It is a 1995 book by Steve N. G. Howell and Sophie Webb, published by Oxford University Press. A 60-page introduction outlines the geographical area covered, explains the areas geography and bird distribution within it, and discusses climate and habitat, and bird migration.
Bird migration is controlled primarily by day length, signalled by hormonal changes in the bird's body. [20] On migration, birds navigate using multiple senses. Many birds use a sun compass, requiring them to compensate for the sun's changing position with time of day. [21] Navigation involves the ability to detect magnetic fields.
Zugunruhe is borrowed from German; it is a German compound word consisting of Zug, "move, migration," and unruhe (anxiety, restlessness). The word was first published in 1707, when it was used to describe the "inborn migratory urge" in captive migrants.
Ronald Lockley (1903–2000), among many studies of birds in over fifty books, pioneered the science of bird migration. He made a twelve-year study of shearwaters such as the Manx shearwater, living on the remote island of Skokholm. [7]
An analysis of bird strike data from three airports local to New York City and New Jersey from 2013 to 2018 indicates that 90% of reported bird strikes involved a migratory species, and 50% of strikes occurred during peak annual migration months in the spring and fall. [20]
Further comments upon the manner birds migrate - namely the causes, which start on migration - and upon the way they orient themselves during migration, resulted in the hypothesis of the "inner time" and "inner space", which, along with their known senses, allow the migratory birds to perfect the migratory act in time and space.
Animal 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. [5] It is found in all major animal groups, including birds, [6] mammals, [7] fish, [8] [9] reptiles, [10] amphibians, insects, [11] and crustaceans.
