I bet you have been wondering what Zugunruhe means. It is a research term (German Zug meaning move or migration and Unruhe meaning anxiety or restlessness). It describes the, apparently, innate behavior that birds exhibit just prior to and during migration. Caged birds, for instance, which would be getting ready to migrate if they were not locked up, are often seen to become agitated and sometimes to orient themselves in the direction in which they (believe) they would be migrating. The parenthetical because experiments which proved the existence of the phenomenon purposely disoriented the birds being studied.
