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).
A study demonstrated that monarch butterflies use the sun as a compass to guide their southwesterly autumn migration from Canada to Mexico. Migrating butterflies were captured and held for cycles of 12 hours of light and 12 of dark. One group's light began each day at 7:00 am, while the other group's began 6 hours earlier at 1:00 am.
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.
The organ is a solid, bony structure lined with a film of membranes which air passes through as the songbird calls. While the song boxes of songbirds vary in size and intricacy, this does not necessarily determine the songbird's ability to voice their song. Researchers believe this has more to do with the length of the windpipe. [8]
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.
The northern cardinal is a mid-sized perching songbird with a body length of 21–23 cm (8.3–9.1 in) and a crest on the top of the head. The species expresses sexual dimorphism : Females are a reddish olive color, and have a gray mask around the beak, while males are a vibrant red color, and have a black mask on the face, as well as a larger ...
The common nightingale, rufous nightingale or simply nightingale (Luscinia megarhynchos), is a small passerine bird which is best known for its powerful and beautiful song.It was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae.
