Cepphus
''Cepphus'' is a genus of seabirds in the auk family also referred to as true guillemots or, in North America, simply as guillemots. The genus name ''Cepphus'' is from Ancient Greek ''kepphos'',. a pale waterbird mentioned by Greek authors including Aristotle. The English word "guillemot" is from French ''guillemot'' probably derived from ''Guillaume'', "William". "Murre" is of uncertain origins, but may imitate the call of the common guillemot. These are medium-sized birds with mainly black plumage in the breeding season, thin dark bills and red legs and feet. Two species have white wing patches, the third has white facial “spectacles”. They are much paler in winter plumage, mottled above and white below. The breeding habitat is rocky shores and islands on the coasts of the northern Atlantic and Pacific Oceans. They usually lay their eggs in rocky sites near water. These birds may overwinter in their breeding areas, moving to open waters if necessary, but usually not migr ...

Pigeon Guillemot
The pigeon guillemot (''Cepphus columba'') () is a species of bird in the auk family, Alcidae. One of three species in the genus ''Cepphus'', it is most closely related to the spectacled guillemot. There are five subspecies of the pigeon guillemot; all subspecies, when in , are dark brown with a black iridescent sheen and a distinctive wing patch broken by a brown-black wedge. Its has mottled grey and black and white . The long bill is black, as are the claws. The legs, feet, and inside of the mouth are red. It closely resembles the black guillemot, which is slightly smaller and lacks the dark wing wedge present in the pigeon guillemot. This seabird is found on North Pacific coastal waters, from Siberia through Alaska to California. The pigeon guillemot breeds and sometimes roosts on rocky shores, cliffs, and islands close to shallow water. In the winter, some birds move slightly south in the northernmost part of their range in response to advancing ice and migrate slightl ...

Guillemot
Guillemot is the common name for several species of seabird in the Alcidae or auk family (part of the order Charadriiformes). In British use, the term comprises two genera: ''Uria'' and ''Cepphus''. In North America the ''Uria'' species are called murres and only the ''Cepphus'' species are called "guillemots". This word of French origin derives from a form of the name William, cf. french: Guillaume. The two living species of ''Uria'', together with the razorbill, dovekie, and the extinct great auk, make up the tribe Alcini. They have distinctly white bellies, thicker and longer bills than ''Cepphus'', and form very dense colonies on cliffs during the reproductive season. Guillemot eggs are large (around 11% of female weightGaston & Jones (1998)), pyriform in shape, and colourful, making them attractive targets for egg collectors. The three living species of ''Cepphus'' form a tribe of their own: Cepphini. They are smaller than the ''Uria'' species and have black bellies, ro ...

Black Guillemot
The black guillemot or tystie (''Cepphus grylle'') is a medium-sized seabird of the Alcidae family, native throughout northern Atlantic coasts and eastern North American coasts. It is resident in much of its range, but large populations from the high arctic migrate southwards in winter. The bird can be seen in and around its breeding habitat of rocky shores, cliffs and islands in single or smalls groups of pairs. They feed mainly by diving towards the sea floor feeding on fish, crustaceans or other benthic invertebrates. They are listed on the IUCN red list as a species of least concern. Both sexes have very similar appearances with black plumage and a large white patch on the upper side of their wings in summer. The bill is also black, being rather long and slender, while the feet are coral-red. In winter adult underparts are white and the upperparts are a pale grey with the back and shoulders exhibiting barred light grey and white patterning. The birds breed in solitary pairs o ...

Spectacled Guillemot
The spectacled guillemot or sooty guillemot (''Cepphus carbo'') is a seabird in the auk family. Description This species is about with red legs, black bill, and a blackish iris. The breeding adult spectacled guillemot is distinctive, mostly plumaged dull sooty-black except for conspicuous white "spectacles" on the face In adult non-breeding plumage, the underparts are white, uniformly tipped very pale grey-brown. Transitional birds are like breeding adults, except the underparts are scaled with white. Sexes are alike, but juveniles are separable from adults. There are no subspecies. Range The spectacled guillemot's range is restricted to the northwestern Pacific Ocean: throughout the Sea of Okhotsk and the Kuril Islands in Russia and on the northern island of Hokkaidō in Japan. Its range overlaps with that of the closely related pigeon guillemot The pigeon guillemot (''Cepphus columba'') () is a species of bird in the auk family, Alcidae. One of three species in the gen ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Genera
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bi ...

Pigeon Guillemot At Living Coasts
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on bran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
