Hydrobates Monteiroi
Monteiro's storm petrel (''Hydrobates monteiroi'') is a seabird species from the storm petrel family, Hydrobatidae. The cryptic species was once considered to be conspecific with the band-rumped storm petrel.M. Bolton, A.L. Smith, E. Gomez-Diaz, V.L. Friesen, R. Medeiros, J. Bried, J.L. Roscales & R.W. Furness (2008) "Monteiro's Storm Petrel ''Oceanodroma monteiroi'': a new species from the Azores" ''Ibis'' 150 (4): 717–727 The species is endemic to the Azores. Taxonomy The existence of a separate species was first hinted at by the discovery of two distinct breeding seasons of ''Hydrobates'' storm-petrels in the Azores. Both populations were initially thought to be of band-rumped storm petrels; however, one population breeds during the cool season, and the other during the hot season. A closer study of these two breeding populations found differences in their morphology and moult. Examination of the mtDNA found that the two populations were indeed genetically isolated, ...

Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds and ...

Islet
An islet is a very small, often unnamed island. Most definitions are not precise, but some suggest that an islet has little or no vegetation and cannot support human habitation. It may be made of rock, sand and/or hard coral; may be permanent or tidal (i.e. surfaced reef or seamount); and may exist in the sea, lakes, rivers or any other sizeable bodies of water. Definition As suggested by its origin ''islette'', an Old French diminutive of "isle", use of the term implies small size, but little attention is given to drawing an upper limit on its applicability. The World Landforms website says, "An islet landform is generally considered to be a rock or small island that has little vegetation and cannot sustain human habitation", and further that size may vary from a few square feet to several square miles, with no specific rule pertaining to size. Other terms * Ait (/eɪt/, like eight) or eyot (/aɪ(ə)t, eɪt/), a small island. It is especially used to refer to river i ...

Birds Of The Azores
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. ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Long-eared Owl
The long-eared owl (''Asio otus''), also known as the northern long-eared owlOlsen, P.D. & Marks, J.S. (2019). ''Northern Long-eared Owl (Asio otus)''. In: del Hoyo, J., Elliott, A., Sargatal, J., Christie, D.A. & de Juana, E. (eds.). Handbook of the Birds of the World Alive. Lynx Edicions, Barcelona. or, more informally, as the lesser horned owl or cat owl,Voous, K.H. (1988). ''Owls of the Northern Hemisphere''. The MIT Press, . is a medium-sized species of owl with an extensive breeding range. The scientific name is from Latin. The genus name ''Asio'' is a type of eared owl, and ''otus'' also refers to a small, eared owl. The species breeds in many areas through Europe and the Palearctic, as well as in North America.

Petrel
Petrels are tube-nosed seabirds in the bird order Procellariiformes. Description The common name does not indicate relationship beyond that point, as "petrels" occur in three of the four families within that group (all except the albatross family, Diomedeidae). Having a fossil record that was assumed to extend back at least 60 million years, the Procellariiformes was long considered to be among the older bird groupings, other than the ratites, with presumably distant ties to penguins and loons. However, recent research and fossil finds such as ''Vegavis'' show that the Galliformes (pheasants, grouse and relatives), and Anseriformes (ducks, geese) are still not fully resolved. Known species All the members of the order are exclusively pelagic in distribution—returning to land only to breed. The family Procellariidae is the main radiation of medium-sized true petrels, characterised by united nostrils with medium septum, and a long outer functional primary feather. It is dom ...

Digital Object Identifier
A digital object identifier (DOI) is a persistent identifier or handle used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). DOIs are an implementation of the Handle System; they also fit within the URI system ( Uniform Resource Identifier). They are widely used to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications. DOIs have also been used to identify other types of information resources, such as commercial videos. A DOI aims to resolve to its target, the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL where the object is located. Thus, by being actionable and interoperable, a DOI differs from ISBNs or ISRCs which are identifiers only. The DOI system uses the indecs Content Model for representing metadata. The DOI for a document remains fixed over t ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the A ...

Procellariiformes
Procellariiformes is an order of seabirds that comprises four families: the albatrosses, the 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 diversity being around New Zealand. Procellariiforms are 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 strong philopatry, returning to their natal colony to breed and returning to th ...

Graciosa
Graciosa Island () (literally "graceful" or "enchanting" in Portuguese) is referred to as the ''White Island'', the northernmost of the Central Group of islands in the Azores. The ovular Portuguese island has an area of , a length of and a width of . It is a volcanic island, dominated by a central caldera (the Caldeira) located in the southeast. History In addition to the other islands of the Central Group, Graciosa was explored by Portuguese navigators during the first quarter of the 15th century, although there exist no accounts of the first sighting of the island. May 2, 1450 has frequently been referred to as the date of the island's "discovery", although there exists no documentation to support this date. Paradoxically, it is clear that in 1440, by order of Prince Henry the Navigator, cattle and swine were settled on the island in order to facilitate colonization. Similarly, it is unclear the names of the first settlers to colonize the island, although around 1450 th ...

Praia Islet
Praia Islet ( pt, Ilhéu da Praia; literally, ''Beach Islet'') is a highly vegetated uninhabited islet located approximately away from the town of Praia off the eastern coast of the island of Graciosa in the Portuguese archipelago of the Azores. Along with Baixo Islet to its south, Praia Islet is one of two main breeding places of Monteiro's storm petrel, an endemic marine bird of the Azores. History On 7 February 2022 at 23:30—about half an hour after leaving the Port of Praia da Graciosa—the Portuguese fuel tanker ship ''São Jorge'', which distributes liquid fuel throughout the Azores, ran aground off the coast of Praia Islet, causing severe damage to the ship's hull and propellers. Portos dos Açores, S.A. (the Azorean interisland port authority) stated that the ship's cargo of gasoline and diesel fuel did not leak as a result of the incident. Geography Praia Islet is a basaltic, palagonite islet formed by pyroclastic lava flows during the Graciosa Caldera's las ...

Baixo Islet
Baixo Islet ( pt, Ilhéu de Baixo; ''Lower Islet'' in English), also known locally as ''Ilhéu do Carapacho'' ('' Carapace Islet'') and historically as ''Ilhéu dos Homiziados'' (''Islet of the Fugitives''), is a small uninhabited islet group located off the southeast coast of the island of Graciosa in the Portuguese archipelago of the Azores. Along with Praia Islet to its north, Baixo Islet is one of two main breeding places of Monteiro's storm petrel, an endemic marine bird of the Azores. Geography Baixo Islet is in fact two basaltic islets, one much larger than the other. The islets are the exposed remains of a Surtseyan cone composed of volcanic tuff rock, heavily eroded by the ocean and seismic activity. The larger main islet is located about southeastof ''Ponta da Restinga'' (''Restinga Point''), which is a small peninsula of Graciosa. It measures or in area, with a highest point of above sea level. Biome The islet and its exposed sea cliffs provide a habitat for ...
