Puffinus
''Puffinus'' is a genus of seabirds in the order Procellariiformes that contains about 20 small to medium-sized shearwaters. Two other shearwater genera are named: '' Calonectris'', which comprises three or four large shearwaters, and '' Ardenna'' with another seven species (formerly often included within ''Puffinus''). The taxonomy of this group is the cause of much debate, and the number of recognised species varies with the source. The species in this group are long-winged birds, dark brown or black above, and white to dark brown below. They are pelagic outside the breeding season. They are most common in temperate and cold waters. These tubenose birds fly with stiff wings, and use a shearing flight technique to move across wave fronts with the minimum of active flight. Some small species, such as the Manx shearwater, are cruciform in flight, with their long wings held directly out from their bodies. Many are long-distance migrants, perhaps most spectacularly the sooty an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shearwater
Shearwaters are medium-sized long-winged seabirds in the petrel family Procellariidae. They have a global marine distribution, but are most common in temperate and cold waters, and are pelagic outside the breeding season. Description These tubenose birds fly with stiff wings and use a "shearing" flight technique (flying very close to the water and seemingly cutting or "shearing" the tips of waves) to move across wave fronts with the minimum of active flight. This technique gives the group its English name. Some small species like the Manx shearwater are cruciform in flight, with their long wings held directly out from their bodies. Behaviour Movements Many shearwaters are long-distance migrants, perhaps most spectacularly sooty shearwaters, which cover distances in excess of from their breeding colonies on the Falkland Islands (52°S 60°W) to as far as 70° north latitude in the North Atlantic Ocean off northern Norway, and around New Zealand to as far as 60° north latitude i ...

Manx Shearwater
The Manx shearwater (''Puffinus puffinus'') is a medium-sized shearwater in the seabird family Procellariidae. The scientific name of this species records a name shift: Manx shearwaters were called Manks puffins in the 17th century. Puffin is an Anglo-Norman language, Anglo-Norman word (Middle English ''pophyn'') for the Curing (food preservation), cured carcasses of nestling shearwaters. The Atlantic puffin acquired the name much later, possibly because of its similar nesting habits. Taxonomy The shearwaters form part of the family Procellariidae, a widespread group containing nearly 100 species of medium to large seabirds. They have long, narrow wings and the characteristic “tube nose”. Although it was considered a monotypic species, recently an endemic subspecies for the Canary Islands has been proposed ''P. puffinus canariensis''. The large genus ''Puffinus'' includes several species formerly considered to be subspecies of the Manx shearwater, including the yelkouan shea ...

Fluttering Shearwater
The fluttering shearwater (''Puffinus gavia'') is a species of seabird in the family Procellariidae. It is endemic to New Zealand and migrates to Australia and the Solomon Islands. Its natural habitats are open seas and rocky shores. It has been known as Forster's shearwater in the past. Description This is a medium to small-sized shearwater with a dark-brown-and-white body. The upper parts, including neck, wings and tail, are uniformly dark brown. The face and neck have a grey-brown colour gradually fading into white below the eye. The under body, from chin to the under-tail, is white except for a dark thigh patch that can be seen in flight. The bottom wing is commonly white while the axillary area is covered in grey-brown fur. Under light conditions, the appearance is different. The fluttering shearwater has pinkish-brown legs and feet with dark webs, and the feet extend beyond the tail in flight. The bill is long and thin with dark colour. The tail is fan-shaped and short in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-tailed Shearwater
The short-tailed shearwater or slender-billed shearwater (''Ardenna tenuirostris''; formerly ''Puffinus tenuirostris''), also called yolla or moonbird, and commonly known as the muttonbird in Australia, is the most abundant seabird species in Australian waters, and is one of the few Australian native birds in which the chicks are muttonbirding, commercially harvested. It is a migratory species that breeds mainly on small islands in Bass Strait and Tasmania and migrates to the Northern Hemisphere for the boreal summer. Taxonomy This shearwater appears to be related to the sooty shearwater, sooty and great shearwaters, which are also blunt-tailed, black-billed species, but its precise relationships are obscure (Austin, 1996; Austin ''et al.'', 2004). These are among the larger species of shearwater, which have been moved to a separate genus, ''Ardenna'' based on a phylogenetic analysis of mitochondrial DNA (Penhallurick & Wink, 2004). Ecology Each parent feeds the single chick fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ardenna
''Ardenna'' is a genus of seabirds in the family Procellariidae. These medium-sized to large shearwater species were formerly included in the genus ''Puffinus''. Taxonomy A phylogenetic analysis using mitochondrial DNA published in 2004 found that ''Puffinus'' contained two distinct clades and was polyphyletic, with ''Puffinus'' more closely related to ''Calonectris'' than to ''Ardenna''. To create monophyletic genera a group of species were moved into ''Ardenna'', a genus that had been introduced in 1853 by Ludwig Reichenbach with the great shearwater as the type species. Reichenbach cites the Italian naturalist Ulisse Aldrovandi who in 1603 used the spelling "Artenna" for a seabird. Recent genomic studies have validated the phylogenetic distinction between ''Ardenna'' and ''Puffinus'', though this study finding ''Ardenna'' rather than ''Puffinus'' being closer to ''Calonectris''. Species Extant The genus contains seven extant species as shown below: Extinct The genus contains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sooty Shearwater
The sooty shearwater (''Ardenna grisea'') is a medium-large shearwater in the seabird family Procellariidae. In New Zealand, it is also known by its Māori language, Māori name , and is harvested by Māori people for muttonbirding, muttonbird, like its relatives the wedge-tailed shearwater (''A. pacificus'') and the Australian short-tailed shearwater (''A. tenuirostris''). Taxonomy The sooty shearwater was species description, formally described in 1789 by the German naturalist Johann Friedrich Gmelin under the binomial name ''Procellaria grisea''. The shearwater had been briefly described in 1777 by James Cook in the account of his Second voyage of James Cook, second voyage to the Pacific, but without a valid scientific name; and also in 1785 the English ornithologist John Latham (ornithologist), John Latham had described a museum specimen, again without giving it a scientific name. The sooty shearwater is now placed in the genus ''Ardenna'', that was described in 1853 by Ludwig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seabird
Seabirds (also known as marine birds) are birds that are adaptation, adapted to life within the marine ecosystem, marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding ecological niche, niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous geological period, period, while modern seabird families emerged in the Paleogene. Seabirds generally live longer, Reproduction, breed later and have fewer young than other birds, but they invest a great deal of time in their young. Most species nest in Bird colony, colonies, varying in size from a few dozen birds to millions. Many species are famous for undertaking long annual bird migration, migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even on each other. Seabirds can be highly pelagic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calonectris
''Calonectris'' is a genus of seabirds. The genus name comes from Ancient Greek ''kalos'', "good" and ''nectris'', "swimmer". The genus comprises four large shearwaters. There are two other shearwater genera, ''Puffinus'', which comprises 21 small to medium-sized shearwaters, and ''Ardenna'' with 7 larger species. The species in this group are long-winged birds, dark brown or grey-brown above, and mainly white below. They are pelagic outside the breeding season. They are most common in temperate and cold waters. Like most other tubenose birds, they use a shearing flight technique to move across wave fronts with the minimum of active flight, but fly with a more relaxed, fluid, flexible wing action than the other shearwaters in ''Puffinus'' and ''Ardenna''. Svensson, L., Mullarney, K., & Zetterström, D. (2022) ''Collins Bird Guide'', ed. 3. , pages 68-69 ''Calonectris'' shearwaters are long-distance migrants.

Procellariiformes
Procellariiformes is an order (biology), order of seabirds that comprises four family (biology), families: the albatrosses, the Procellariidae, petrels and shearwaters, and two families of storm petrels. Formerly called Tubinares and still called tubenoses in English, procellariiforms are often referred to collectively as the petrels, a term that has been applied to all members of the order,Warham, J. (1996). ''The Behaviour, Population, Biology and Physiology of the Petrels''. London: Academic Press, or more commonly all the families except the albatrosses.Brooke, 2004. They are almost exclusively pelagic (feeding in the open ocean), and have a cosmopolitan distribution across the world's oceans, with the highest species diversity, diversity being around New Zealand. Procellariiforms are seabird colony, colonial, mostly nesting on remote, predator-free islands. The larger species nest on the surface, while most smaller species nest in natural cavities and burrows. They exhibit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Migration
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of Procellariiformes, tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...
