Grey Heron
The grey heron (''Ardea cinerea'') is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water or stalking its prey through the shallows. Standing up to tall, adults weigh from . They have a white head and neck with a broad black stripe that extends from the eye to the black crest. The body and wings are grey above and the underparts are greyish-white, with some black on the flanks. The long, sharply pointed beak is pinkish-yellow and the legs are brown. The birds breed colonially in spring in "heronries", usually building their nests high in trees. A clutch of usually three to five bluish-gre ...

Moorhen
Moorhens—sometimes called marsh hens—are medium-sized water birds that are members of the rail family (Rallidae). Most species are placed in the genus ''Gallinula'', Latin for "little hen". They are close relatives of coots. They are often referred to as (black) gallinules. Recently, one of the species of ''Gallinula'' was found to have enough differences to form a new genus '' Paragallinula'' with the only species being the lesser moorhen (''Paragallinula angulata''). Two species from the Australian region, sometimes separated in , are called "native hens" (also native-hen or nativehen). The native hens differ visually by shorter, thicker and stubbier toes and bills, and longer tails that lack the white signal pattern of typical moorhens.Boles (2005) Description These rails are mostly brown and black with some white markings in plumage colour. Unlike many of the rails, they are usually easy to see because they feed in open water margins rather than hidden in reedbe ...

Coot
Coots are medium-sized water birds that are members of the rail family, Rallidae. They constitute the genus ''Fulica'', the name being the Latin term for "coot". Coots have predominantly black plumage, and—unlike many rails—they are usually easy to see, often swimming in open water. They are close relatives of the moorhen. However, the Coot typically appears 'dumpier' and lacks the distinctive red frontal face of the moorhen. Taxonomy and systematics The genus ''Fulica'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name is the Latin word for a Eurasian coot. The name was used by the Swiss naturalist Conrad Gessner in 1555. The type species is the Eurasian coot. A group of coots are referred to as a ''covert'' or ''cover''. Species The genus contains 10 extant species and one which is now extinct. Extinct species Recently extinct species * ''Fulica newtonii'' Milne-Edwards, 1867 – Masc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mallard
The mallard () or wild duck (''Anas platyrhynchos'') is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa, and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males have purple patches on their wings, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is long, of which the body makes up around two-thirds the length. The wingspan is and the bill is long. It is often slightly heavier than most other dabbling ducks, weighing . Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varyin ...

White-throated Dipper
The white-throated dipper (''Cinclus cinclus''), also known as the European dipper or just dipper, is an aquatic passerine bird found in Europe, Middle East, Central Asia and the Indian Subcontinent. The species is divided into several subspecies, based primarily on colour differences, particularly of the pectoral band. The white-throated dipper is Norway's national bird. Taxonomy and systematics The white-throated dipper was described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Sturnus cinclus''. The current genus ''Cinclus'' was introduced by the German naturalist Moritz Balthasar Borkhausen in 1797. The name ''cinclus'' is from the Ancient Greek word that was used to describe small tail-wagging birds that resided near water. Of the five species now placed in the genus, a molecular genetic study has shown that the white-throated dipper is most closely related to the other Eurasian species, the ...

Crossbill
The crossbill is a genus, ''Loxia'', of birds in the finch family (Fringillidae), with six species. These birds are characterised by the mandibles with crossed tips, which gives the group its English name. Adult males tend to be red or orange in colour, and females green or yellow, but there is much variation. Crossbills are specialist feeders on conifer cones, and the unusual bill shape is an adaptation which enables them to extract seeds from cones. These birds are typically found in higher northern hemisphere latitudes, where their food sources grow. They irrupt out of the breeding range when the cone crop fails. Crossbills breed very early in the year, often in winter months, to take advantage of maximum cone supplies. Systematics and evolution The genus ''Loxia'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of his ''Systema Naturae''. The name is from the Ancient Greek , "crosswise". The Swiss naturalist Conrad Gessner had used the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ochropacha Duplaris
''Ochropacha'' is a monotypic moth genus in the family Drepanidae. The genus was first described by Hans Daniel Johan Wallengren in 1871. Its single species, ''Ochropacha duplaris'', the common lutestring, was first described by Carl Linnaeus in 1761. It is found in China (Jilin), Russia, Japan, the Korean Peninsula and from Central Asia to Europe. The wingspan is 27–32 mm. It is similar to '' Tetheella fluctuosa'' but the forewings with the whitish lines usually less distinct, the central band usually dark-striated towards edges, two black discal dots transversely placed, no praesubterminal dash and a dark fuscous oblique apical dash. The larva is pale dull greenish, deeper dorsally; dorsal line darker ; subdorsal broad, dull olive-green ; lateral line, yellowish ; dots black ; head reddish.Meyrick, E., 1895 ''A Handbook of British Lepidoptera'' MacMillan, Londopdf Keys and description The moth flies from June to August depending on the location.

Eulithis Populata
''Eulithis populata'', the northern spinach, is a moth of the genus '' Eulithis'' in the family Geometridae. Etymology The species name ''populata'' derives fron the Latin word ''populus'', meaning poplar, as a food plant for the caterpillar. Distribution and habitat ''Eulithis populata'' is a Holarctic species found in North America, Europe, the Caucasus, Transcaucasia, the Urals, Siberia, Russian Far East, and North Mongolia. These moths usually inhabits blueberry and mixed forests, peat moorland, wetlands and grassland. The altitude distribution reaches up to 2500 meters in the Alps and up to 2300 meters in the Pyrenees. Description The wingspan is 25–32 mm. The ground colour of the forewings is yellow (varying in ground colour from a straw yellow to orange-brown or dark brown). There is a brown central band and a brown basal patch. There is a ''W'' shaped projection on the cross band. Adult caterpillars are extraordinarily variable in colour and have a whitish, ...

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSI ...
