Ashleworth Ham
Ashleworth Ham () is a biological Site of Special Scientific Interest. It is a large area of grassland on the Severn floodplain, north of Ashleworth in Gloucestershire, England. It is registered as a Site of Special Scientific Interest and was notified in 1974 and renotified in 1985. Ashleworth Ham received this designation because it is one of three sites in the Severn Vale where migratory waterfowl winter. The site has three units of assessment and is part managed as a nature reserve by the Gloucestershire Wildlife Trust. The nature reserve is unit 1 () and is a area. Unit 2 () is a site and unit 3 () is a site, and are areas to the east of the nature reserve. The site is fen, marsh, swamp lowland, open water ditches, neutral grassland and hedges divide many of the fields. Access to the reserve is prohibited in winter, but the birds may be viewed from hides in Meerend Thicket. The Thicket is a steep wooded bank and indicates the former much higher boundary of the Sever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, i ...

Bewick's Swan
The tundra swan (''Cygnus columbianus'') is a small swan of the Holarctic. The two taxa within it are usually regarded as conspecific, but are also sometimes split into two species: Bewick's swan (''Cygnus bewickii'') of the Palaearctic and the whistling swan (''C. columbianus'') proper of the Nearctic. Birds from eastern Russia (roughly east of the Taymyr Peninsula) are sometimes separated as the subspecies ''C. c. jankowskii'', but this is not widely accepted as distinct, with most authors including them in ''C. c. bewickii''. Tundra swans are sometimes separated in the subgenus ''Olor'' together with the other Arctic swan species. Bewick's swan was named in 1830 by William Yarrell after the engraver Thomas Bewick, who specialised in illustrations of birds and animals. ''Cygnus'' is the Latin for "swan", and '' columbianus'' comes from the Columbia River, the type locality. Description ''C. columbianus'' is the smallest of the Holarctic swans, at in length, in wingspan and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenshank
The common greenshank (''Tringa nebularia'') is a wader in the large family Scolopacidae, the typical waders. 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 ''nebularia'' is from Latin ''nebula'' "mist". Like the Norwegian ''Skoddefoll'', this refers to the greenshank's damp marshy habitat. Relatives Its closest relative is the greater yellowlegs, which together with the spotted redshank form a close-knit group. Among them, these three species show all the basic leg and foot colours found in the shanks, demonstrating that this character is paraphyletic. They are also the largest shanks apart from the willet, which is altogether more robustly built. The greater yellowlegs and the common greenshank share a coarse, dark, and fairly crisp breast pattern as well as much black on the shoulders and back in ...

Green Sandpiper
The green sandpiper (''Tringa ochropus'') is a small wader (shorebird) of the Old World. The green sandpiper represents an ancient lineage of the genus ''Tringa''; its only close living relative is the solitary sandpiper (''T. solitaria''). They both have brown wings with little light dots and a delicate but contrasting neck and chest pattern. In addition, both species nest in trees, unlike most other scolopacids. Given its basal position in ''Tringa'', it is fairly unsurprising that suspected cases of hybridisation between this species and the common sandpiper (''A. hypoleucos'') of the sister genus ''Actitis'' have been reported. Taxonomy The green sandpiper was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the current binomial name ''Tringa ochropus''. 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 ...

Eurasian Whimbrel
The Eurasian whimbrel or common whimbrel (''Numenius phaeopus'') is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic Asia and Europe as far south as Scotland. This species and the Hudsonian whimbrel have recently been split, although some taxonomic authorities still consider them to be conspecific. Taxonomy The Eurasian whimbrel was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Scolopax phaeopus''. It is now placed with the curlews in the genus '' Numenius'' that was introduced by the French ornithologist Mathurin Jacques Brisson in 1760. The genus name ''Numenius'' is from Ancient Greek ''noumenios'', a bird mentioned by Hesychius. It is associated with the curlews because it appears to be derived from ''neos'', "new" and ''mene'' "moon", referring to the crescent-shaped bill. The specific epithet ''phaeopus' ...

Reed Bunting
The common reed bunting (''Emberiza schoeniclus'') is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae. The genus name ''Emberiza'' is from Old German ''Embritz'', a bunting. The specific ''schoeniclus'' is from Ancient Greek ''skhoiniklos'', a now unknown waterside bird. It breeds across Europe and much of the Palearctic. Most birds migrate south in winter, but those in the milder south and west of the range are resident. It is common in reedbeds and also breeds in drier open areas such as moorland and cultivation. For example, it is a component of the purple moor grass and rush pastures, a type of Biodiversity Action Plan habitat in the UK. It occurs on poorly drained neutral and acidic soils of the lowlands and upland fringe. Taxonomy The common reed bunting was described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name '' ...

Western Yellow Wagtail
The western yellow wagtail (''Motacilla flava'') is a small passerine in the wagtail family Motacillidae, which also includes the pipits and longclaws. This species breeds in much of temperate Europe and Asia. It is resident in the milder parts of its range, such as western Europe, but northern and eastern populations migrate to Africa and south Asia. It is a slender 15–16 cm long bird, with the characteristic long, constantly wagging tail of its genus. It is the shortest tailed of the European wagtails. The breeding adult male is basically olive above and yellow below. In other plumages, the yellow may be diluted by white. The heads of breeding males come in a variety of colours and patterns depending on subspecies. The call is a high-pitched ''jeet''. This insectivorous bird inhabits open country near water, such as wet meadows. It nests in tussocks, laying 4–8 speckled eggs. Systematics ''Motacilla'' is the Latin name for the wagtail; although actually a di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedge Warbler
The sedge warbler (''Acrocephalus schoenobaenus'') is an Old World warbler in the genus '' Acrocephalus''. It is a medium-sized warbler with a brown, streaked back and wings and a distinct pale supercilium. Sedge warblers are migratory, crossing the Sahara to get from their European and Asian breeding grounds to spend winter in Africa. The male's song is composed of random chattering phrases and can include mimicry of other species. The sedge warbler is mostly insectivorous. Taxonomy The sedge warbler was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Motacilla schoenobaenus''. The species is now placed in the genus '' Acrocephalus'' that was introduced in 1811 by Johann Andreas Naumann and his son Johann Friedrich Naumann. British ornithologists did not distinguish the species from the Eurasian reed warbler until the 18th century. The genus name ''Acrocephalus'' is from Ancient Gree ...

Common Grasshopper Warbler
The common grasshopper warbler (''Locustella naevia'') is a species of Old World warbler in the grass warbler genus ''Locustella''. It breeds across much of temperate Europe and the western Palearctic. It is migratory, wintering in north and west Africa. This small passerine bird is found in short dense vegetation, often close to water. It is a medium-sized warbler about long. The adult has a streaked brown back and whitish grey underparts which are unstreaked except on the undertail coverts. The sexes are identical, as with most warblers, but young birds are yellower below. Like most warblers, it is insectivorous. Four to seven eggs are laid in a nest on or near the ground in thick vegetation or in a tussock of grass. This is a species which skulks in the undergrowth, creeping through bushes and low foliage, and which is very difficult to see except sometimes when singing from a prominent position. The song, which gives this species its name, is a monotonous mechanical in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Redstart
The common redstart (''Phoenicurus phoenicurus''), or often simply redstart, is a small passerine bird in the genus ''Phoenicurus''. Like its relatives, it was formerly classed as a member of the thrush family, (Turdidae), but is now known to be an Old World flycatcher (family Muscicapidae). Taxonomy and systematics The first formal description of the common redstart was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Motacilla phoenicurus''. The genus ''Phoenicurus'' was introduced by the English naturalist Thomas Forster in 1817. The genus and species name ''phoenicurus'' is from Ancient Greek ''phoinix'', "red", and ''-ouros'' -"tailed". Two subspecies are accepted. The nominate ''P. p. phoenicurus'' is found all over Europe and reaches into Siberia. To the southeast, subspecies ''P. p. samamisicus'' is found from the Crimean Peninsula through Turkey, the Middle East, and into Central Asia. It is sli ...

Common Redshank
The common redshank or simply redshank (''Tringa totanus'') is a Eurasian wader in the large family Scolopacidae. Taxonomy The common redshank was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Scolopax totanus''. It is now placed with twelve other species in the genus ''Tringa'' that Linnaeus had introduced in 1758. The genus name ''Tringa'' is the New Latin name given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1603 based on Ancient Greek ''trungas'', a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific ''totanus'' is from , the Italian name for this bird. Six subspecies are recognised: * ''T. t. robusta'' ( Schiøler, 1919) – breeds in Iceland and the Faroe Islands; non-breeding around the British Isles and west Europe * ''T. t. totanus'' (Linnaeus, 1758) – breeds in west, north Europe to west Siberia; winters in ...

Eurasian Curlew
The Eurasian curlew or common curlew (''Numenius arquata'') is a very large wader in the family Scolopacidae. It is one of the most widespread of the curlews, breeding across temperate Europe and Asia. In Europe, this species is often referred to just as the "curlew", and in Scotland known as the "whaup" in Scots. Taxonomy The Eurasian curlew was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Scolopax arquata''. It is now placed with eight other curlews in the genus '' Numenius'' that was introduced by the French ornithologist Mathurin Jacques Brisson in 1760. The genus name ''Numenius'' is from Ancient Greek νουμήνιος, ''noumēnios'', a bird mentioned by Hesychius. It is associated with the curlew because it appears to be derived from ''neos'', "new" and ''mene'' "moon", referring to the crescent-shaped bill.
