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.
Karl von Frisch (1953) discovered that honey bee workers can navigate, and indicate the range and direction to food to other workers with a waggle dance.. In 1873, Charles Darwin wrote a letter to Nature magazine, arguing that animals including man have the ability to navigate by dead reckoning, even if a magnetic 'compass' sense and the ability to navigate by the stars is present: [2]
Experiments on European robins, which are migratory, suggest their magnetic sense makes use of the quantum radical pair mechanism. Magnetoreception is a sense which allows an organism to detect the Earth's magnetic field. Animals with this sense include some arthropods, molluscs, and vertebrates (fish, amphibians, reptiles, birds, and mammals).
Magnetoreception is a sense which allows an organism to detect a magnetic field to perceive direction, altitude or location. Experimental data suggests that cryptochromes in the photoreceptor neurons of birds' eyes are involved in magnetic orientation during migration. [55]
Diel vertical migration (DVM), also known as diurnal vertical migration, is a pattern of movement used by some organisms, such as copepods, living in the ocean and in lakes. The adjective "diel" ( IPA : / ˈ d aɪ . ə l / , / ˈ d iː . əl / ) comes from Latin : diēs , lit.
Waterfowl flyways in the United States. The Atlantic Flyway is in violet. The Atlantic Flyway is a major north-south flyway for migratory birds in North America. The route generally starts in Greenland, then follows the Atlantic coast of Canada, then south down the Atlantic Coast of the United States to the tropical areas of South America and the Caribbean.

The song thrush was described by German ornithologist Christian Ludwig Brehm in 1831, and still bears its original scientific name, Turdus philomelos. [3] The generic name, Turdus, is the Latin for thrush, and the specific epithet refers to a character in Greek mythology, Philomela, who had her tongue cut out, but was changed into a singing bird.
