Podiceps Cristatus 2 - Lake Dulverton
''Podiceps'' is a genus of birds in the grebe family. The genus name comes from Latin ''podicis'', "rear-end" and ''ped'', "foot", and is a reference to the placement of a grebe's legs towards the rear of its body. It has representatives breeding in Europe, Asia, North, and South America. Most northern hemisphere species migrate in winter to the coast or warmer climates. They breed in vegetated areas of freshwater lakes, nesting on the water's edge, since their legs are set too far back for easy walking. Usually two eggs are laid, and the striped young may be carried on the adult's back. All the genus are excellent swimmers and divers, and pursue their fish prey underwater. Adults have striking breeding plumage, with no difference between the sexes. In winter, the plumage is subdued whites and greys. Systematics The genus ''Podiceps'' was erected by the English naturalist John Latham in 1787. The type species was subsequently designated as the great crested grebe (''Podice ...

Early Oligocene
The Rupelian is, in the geologic timescale, the older of two ages or the lower of two stages of the Oligocene Epoch/Series. It spans the time between . It is preceded by the Priabonian Stage (part of the Eocene) and is followed by the Chattian Stage. Name The stage is named after the small river Rupel in Belgium, a tributary to the Scheldt. The Belgian Rupel Group derives its name from the same source. The name Rupelian was introduced in scientific literature by Belgian geologist André Hubert Dumont in 1850. The separation between the group and the stage was made in the second half of the 20th century, when stratigraphers saw the need to distinguish between lithostratigraphic and chronostratigraphic names. Stratigraphic definition The base of the Rupelian Stage (which is also the base of the Oligocene Series) is at the extinction of the foraminiferan genus ''Hantkenina''. An official GSSP for the base of the Rupelian has been assigned in 1992 (Massignano, Italy). The transi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helm Identification Guides
The ''Helm Identification Guides'' are a series of books that identify groups of birds. The series include two types of guides, those that are: * Taxonomic, dealing with a particular family of birds on a worldwide scale—most early Helm Guides were this type, as well as many more-recent ones, although some later books deal with identification of such groups on a regional scale only (e.g., ''The Gulls Guide,'' which covers only species in Europe, Asia, and North America) * Geographic, including all bird species in an area (e.g., ''The Birds of the West Indies'') Early volumes were sometimes published under the Croom Helm or Christopher Helm imprints. In addition, a parallel set of guides, very similar in design, was published by Pica Press in the 1990s (marked ''Pica'' in the list below); Pica was later absorbed into A & C Black (now part of Bloomsbury Publishing Plc), and all guides are now marketed as a single series. Several of the books have won the British Birds ''Bird B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podiceps Nigricollis (Marek Szczepanek)2
The black-necked grebe or eared grebe (''Podiceps nigricollis'') is a member of the grebe family of water birds. It was described in 1831 by Christian Ludwig Brehm. There are currently three accepted subspecies, including the nominate subspecies. Its breeding plumage features a distinctive ochre-coloured plumage which extends behind its eye and over its ear coverts. The rest of the upper parts, including the head, neck, and breast, are coloured black to blackish brown. The flanks are tawny rufous to maroon-chestnut, and the abdomen is white. When in its non-breeding plumage, this bird has greyish-black upper parts, including the top of the head and a vertical stripe on the back of the neck. The flanks are also greyish-black. The rest of the body is a white or whitish colour. The juvenile has more brown in its darker areas. The subspecies ''californicus'' can be distinguished from the nominate by the former's usually longer bill. The other subspecies, ''P. n. gurneyi'', can be dif ...

Great Grebe
The great grebe (''Podiceps major'') is the largest species of grebe in the world. A disjunct population exists in northwestern Peru, while the main distribution is from extreme southeastern Brazil to Patagonia and central Chile. The population from southern Chile is considered a separate subspecies, ''P. m. navasi''. Taxonomy The great grebe was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1781 in his ''Histoire Naturelle des Oiseaux''. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Naturelle'' which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name ''Colymbus major'' in his catalogue of the ''Planches Enluminées''. Buffon mistakenly believed that his specimen had come from Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Red-necked Grebe
The red-necked grebe (''Podiceps grisegena'') is a migratory aquatic bird found in the temperate regions of the northern hemisphere. Its wintering habitat is largely restricted to calm waters just beyond the waves around ocean coasts, although some birds may winter on large lakes. Grebes prefer shallow bodies of fresh water such as lakes, marshes or fish-ponds as breeding sites. The red-necked grebe is a nondescript dusky-grey bird in winter. During the breeding season, it acquires the distinctive red neck plumage, black cap and contrasting pale grey face from which its name was derived. It also has an elaborate courtship display and a variety of loud mating calls. Once paired, it builds a nest from water plants on top of floating vegetation in a shallow lake or bog. Like all grebes, the Red-necked is a good swimmer, a particularly swift diver, and responds to danger by diving rather than flying. The feet are positioned far back on the body, near the tail, which makes the bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hooded Grebe
The hooded grebe (''Podiceps gallardoi''), is a medium-sized grebe found in the southern region of Argentina. It grows to about in length, and is black and white in color. It is found in isolated lakes in the most remote parts of Patagonia and spends winters along the coast of the same region. In 2012 IUCN uplisted the species from Endangered to Critically Endangered. Ecology During the breeding season the hooded grebe is found on basaltic lakes in the Patagonian steppes at elevations of 500–1,200 m.Chebez, Juan Carlos. Los que se van: especies argentinas en peligro. No. 596 (822) CHE. 1999. Both saline and bitter salt lakes are used by non breeding flocks and some birds which winter on the coast of Argentina. The grebe requires aquatic vegetation in its breeding lakes (primarily ''Myriophyllum elatinoides'') which it uses to build its nest. The vegetation is also the habitat of the aquatic invertebrates on which the hooded grebe feeds. For example, in the week after hatching ...

Great Crested Grebe
The great crested grebe (''Podiceps cristatus'') is a member of the grebe family of water birds noted for its elaborate mating display. Taxonomy The great crested grebe was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Colymbus cristatus''. The great crested grebe is now the type species of the genus ''Podiceps'' that was erected by the English naturalist John Latham in 1787. The type locality is Sweden. The scientific name comes from Latin: the genus name ''Podiceps'' is from , "vent" and , "foot", and is a reference to the placement of a grebe's legs towards the rear of its body; the species name, ''cristatus'', means "crested". Three subspecies are recognised: * ''P. c. cristatus'' (Linnaeus, 1758) – Eurasia * ''P. c. infuscatus'' Salvadori, 1884 – Africa * ''P. c. australis'' Gould, 1844 – Australia, Tasmania, South Island of New Zealand Description The great creste ...

Horned Grebe
The horned grebe or Slavonian grebe (''Podiceps auritus'') is a relatively small waterbird in the family Podicipedidae. There are two known subspecies: ''P. a. auritus'', which breeds in the Palearctic, and ''P. a. cornutus'', which breeds in North America. The Eurasian subspecies is distributed over most of northern Europe and the Palearctic, breeding from Greenland to western China. The North American subspecies spans most of Canada and some of the United States. The species got its name from large patches of yellowish feathers located behind the eyes, called "horns", that the birds can raise and lower at will. Description Horned grebes can be easily recognised by its red-and-black alternate (breeding) plumage, its black-and-white basic (non-breeding) plumage, and its characteristic "horns". It is 31–38 cm long, has a wingspan 55–74 cm wide and weighs 300–570 g. It has a moderately long neck, flat forehead and a rear crown of black feathers. Its beak ...
