Subject Area
Nest mit adulten und jungen Flußseeschwalben. Bettelnde, zwei Tage alte Jungvögel, Anbieten der Beute durch die Altvögel, Annehmen und Verweigern der Nahrung, Fehlhandlungen bei der Fütterung. Bei älteren, flüggen und fast flugfähigen Jungen aggressives Bedrängen der Altvögel während der Fütterung. Sexuelle Triebhandlungen mit Jungvögeln.
Feeding of young terns. Different stages (2 days old until fledged young) were chosen in order to demonstrate differences in the behaviour of parents and young birds. Of special interest are instinctive sexual actions (attempts at copulation with a 10-day old bird) that were induced by begging of the young.
