Madalena Islets
The Madalena Islets ( pt, Ilhéus da Madalena) are two uninhabited islets located in the Faial-Pico Channel about away from Madalena harbor, off the coast of the island of Pico in the Portuguese archipelago of the Azores. The islets are also visible from Horta, Faial, and from the ferries which travel regularly between Horta and Madalena. Locally, the shorter of the two islets is known as ''Ilhéu Deitado'' (''"Lying Down" Islet''), while the taller islet is known as ''Ilhéu em Pé'' (''"Standing Up" Islet''). Geography The Madalena Islets are the exposed remains of a submarine volcano which have been eroded by the sea and seismic activity over the ages. The space between the two islets is the old volcanic crater formed of tuff rock and is approximately deep. The rocks are composed mainly of compacted palagonite tuff. Surrounding waters include sandy clearings and areas of small sea-eroded rocks called ''calhau rolado'' ("rolled pebbles") in Portuguese. ''Ilhéu Deitado'' is ...

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 ...

Brown Algae
Brown algae (singular: alga), comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. They are dominant on rocky shores throughout cooler areas of the world. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, ''Macrocystis'', a kelp of the order Laminariales, may reach in length and forms prominent underwater kelp forests. Kelp forests like these contain a high level of biodiversity. Another example is ''Sargassum'', which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food. Between 1,500 and ...

Common Bottlenose Dolphin
The common bottlenose dolphin or Atlantic bottlenose dolphin (''Tursiops truncatus'') is a wide-ranging marine mammal of the family Delphinidae. The common bottlenose dolphin is a very familiar dolphin due to the wide exposure it gets in captivity in marine parks and dolphinariums, and in movies and television programs.Leatherwood, S., & Reeves, R. (1990). ''The Bottlenose Dolphin''. San Diego: Academic Press, Inc., It is the largest species of the beaked dolphins. It inhabits temperate and tropical oceans throughout the world, and is absent only from polar waters.Klinowska, M. (1991). ''Dolphins, Porpoises and Whales of the World: The IUCN Red Data Book''. Gland, Switzerland, U.K.: IUCN, While formerly known simply as the bottlenose dolphin, this term is now applied to the genus ''Tursiops'' as a whole. As considerable genetic variation has been described within this species, even between neighboring populations, many experts think additional species may be recognized. Taxon ...

Sanderling
The sanderling (''Calidris alba'') is a small wading bird. The name derives from Old English ''sand-yrðling'', "sand-ploughman". The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific, ''alba'', is Latin for "white". It is a circumpolar Arctic breeder, and is a long-distance migrant, wintering south to South America, South Europe, Africa, and Australia. It is highly gregarious in winter, sometimes forming large flocks on coastal mudflats or sandy beaches. It is somewhat unlike other sandpipers in appearance, which has led to the suggestion that it should be placed into a monotypic genus ''Crocethia''. A more recent review (Thomas ''et al.'', 2004) indicates, however, that the sanderling is a fairly typical "stint" or small sandpiper and should be separated from the large knots with its closest relatives in a distinct genus. This bird is similar in size to a dunlin, but stouter, with a ...

Ruddy Turnstone
The ruddy turnstone (''Arenaria interpres'') is a small cosmopolitan wading bird, one of two species of turnstone in the genus ''Arenaria''. It is now classified in the sandpiper family Scolopacidae but was formerly sometimes placed in the plover family Charadriidae. It is a highly migratory bird, breeding in northern parts of Eurasia and North America and flying south to winter on coastlines almost worldwide. It is the only species of turnstone in much of its range and is often known simply as turnstone. Taxonomy The ruddy turnstone was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Tringa interpres''. The species is now placed together with the black turnstone in the genus '' Arenaria'' that was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the ruddy turnstone as the type species. The genus name ''arenaria'' is from Latin ''arenarius'', "inhabiting sand" ...

Roseate Tern
The roseate tern (''Sterna dougallii'') is a species of tern in the family Laridae. The genus name ''Sterna'' is derived from Old English "stearn", "tern", and the specific ''dougallii'' refers to Scottish physician and collector Dr Peter McDougall (1777–1814). "Roseate" refers to the bird's pink breast in breeding plumage. Taxonomy English naturalist George Montagu described the roseate tern in 1813. Genetically, it is most closely related to the white-fronted tern (''S. striata''), with their common ancestor a sister lineage to the black-naped tern (''S. sumatrana''). This species has a number of geographical races, differing mainly in bill colour and minor plumage details. ''S. d. dougallii '' breeds on the Atlantic coasts of Europe and North America, and winters south to the Caribbean and west Africa. Both the European and North American populations have been in long term decline, though active conservation measures have reversed the decline in the last few years at som ...

Grey Heron
The grey heron (''Ardea cinerea'') is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water or stalking its prey through the shallows. Standing up to tall, adults weigh from . They have a white head and neck with a broad black stripe that extends from the eye to the black crest. The body and wings are grey above and the underparts are greyish-white, with some black on the flanks. The long, sharply pointed beak is pinkish-yellow and the legs are brown. The birds breed colonially in spring in "heronries", usually building their nests high in trees. A clutch of usually three to five bluish-gree ...

Eurasian Whimbrel
The Eurasian whimbrel or common whimbrel (''Numenius phaeopus'') is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic Asia and Europe as far south as Scotland. This species and the Hudsonian whimbrel have recently been split, although some taxonomic authorities still consider them to be conspecific. Taxonomy The Eurasian whimbrel was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Scolopax phaeopus''. It is now placed with the curlews in the genus '' Numenius'' that was introduced by the French ornithologist Mathurin Jacques Brisson in 1760. The genus name ''Numenius'' is from Ancient Greek ''noumenios'', a bird mentioned by Hesychius. It is associated with the curlews because it appears to be derived from ''neos'', "new" and ''mene'' "moon", referring to the crescent-shaped bill. The specific epithet ''phaeopus' ...

Cory's Shearwater
Cory's shearwater (''Calonectris borealis'') is a large shearwater in the seabird family Procellariidae. It breeds colonially of rocky islands in the eastern Atlantic. Outside the breeding season it ranges widely in the Atlantic. It was formerly considered to be conspecific with Scopoli's shearwater. Taxonomy Cory's shearwater was formally described in 1881 by the American ornithologist Charles B. Cory from a specimen collected off Chatham Island, Massachusetts. He coined the binomial name ''Puffinus borealis''. Cory's shearwater is now placed in the genus ''Calonectris'' that was introduced in 1915 by the ornithologists Gregory Mathews and Tom Iredale. The genus name combines the Ancient Greek ''kalos'' meaning "good" or "noble" with the genus name ''Nectris'' that was used for shearwaters by the German naturalist Heinrich Kuhl in 1820. The name ''Nectris'' comes from the Ancient Greek ''nēktris'' meaning "swimmer". The specific epithet ''borealis'' is Latin and means "north". ...

Common Tern
The common tern (''Sterna hirundo'') is a seabird in the family Laridae. This bird has a circumpolar distribution, its four subspecies breeding in temperate and subarctic regions of Europe, Asia and North America. It is strongly migratory, wintering in coastal tropical and subtropical regions. Breeding adults have light grey upperparts, white to very light grey underparts, a black cap, orange-red legs, and a narrow pointed bill. Depending on the subspecies, the bill may be mostly red with a black tip or all black. There are several similar species, including the partly sympatric Arctic tern, which can be separated on plumage details, leg and bill colour, or vocalisations. Breeding in a wider range of habitats than any of its relatives, the common tern nests on any flat, poorly vegetated surface close to water, including beaches and islands, and it readily adapts to artificial substrates such as floating rafts. The nest may be a bare scrape in sand or gravel, but it is of ...
