Zusammenfassung

Während des Winteraufenthalts auf der Iberischen Halbinsel nimmt beim Kranich der Familienzusammenhalt gegen Frühjahr zu stetig ab. Zunehmende Erfahrung und Geschicklichkeit im Nahrungserwerb macht die Jungvögel allmählich von ihren Eltern unabhängig. In der Regel brechen juv. nach den ad. in Richtung Brutheimat auf.

The increasing feeding efficiency of the yearlings allow them to be progressively more independent of their parents. As a rule, the juveniles depart towards the breeding grounds after the adults.
