ориентация залетных птиц, измеренная с помощью радиотелеметии
Вот неплохое подтверждение тому, что редкие залетные птицы появляются далеко в стороне от своих обычных путей миграции благодаря нарушениям в системе ориентации. Впрочем, такие нарушения части особей в популяции могут оказаться адаптивны на большом отрезке времени.

Abstract
Migratory birds are frequently found far outside their normal range but the phenomenon is poorly understood. We used radio telemetry to track individual migratory flights of several species of songbirds on the Faroe Islands, far west of their normal migration route. Birds with expected easterly and south-easterly migration direction departed westwards out over the Atlantic Ocean, indicating that these birds are actively flying in the "wrong" direction and that their occurrence is not caused by wind drift. This is in contrast to the apparently normal south-westerly to easterly departure directions in birds expected to migrate south or southwest.
