Knowra Migratory birds Migratory birds Migratory birds travel seasonally between distinct breeding and nonbreeding areas, often returning along regular routes as conditions and resources change.
Bird migration : The recurring seasonal movement of birds between regions, often linked to breeding and food availability. The broader phenomenon includes partial, altitudinal, and other forms beyond journeys between breeding and nonbreeding areas.
East Asian–Australasian Flyway : A major migratory route connecting breeding areas in East Asia with nonbreeding areas in Australasia. Its shorebirds depend on a chain of coastal wetlands across multiple countries.
Ecological connectivity : The movement of organisms, energy, or ecological processes among habitats. Migrants link distant breeding, feeding, and nonbreeding ecosystems.
Arctic tern : A seabird that breeds in the Arctic and migrates to Antarctic waters for the nonbreeding season. Its annual journey is among the longest known animal migrations.
Phenological mismatch : A timing discrepancy between interacting organisms or ecological events that reduces their synchrony. Earlier food peaks may no longer coincide with migrants’ arrival or breeding.
Circannual rhythm : An endogenous biological cycle with a period of about one year. Annual rhythms help time migratory restlessness and seasonal departure.
Atlantic Flyway : A major North American bird migration corridor along the Atlantic coast and inland eastern regions. It concentrates seasonal movements through habitats shared by people and wildlife.
Seed dispersal : The movement of seeds away from their parent plants by animals, wind, water, or other means. Some migrating birds transport seeds between separated habitats.
Bar-tailed godwit : A large shorebird whose populations migrate between Arctic breeding grounds and distant nonbreeding areas. Some populations make exceptionally long nonstop flights across the Pacific.
Migratory connectivity : The degree to which populations at one stage of an annual cycle connect to particular populations at another. Conservation depends on identifying which breeding and nonbreeding populations share routes.
