La Portada
La Portada (Spanish: "The Gateway") is a natural arch on the coast of Chile, north of Antofagasta. It is one of fifteen natural monuments included among the protected areas of Chile. There is another similar but smaller structure in the spa town of Pucatrihue, Osorno Province. Description The La Portada Natural Monument covers an area of 31.27 hectares (77.27 acres), and its geomorphological features and remaining fossils stand out in the form of an arch. The arch of La Portada is 43 m (140 ft) high, 23 m (75 ft) wide, and 70 m (230 ft) long. It has a base of black andesite stone, around which are arranged marine sedimentary rocks, a stratum of yellowing sandstone, and layers of the remaining fossils of shells dating back 35 to 2 million years ago. All this was formed during a long process of marine erosion. The arch is surrounded by coastal cliffs that were also formed by marine erosion. They reach a maximum height of 52 m above sea level.

Antofagasta Region
The Antofagasta Region ( es, Región de Antofagasta, ) is one of Chile's sixteen first-order administrative divisions. The second-largest region of Chile in area, it comprises three provinces, Antofagasta, El Loa and Tocopilla. It is bordered to the north by Tarapacá, by Atacama to the south, and to the east by Bolivia and Argentina. The region's capital is the port city of Antofagasta; another one of its important cities is Calama. The region's main economic activity is copper mining in its giant inland porphyry copper systems. Antofagasta's climate is extremely arid, albeit somewhat milder near the coast. Nearly all of the region is devoid of vegetation, except close to the Loa River and at oases such as San Pedro de Atacama. Much of the inland is covered by salt flats, tephra and lava flows, and the coast exhibits prominent cliffs. The region was sparsely populated by indigenous Changos and Atacameños until massive Chilean immigration in conjunction with a saltpete ...

Peruvian Booby
The Peruvian booby (''Sula variegata'') is an endemic bird of the Peruvian current, and an important predator of the marine community to which it belongs. Its distribution is much less widespread than other closely related booby species. It is the most abundant seabird species that inhabits the Peruvian coast and the second most important guano-producing seabird. During the mid-twentieth century, the Peruvian booby population reached 3 million birds. Description The Peruvian booby has brown upperparts, and white underparts, as well as a white head. There is noticeable white mottling on the upper side of the wings. Their wing-coverts are tipped white, creating a scale-like pattern. They have a long, pointed, grey bill. Their feet are webbed and also grey; as opposed to the characteristic colouring of the blue-footed and red-footed boobiesNeotropical Birds Online (T. S. Schulenberg, Editor) (2010).

Landforms Of Antofagasta Region
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are ...

Common Dolphin
The common dolphin (''Delphinus delphis'') is the most abundant cetacean in the world, with a global population of about six million. Despite this fact and its vernacular name, the common dolphin is not thought of as the archetypal dolphin, with that distinction belonging to the bottlenose dolphin due to its popular appearances in aquaria and the media. However, the common dolphin is often depicted in Ancient Greek and Roman art and culture, most notably in a mural painted by the Greek Minoan civilization. It is presently the only member of the genus ''Delphinus''. The common dolphin belongs to the subfamily Delphininae, making this dolphin closely related to the three different species of bottlenose dolphins, humpback dolphins, striped dolphins, spinner dolphins, clymene dolphin, spotted dolphins, fraser's dolphin and the tucuxi and guiana dolphin. The common dolphin was originally categorized into two different species (now thought to be ecotypes), the short-beaked common ...

South American Fur Seal
The South American fur seal (''Arctocephalus australis'') breeds on the coasts of Peru, Chile, the Falkland Islands, Argentina, Uruguay and Brazil. The total population is around 250,000. However, population counts are sparse and outdated. Although Uruguay has long been considered to be the largest population of South American fur seals, recent census data indicates that the largest breeding population of A. a. australis (that breeds in Chile, the Falkland Islands, Argentina, Uruguay) are at the Falkland Islands (estimated pup abundance ~36,000) followed by Uruguay (pup abundance ~31,000). The population of South American fur seals in 1999 was estimated at 390,000, a drop from a 1987 estimate of 500,000 - however a paucity of population data, combined with inconsistent census methods, makes it difficult to interpret global population trends. Description South American fur seals have a dark grey or brown coat of fur. Adult males are much larger than females, with thicker necks an ...

Pelican
Pelicans (genus ''Pelecanus'') are a genus of large water birds that make up the family Pelecanidae. They are characterized by a long beak and a large throat pouch used for catching prey and draining water from the scooped-up contents before swallowing. They have predominantly pale plumage, except for the brown and Peruvian pelicans. The bills, pouches, and bare facial skin of all pelicans become brightly coloured before the breeding season. The eight living pelican species have a patchy global distribution, ranging latitudinally from the tropics to the temperate zone, though they are absent from interior South America and from polar regions and the open ocean. Long thought to be related to frigatebirds, cormorants, tropicbirds, and gannets and boobies, pelicans instead are now known to be most closely related to the shoebill and hamerkop, and are placed in the order Pelecaniformes. Ibises, spoonbills, herons, and bitterns have been classified in the same order. Fo ...

Belcher's Gull
Belcher's gull (''Larus belcheri''), also known as the band-tailed gull, is a bird in the family Laridae found along the Pacific coast of South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the sout .... It formerly included the very similar Olrog's gull as a subspecies, but that bird occurs on the Atlantic coast of South America and is now accepted as ''Larus atlanticus''. Belcher's gull is a medium-sized gull with a blackish mantle, white head and underparts, a black band on the otherwise white tail, and a yellow bill with a red and black tip. Non-breeding adults have a brownish-black head and a white eye-ring. The name of this bird commemorates the British explorer Sir Edward Belcher who performed survey work on the Pacific coast of South America. Description Belcher's gull g ...

Grey Gull
The grey gull, also known as garuma gull (''Leucophaeus modestus'') is a medium-sized gull native to South America. Unusual among gulls, it breeds inland in the extremely dry Atacama Desert in northern Chile, although it is present as a non-breeding bird along much of the Pacific coast of South America. Description The sexes are similar in grey gulls. Adults grow to a length of about and weigh some . The head is white in summer but brownish-grey in winter. The body and wings are grey with the dorsal surface rather darker than the ventral region. The flight feathers are black and the inner primaries and the secondaries have white tips, visible in flight. The tail has a band of black with a white trailing edge. The legs and beak are black and the iris is brown.Josep del Hoyo, Andrew Elliott, Jordi Sargatal (Eds.): ''Handbook of the Birds of the World''. Volume 3: Hoatzin to Auks. Lynx Edicions 1996, , p. 602 The call is similar to that of the laughing gull (''Leucophaeus atricilla ...
