Ardenna
''Ardenna'' is a genus of seabirds in the family Procellariidae. These medium-sized 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. 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 Ulisse Aldrovandi (11 September 1522 – 4 May 1605) was an Italian naturalist, the moving force behind Bologna's botanical garden, one of the first in Europe.

Shearwater
Shearwaters are medium-sized long-winged seabirds in the petrel family Procellariidae The family Procellariidae is a group of seabirds that comprises the fulmarine petrels, the gadfly petrels, the diving petrels, the prions, and the shearwaters. This family is part of the bird order Procellariiformes (or tubenoses), which also .... They have a global marine distribution, but are most common in temperate and cold waters, and are pelagic outside the breeding season. Description These Procellariiformes, 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great Shearwater
The great shearwater (''Ardenna gravis'') is a large shearwater in the seabird family Procellariidae. It breeds colonially on rocky islands in the south Atlantic. Outside the breeding season it ranges widely in the Atlantic. Taxonomy The great shearwater was formally described in 1818 by the Irish naturalist Bernard O'Reilly and given the binomial name ''Procellaria gravis''. The great shearwater is now placed in the genus ''Ardenna'' that was introduced in 1853 by Ludwig Reichenbach. The genus name ''Ardenna'' was used to refer to a seabird by Italian naturalist Ulisse Aldrovandi in 1603. The specific epithet ''gravis'' is Latin meaning "heavy" or "weighty". The species is monotypic: no subspecies are recognised. Description This shearwater is 43–51 cm (16.9–20.1 in) in length with a 105–122 cm (3.5–4.0 ft) wingspan. It is identifiable by its size, dark upper parts, and white under parts, with the exception of a brown belly patch and dark shoulder markings. It has ...

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 name , and as muttonbird, like its relatives the wedge-tailed shearwater (''A. pacificus'') and the Australian short-tailed shearwater (''A. tenuirostris''). Taxonomy The sooty shearwater was 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 to the Pacific, and in 1785 the English ornithologist John Latham had described a museum specimen. The sooty shearwater is now placed in the genus ''Ardenna'', that was introduced in 1853 by Ludwig Reichenbach. The genus name ''Ardenna'' was used to refer to a seabird by Italian naturalist Ulisse Aldrovandi in 1603, and the specific epithet ''grisea'' is medieval Latin for "grey". The species is considered to be mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flesh-footed Shearwater
The flesh-footed shearwater (''Ardenna carneipes''; formerly ''Puffinus carneipes'') is a medium-sized shearwater. Its plumage is black. It has pale pinkish feet, and a pale bill with a distinct black tip. Together with the equally light-billed pink-footed shearwater, it forms the ''Hemipuffinus'' group, a superspecies which may or may not have an Atlantic relative in the great shearwater. These large shearwaters are among those that have been separated into the genus ''Ardenna''. Recent genetic analysis indicates evidence of strong divergence between Pacific colonies relative to those in South and Western Australia, thought to be explained by philopatry and differences in foraging strategies during the breeding season. A molecular phylogenetic study published in 2021 found very little genetic difference between the flesh-footed shearwater and the pink-footed shearwater (''Ardenna creatopus''). The authors of the study suggested that these two taxa might be better considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pink-footed Shearwater
The pink-footed shearwater (''Ardenna creatopus'') is a species of seabird. The bird is in length, with a wingspan. It is polymorphic, having both darker- and lighter-phase populations. Together with the equally light-billed flesh-footed shearwater, it forms the ''Hemipuffinus'' group, a superspecies that may or may not have an Atlantic relative in the great shearwater. These are large shearwaters which are among those that could be separated in the genus ''Ardenna''. A molecular phylogenetic study published in 2021 found very little genetic difference between the pink-footed shearwater and the flesh-footed shearwater (''Ardenna carneipes''). The authors of the study suggested that these two taxa might be better considered as conspecific. This species is pelagic, occurring in the Pacific Ocean. It predominantly nests on offshore islands off Chile, i.e. Mocha Island. It is a transequatorial migrant, moving toward subarctic waters of the Pacific after raising its young. It is ...

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 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 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 for 2–3 days and then leaves for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buller's Shearwater
Buller's shearwater (''Ardenna bulleri'') is a Pacific species of seabird in the family Procellariidae; it is also known as the grey-backed shearwater or New Zealand shearwater. A member of the black-billed wedge-tailed ''Thyellodroma'' group, among the larger shearwaters of the genus ''Ardenna'', it forms a superspecies with the wedge-tailed shearwater (''A. pacificus''). Description Adults birds are in length, with a wingspan, and have been recorded to weigh . The upperside of Buller's shearwater is bluish grey. A blackish stripe runs from the tertiary remiges to the primary wing coverts. The primary remiges are blackish, also; the two black areas do not meet at the hand, however; the area between them is a rather light grey, and under bright light may appear almost white. With the bird facing upwards, the pattern gives the impression of a broken black "M", with light grey interspersing areas.Carboneras (1992) The underside is bright white; on the head the upperside's gre ...

Wedge-tailed Shearwater
The wedge-tailed shearwater (''Ardenna pacifica'') is a medium-large shearwater in the seabird family Procellariidae. It is one of the shearwater species that is sometimes referred to as a muttonbird, like the sooty shearwater of New Zealand and the short-tailed shearwater of Australia. It ranges throughout the tropical Pacific and Indian Oceans, roughly between latitudes 35°N and 35°S. It breeds on islands off Japan, on the Islas Revillagigedo, the Hawaiian Islands, the Seychelles, the Northern Mariana Islands, and off Eastern and Western Australia. Taxonomy The wedge-tailed shearwater 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 petrels in the genus ''Procellaria'' and coined the binomial name ''Procellaria pacifica''. Gmelin based his description on the "Pacific petrel" that had been described in 1785 by the English ornithologist John Latham i ...
