Animal migrationAnimal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds, mammals, fish, reptiles, amphibians, insects, and crustaceans. The cause of migration may be local climate, local availability of food, the season of the year or for mating.
Arctic ternThe Arctic tern (Sterna paradisaea) is a tern in the family Laridae. This bird has a circumpolar breeding distribution covering the Arctic and subarctic regions of Europe (as far south as Brittany), Asia, and North America (as far south as Massachusetts). The species is strongly migratory, seeing two summers each year as it migrates along a convoluted route from its northern breeding grounds to the Antarctic coast for the southern summer and back again about six months later.
AlbatrossAlbatrosses, of the biological familyDiomedeidae, are large seabirds related to the procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses). They range widely in the Southern Ocean and the North Pacific. They are absent from the North Atlantic, although fossil remains of short-tailed albatross show they lived there up to the Pleistocene, and occasional vagrants are found.
Altitudinal migrationAltitudinal migration is a short-distance animal migration from lower altitudes to higher altitudes and back. Altitudinal migrants change their elevation with the seasons, making this form of animal migration seasonal. Altitudinal migration can be most commonly observed in species inhabiting temperate or tropical ecosystems. This behavior is commonly seen among avian species but can also be observed within other vertebrates and some invertebrates.
ProcellariiformesOrder of birdsProcellariiformes 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, Procellariiformes are often referred to collectively as the petrels, a term that has been applied to all members of the order, or more commonly all the families except the albatrosses.
ArcticThe Arctic (; from Ancient Greek (árktos)'bear') is the polar region of Earth that surrounds the North Pole, lying north of the Arctic Circle.
AndesMountain range in South AmericaThe Andes ( ), Andes Mountains or Andean Mountain Range (Spanish: Cordillera de los Andes; Quechua: Anti) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 8,900 kilometres (5,500 mi) long and 200 to 700 kilometres (120 to 430 mi) wide (widest between 18°S and 20°Slatitude) and has an average height of about 4,000 metres (13,000 ft).
BirdWarm-blooded animals with wings and feathersBirds are a group of warm-bloodedvertebrateanimals constituting the classAves, 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. They live worldwide and range in size from the 5.5 cm (2.2 in) bee hummingbird to the 2.8 m (9 ft 2 in) common ostrich.
AntarcticThe Antarctic (; US also , commonly ) is the polar region of Earth that surrounds the South Pole, lying within the Antarctic Circle. It is diametrically opposite of the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau, and other island territories located on the Antarctic Plate or south of the Antarctic Convergence.
HimalayasMountain range in AsiaThe Himalayas, or Himalaya, is a mountain range in Asia separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the highest peaks on Earth, including the highest, Mount Everest. More than 100 peaks exceeding elevations of 7,200 metres (23,600 feet) above sea level lie in the Himalayas. The Himalayas span five countries: Nepal, India, China, Bhutan, and Pakistan.
Manx shearwaterThe Manx shearwater (Puffinus puffinus) is a medium-sized shearwater in the seabird family Procellariidae. The scientific name of this species records a name shift: Manx shearwaters were called Manks puffins in the 17th century. Puffin is an Anglo-Norman word (Middle Englishpophyn) for the cured carcasses of nestling shearwaters. The Atlantic puffin acquired the name much later, possibly because of its similar nesting habits.
PredationPredation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. The predator-prey relationship is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually).*As an Amazon Associate I earn from qualifying purchases.
