and maintaining and excavation of pools within the reedbed. Wildlife As an RSPB reserve Blacktoft Sands is known for its birdlife. The headline species are wetland birds which are rare in Britain. Breeding birds include Western marsh harrier, great bittern and bearded reedling which are reedbed specialists, while the pied avocet prefers the saline lagoons. Hen harrier is a notable wintering species, joining the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pied Avocet
The pied avocet (''Recurvirostra avosetta'') is a large black and white wader in the avocet and stilt family, Recurvirostridae. They breed in temperate Europe and across the Palearctic to Central Asia then on to the Russian Far East. It is a migratory species and most winter in Africa or southern Asia. Some remain to winter in the mildest parts of their range, for example in southern Spain and southern England. The pied avocet is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. Taxonomy The pied avocet was one of the many bird species originally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'', where it was given the binomial name of ''Recurvirostra avosetta''. This species gets its English and scientific names from the Venetian word ''avosetta''. It appeared first in Ulisse Aldrovandi's ''Ornithologia'' (1603). While the name may refer to black and white outfits once wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chironomid
The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae. The name Chironomidae stems from the Ancient Greek word ''kheironómos'', "a pantomimist". Common names and biodiversity This is a large taxon of insects; some estimates of the species numbers suggest well over 10,000 world-wide. Males are easily recognized by their plumose antennae. Adults are known by a variety of vague and inconsistent common names, largely by confusion with other insects. For example, chironomids are known as "lake flies" in parts of Canada and Lake Winnebago, Wisconsin, but "bay flies" in the areas near the bay of Green Bay, Wisconsin. They are called "sand flies", "muckleheads", "muffleheads", "Canadian so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gammarus Chevreuxi
''Gammarus chevreuxi'' is a species of crustacean in the family Gammaridae. It was first described by Elsie Wilkins Sexton in 1913. The organism is very similar to ''Gammarus locusta'', but there are certain constant characteristic which set it apart, for example, the antennae, the fourth side-plates and the third uropods. It is found in various places in England, such as the Severn Estuary, and in Portugal. Eyes and heredity The eyes of ''G. chevreuxi'' are made up of black facets separated by white pigment. A mutation causes red facets. The recessive nature of the gene means that red-eyed populations breed true, being homozygous, while heterozygous black eyed populations may have either red-eyed or black-eyed offspring, in an illustration of Mendel's law of segregation Mendelian inheritance (also known as Mendelism) is a type of biological inheritance following the principles originally proposed by Gregor Mendel in 1865 and 1866, re-discovered in 1900 by Hugo de Vries ...

Amphipod
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as ''Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruff (bird)
The ruff (''Calidris pugnax'') is a medium-sized wading bird that breeds in marshes and wet meadows across northern Eurasia. This highly gregarious sandpiper is migratory and sometimes forms huge flocks in its winter grounds, which include southern and western Europe, Africa, southern Asia and Australia. The ruff is a long-necked, pot-bellied bird. This species shows marked sexual dimorphism; the male is much larger than the female (the reeve), and has a breeding plumage that includes brightly coloured head tufts, bare orange facial skin, extensive black on the breast, and the large collar of ornamental feathers that inspired this bird's English name. The female and the non-breeding male have grey-brown upperparts and mainly white underparts. Three differently plumaged types of male, including a rare form that mimics the female, use a variety of strategies to obtain mating opportunities at a lek, and the colourful head and neck feathers are erected as part of the elaborate mai ...

Spotted Redshank
The spotted redshank (''Tringa erythropus'') is a wader (shorebird) in the large bird family Scolopacidae. The genus name ''Tringa'' is the New Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek ''trungas'', a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific ''erythropus'' is from Ancient Greek ''eruthros'', "red", and ''pous'', "foot". It breeds across northern Scandinavia and the northern Palearctic and migrates south to the Mediterranean, the southern British Isles, France, tropical Africa, and tropical Asia for the winter. It is an occasional vagrant to Australia and North America. Taxonomy The spotted redshank was described by German zoologist Peter Simon Pallas in 1764 and given the binomial name ''Scolopax erythropus''. It is a monotypic species, with no recognised subspecies. Taxonomically, it forms a close-knit group with several other large ''Tringa'' species, with molecular sequencing showing ...

Eurasian Spoonbill
The Eurasian spoonbill (''Platalea leucorodia''), or common spoonbill, is a wading bird of the ibis and spoonbill family Threskiornithidae. The genus name ''Platalea'' is from Latin and means "broad", referring to the distinctive shape of the bill, and ''leucorodia'' is from Ancient Greek ''leukerodios'' "spoonbill", itself derived from ''leukos'', "white" and ''erodios'' "heron". In England it was traditionally known as the "shovelard", a name later used for the Northern Shoveller. Taxonomy and systematics A study of mitochondrial DNA of the spoonbills found that the Eurasian spoonbill is sister taxon to a clade containing the royal and black-faced spoonbills. The Eurasian spoonbill has three subspecies: * ''P. l. leucorodia'' – Linnaeus, 1758: nominate, occupies all the range except as below. * ''P. l. balsaci'' – Naurois & Roux, 1974: found on the islands off the Banc d'Arguin, Mauritania. * ''P. l. archeri'' – Neumann, 1928: found on the coasts of the Red Sea and So ...

Eurasian Wigeon
The Eurasian wigeon or European wigeon (''Mareca penelope''), also known as the widgeon or the wigeon, is one of three species of wigeon in the dabbling duck genus ''Mareca''. It is common and widespread within its Palearctic range. Taxonomy The Eurasian wigeon was described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' under the binomial name ''Anas penelope''. ''Anas'' is the Latin word for "duck", and ''penelope'' refers to a duck that was supposed to have rescued Penelope when she was thrown into the sea. Her name derives from Ancient Greek πήνη ''pene'', "braid" and ὤψ ''ops'' "appearance", from the ruse she used to deter suitors while her husband Ulysses was absent. Description This dabbling duck is long with a wingspan, and a weight of . The breeding male has grey flanks and back, with a black rear end, a dark green speculum and a brilliant white patch on upper wings, obvious in flight or at rest. It has a pink breast, white belly, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Teal
The Eurasian teal (''Anas crecca''), common teal, or Eurasian green-winged teal is a common and widespread duck that breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal. It is a highly gregarious duck outside the breeding season and can form large flocks. It is commonly found in sheltered wetlands and feeds on seeds and aquatic invertebrates. The North American green-winged teal (''A. carolinensis'') was formerly (and sometimes is still) considered a subspecies of ''A. crecca''. Taxonomy The Eurasian teal belongs to the "true" teals, a group of small ''Anas'' dabbling ducks closely related to the mallard (''A. platyrhynchos'') and its relatives; that latter group in fact seems to have evolved from a true teal. It forms a superspecies with the green-winged teal and the speckled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barn Owl
The barn owl (''Tyto alba'') is the most widely distributed species of owl in the world and one of the most widespread of all species of birds, being found almost everywhere except for the polar and desert regions, Asia north of the Himalayas, most of Indonesia, and some Pacific Islands. It is also known as the common barn owl, to distinguish it from the other species in its family, Tytonidae, which forms one of the two main lineages of living owls, the other being the typical owls (''Strigidae''). There are at least three major lineages of barn owl: the western barn owl of Europe, western Asia, and Africa; the eastern barn owl of southeastern Asia and Australasia; and the American barn owl of the Americas. Some taxonomic authorities classify barn owls differently, recognising up to five separate species; and further research needs to be done to resolve the disparate taxonomies. There is considerable variation of size and colour among the approximately 28 subspecies, but most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
