Seabirds
Seabirds (also known as marine birds) are birds that are adaptation, adapted to life within the marine (ocean), 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, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, Reproduction, 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 Bird colony, colonies, which can vary 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 feed on each other. Seabirds can be hig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steamboat
A steamboat is a boat that is marine propulsion, propelled primarily by marine steam engine, steam power, typically driving propellers or Paddle steamer, paddlewheels. Steamboats sometimes use the ship prefix, prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. The term ''steamboat'' is used to refer to smaller, insular, steam-powered boats working on lakes and rivers, particularly riverboats. As using steam became more reliable, steam power became applied to larger, ocean-going vessels. Background Limitations of the Newcomen steam engine Early steamboat designs used Newcomen atmospheric engine, Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The Newcomen engine also produced a reciprocating or rocking motion because it was designed for pumping. The piston stroke was caused by a water jet i ...

Ship
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and ...

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poikilocarbo Gaimardi
The red-legged cormorant (''Poikilocarbo gaimardi''), also known as the red-legged shag, red-footed cormorant, red-footed shag, Gaimard's cormorant and grey cormorant,Nelson, J. B. 2005. Cormorants and shags. Pages 512–14. In C. M. Perrins, W. J. Bock and J. Kikkawa, eds. Pelicans, Cormorants, and their Relatives. Oxford University Press, New York. is a species of cormorant resident to the coastline of South America. It is the only member of the genus ''Poikilocarbo.'' It is non-colonial unlike most seabirds. The red-legged cormorant has not been observed wing-spreading, which is unusual among cormorant species.Johnsgard, P. A. 1993. Cormorants and shags (Phalacrocoracidae). Pages 311–314 In A. Matthew, ed. Cormorants, Darters and Pelicans of the World. Smithsonian Institution Press, Washington.

Neotropic Cormorant
The neotropic cormorant or olivaceous cormorant (''Nannopterum brasilianum'') is a medium-sized cormorant found throughout the American tropics and subtropics, from the middle Rio Grande and the Gulf and Californian coasts of the United States south through Mexico and Central America to southern South America, where it is called by the indigenous name of ''biguá''. It also breeds on the Bahamas, Cuba and Trinidad. It can be found both at coasts (including some mangrove areas) and on inland waters. There are at least two subspecies: ''N. b. mexicanum'' from Nicaragua northwards and ''N. b. brasilianum'' further south. In Peru the neotropic cormorant is used by the Uru people for fishing. Taxonomy The neotropic cormorant was documented in 1658 by the Dutch naturalist Willem Piso after travels in Brazil. This formed the basis for the formal description and naming of the species by Johann Friedrich Gmelin in 1789. He placed it with the petrels in the genus ''Procellaria'' and coined ...

Pelecanus Thagus
The Peruvian pelican (''Pelecanus thagus'') is a member of the pelican family. It lives on the west coast of South America, breeding in loose colonies from about 33.5° in central Chile to Piura in northern Peru, and occurring as a visitor in southern Chile and Ecuador.Handbook of the Birds of the World AlivePeruvian pelican.Retrieved 21 May 2017. Description These birds are dark in colour with a white stripe from the top of the bill up to the crown and down the sides of the neck. They have long tufted feathers on the top of their heads. It was previously considered a subspecies of the brown pelican (''Pelecanus occidentalis''). The Peruvian pelican is considerably larger, ranging from about in weight, in length and with a wingspan of about . Compared to the brown pelican, it also has proportionally longer crest feathers, as well as differences in the colours of the gular pouch, beak, scapulars and greater wing coverts.

Sula Variegata
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).

Larosterna Inca
The Inca tern (''Larosterna inca'') is a tern in the family Laridae. It is the only member of the genus ''Larosterna''. This uniquely plumaged bird breeds on the coasts of Peru and Chile, and is restricted to the Humboldt Current. In 2021 a single Inca Tern successfully made the south shores of Oahu and Hawaii (Big) Island, its home. It is an erratic, rare visitor to the southwest coast of Ecuador. It can be identified by its dark grey body, white moustache on both sides of its head, and red-orange beak and feet. Description The Inca tern is a large tern, approximately long. Sexes are similar; the adult is mostly slate-grey with white restricted to the facial plumes and the trailing edges of the wings. The large bill and legs are dark red. Immature birds are purple-brown, and gradually develop the facial plumes. Behaviour Breeding The Inca tern breeds on rocky cliffs. It nests in a hollow or burrow or sometimes the old nest of a Humboldt penguin, and lays one or two eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalacrocorax Bougainvillii
The Guanay cormorant or Guanay shag (''Leucocarbo bougainvilliorum'') is a member of the cormorant family found on the Pacific coast of Peru and northern Chile. (The Argentinian population on the Patagonian Atlantic coast appears to be extirpated.) After breeding it spreads south to southern parts of Chile and north to Ecuador, and has also been recorded as far north as Panama and Colombia – probably a result of mass dispersal due to food shortage in El Niño years. Its major habitats include shallow seawater and rocky shores. The Guanay cormorant is similar in coloration to the rock shag, ''Leucocarbo magellanicus'', but larger, measuring 78 cm from the tip of the bill to the end of the tail. Its bill is grayish with some red at the base. The face is red with a green eye-ring. It has roseate feet. The head, neck and back are black as are the outer parts of the thighs. The throat patch, breast and belly are white. In breeding plumage it has a few white feathers on the side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
