Drift migration is the phenomenon in which migrating birds are blown off course by the winds while they are in flight. It is more likely to happen to birds heading south in autumn because the large numbers of inexperienced young birds are less able to compensate than the adults heading north in spring. An example would be an east wind in September blowing Scandinavian migrants such as bluethroats, wrynecks, and the continental race of robin onto the east coast of England and Scotland, leading to temporary concentrations of these species at headlands like Spurn.

dbo:abstract
  • Drift migration is the phenomenon in which migrating birds are blown off course by the winds while they are in flight. It is more likely to happen to birds heading south in autumn because the large numbers of inexperienced young birds are less able to compensate than the adults heading north in spring. Drift is assisted by disorientating conditions such as mist or drizzle, and can result in large numbers of birds arriving together in an area in which they are not normally seen. In the UK this is called a fall, while in the U.S. it is known as a fallout, though in the latter case, it need not involve vagrant birds. An example would be an east wind in September blowing Scandinavian migrants such as bluethroats, wrynecks, and the continental race of robin onto the east coast of England and Scotland, leading to temporary concentrations of these species at headlands like Spurn.

  • Deriva migratoria es un fenómeno de la migración de las aves que ocurre cuando las aves migratorias son sacadas fuera de curso por el viento. Es más probable que ocurra en otoño durante el vuelo hacia los territorios de invernación cuando grandes números de jóvenes inexpertos resultan menos hábiles para compensar la desviación que cuando, ya adultos y experimentados, vuelven a los territorios de cría en la primavera.[cita requerida] La deriva migratoria es propiciada por las condiciones desorentante como la niebla y la llovizna, y pueden resultar en que grandes números de aves lleguen juntas a un área donde normalmente no son vistas. Un ejemplo sería lo que ocurre cuando un viento del este en septiembre sopla en Escandinavia a las migrantes como el ruiseñor pechiazul (Luscinia svecica), el torcecuellos euroasiático (Jynx torquilla), y la raza continental del petirrojo europeo (Erithacus rubecula) hacia la costa este de Inglaterra y Escocia, dando lugar a concentraciones temporales de estas especies en cabos como el de Spurn.
