Synthliboramphus
''Synthliboramphus'' is a small genus of seabirds in the auk family from the North Pacific. The genus name ''Synthliboramphus'' is from Ancient Greek ''sunthlibo'', "to compress", and ''rhamphos'', "bill". The English name "Murrelet" is a diminutive of "murre", a word of uncertain origins, but which may imitate the call of the common guillemot. Taxonomy The genus ''Synthliboramphus'' was introduced in 1837 by the German born naturalist Johann Friedrich von Brandt. The type genus was subsequently designated by George Robert Gray as the ancient murrelet. The genus name combines Ancient Greek ''sunthlibō'' meaning "to compress" with ''rhamphos'' meaning "bill". The genus contains five species: The first two species were formally considered conspecific, and are sometimes separated in the genus ''Endomychura''. Fossil remains of two prehistoric species are known: an undescribed ''Synthliboramphus'' sp. from the Late Miocene or Early Pliocene (c. 5 mya) of Cedros Island, M ...

Japanese Murrelet
The Japanese murrelet or crested murrelet (''Synthliboramphus wumizusume'') is a small seabird in the auk family that occurs along the remote rocky coasts and in the offshore waters of Japan, and may also be found after the breeding season as far as Sakhalin to the north and in particular off South Korea. With a small and declining population, estimated as of 2017 to total 2,500–10,000 individuals, it is the rarest alcid, and the most at risk of extinction. Taxonomy The Japanese murrelet is a monotypic species first described by Coenraad Temminck, as ''Uria wumizusume'', in the text accompanying an 1836 '' livraison'' in the ongoing series ''Nouveau recueil de planches coloriées d’oiseaux''. The following year, Johann Friedrich von Brandt erected the genus ''Brachyramphus'' and subgenus ''Synthliboramphus'', transferring to it the Japanese murrelet, to which he gave the new specific name ''temminckii''. ''Synthliboramphus'' has since been raised to generic rank, the specif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guadalupe Murrelet
The Guadalupe murrelet (''Synthliboramphus hypoleucus'') or Xantus' Murrelet is a small seabird found in the California Current system in the Pacific Ocean. This auk breeds on islands off California and Mexico. It is threatened by predators introduced to its breeding colonies and by oil spills. This species together with the Scripps's murrelet were considered conspecific and were classified under ''S. hypoleucus''; known collectively as Xantus's murrelet until 2012. Enough evidence was collected to consider both species distinct based on a lack of evidence of interbreeding where the two species nest together on the San Benito Islands, differences in facial pattern and bill shape, vocalizations and genetics. Description and range This species is a small black and white auk with a small head and thin sharp bill. It resembles the closely related Scripps's and Craveri's murrelet, with which it shares the distinction of being the most southerly living of all the auk species. It b ...

Craveri's Murrelet
Craveri's murrelet (''Synthliboramphus craveri'') is a small seabird which breeds on offshore islands in both the Pacific Ocean and the Gulf of California off the Baja peninsula of Mexico. It also wanders fairly regularly as far as central California in the US, primarily during post-breeding dispersal. It is threatened by predators introduced to its breeding colonies, by oil spills, and by tanker traffic. Increasing tourism development and commercial fishing fleets also further threaten the species. With an estimated population of 6,000-10,000 breeding pairs, its population is listed as vulnerable. Description and range The Craveri's murrelet is a small black and white auk with a small head and thin sharp bill. It resembles the closely related Scripps's murrelet, with which it shares the distinction of being the most southerly living of all the auk species. The Craveri's murrelet has a partial neck collar (Scripps's has none), and dusky underwings (Scripps's has white un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcidae - Synthliboramphus Craveri
An auk or alcid is a bird of the family Alcidae in the order Charadriiformes. The alcid family includes the murres, guillemots, auklets, puffins, and murrelets. The word "auk" is derived from Icelandic ''álka'', from Old Norse ''alka'' (auk), from Proto-Germanic *''alkǭ'' (sea-bird, auk). The family contains 25 extant or recently extinct species that are divided into 11 genera. Apart from the extinct great auk, all auks can fly, and are excellent swimmers (appearing to "fly") and divers, but their walking appears clumsy. Several species have different English names in Europe and North America. The two species known as murres in North America are called guillemots in Europe, and the species called little auk in Europe is referred to as dovekie in North America. Description Auks are superficially similar to penguins, having black-and-white colours, upright posture, and some of their habits. Nevertheless, they are not closely related to penguins, but rather are believed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scripps's Murrelet
Scripps's murrelet (''Synthliboramphus scrippsi'') is a small seabird found in the California Current system in the Pacific Ocean. This auk breeds on islands off California and Mexico. It is threatened by predators introduced to its breeding colonies and by oil spills. This species and the Guadalupe murrelet were considered conspecific and were known collectively as Xantus's murrelet until 2012. The two species are now considered distinct based on a lack of evidence of interbreeding at a shared nesting colony on the San Benito Islands, differences in facial pattern and bill shape, and differences in vocalizations and genetics. Description and range This species is a small black and white auk with a small head and thin sharp bill. It resembles the closely related Craveri's murrelet, with which it shares the distinction of being the most southerly living of all the auk species. It breeds on islands in the Channel Islands of California, the largest colonies being on the Coronado I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Murrelet
The ancient murrelet (') is a bird in the auk family. The English term "murrelet" is a diminutive of "murre", a word of uncertain origins, but which may imitate the call of the common guillemot. Ancient murrelets are called "ancient" because they have grey on the back like a shawl, as worn by the elderly.Attenborough, D. 1998. ''The Life of Birds''. BBC Books. . Taxonomy The ancient murrelet was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the auks in the genus '' Alca'' and coined the binomial name ''Alca antiqua''. Gmelin based his description on the "ancient auk" that had been described in 1785 by both the English ornithologist John Latham and the Welsh naturalist Thomas Pennant. Both authors mention a specimen in the Leverian Museum and give the location as the west of North America, the Kuril Islands and the Kamchatka Peninsula. The ancient murrelet ...

Common Guillemot
The common murre or common guillemot (''Uria aalge'') is a large auk. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands. Common murres have fast direct flight but are not very agile. They are more maneuverable underwater, typically diving to depths of . Depths of up to have been recorded. Common murres breed in colonies at high densities. Nesting pairs may be in bodily contact with their neighbours. They make no nest; their single egg is incubated on a bare rock ledge on a cliff face. Eggs hatch after ~30 days incubation. The chick is born downy and can regulate its body temperature after 10 days. Some 20 days after hatching the chick leaves its nesting ledge and heads for the sea, unable to fly, but gliding for some distance with fluttering wings, accompanied by its male parent. Male guillemots spend more time di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cedros Island
Cedros Island (''Isla de Cedros'', "island of cedars" in Spanish) is an island in the Pacific Ocean belonging to the state of Baja California, Mexico. The dry and rocky island had a population of 1,350 in 2005 and has an area of which includes the area of several small nearby islands. Cedros Island is mountainous, reaching a maximum elevation of . The economy is based on commercial fishing and salt production. Cedros has a distinctive flora and the traces of some of the earliest human beings in the New World. The ocean around the island is popular with sport fishermen. There was human presence of the island already about 11,000 years ago. The American Indian inhabitants when the island was first visited by Spanish explorers in the 16th century called it Huamalgua, the "Island of Fogs." The Indian inhabitants have been given the name Huamalgueños by modern day scholars. They were relocated to the mainland of Baja California by Jesuit missionaries in 1732 and ceased to exis ...
