Like many birds, seabirds often migrate after the breeding season. Of these, the trip taken by the Arctic tern is the farthest of any bird, crossing the equator in order to spend the Austral summer in Antarctica. Other species also undertake trans-equatorial trips, both from the north to the south, and from south to north.
Migration is the regular seasonal movement, often north and south, undertaken by many species of birds. Migration is marked by its annual seasonality and movement between breeding and non-breeding areas. [16] Nonmigratory bird movements include those made in response to environmental changes including in food availability, habitat, or weather.
You can help build this list by migrating species from the List of Pelecaniformes by population to align it with the article Pelecaniformes.. Suliformes include the following families: Sulidae (gannets and boobies), Fregatidae (frigatebirds), Phalacrocoracidae (cormorants), Anhingidae (darters), and the Plotopteridae (flightless seabirds of the North Pacific that went extinct in the Miocene).
A 2006 study found individual tagged sooty shearwaters from New Zealand migrating 64,000 km (40,000 mi) a year, [2] which gave them the then longest known animal migration ever recorded electronically (though subsequently greatly exceeded by a tagged arctic tern migrating 96,000 km (60,000 mi) [3]).

Seawatching is commonly performed during bird migration seasons, and particularly when weather conditions are suitable. Successful seawatching is very dependent on the weather. [ 2 ] When the weather is fine, birds often stay out to sea, and pelagic trips are then a more effective way to observe them; if onshore winds combine with rain , birds ...
The migration also appears to be quite complex, containing many stopovers and foraging zones throughout the Atlantic Ocean. [28] Ornithologist Chris Mead estimated that a bird ringed in 1957 when aged about 5 years and still breeding on Bardsey Island off Wales in April 2002 had flown over 8 million km (5 million mi) in total during its 50-year ...
Adult near Burrow on Bruny Island. The photograph was taken at night. Fledgling, Austins Ferry, Tasmania, Australia. The short-tailed shearwater or slender-billed shearwater (Ardenna tenuirostris; formerly Puffinus tenuirostris), also called yolla or moonbird, and commonly known as the muttonbird in Australia, is the most abundant seabird species in Australian waters, and is one of the few ...
