Flußseeschwalben mit Jungen und Ei am Nest. Brutablösung, Aufrafftriebäußerungen der Altvögel nach der Ablösung (Schleudern und Verlegen), Betteln der Jungvögel, Fortbewegung und Verlegen von trockenen Stengeln durch die zwei Tage alten Jungen. : Behaviour of a pair of terns while incubating and taking their young under their wings. Apart from the ceremony of changing shifts (with instinctive rousing activities and egg rolling movements), the performance of the parents in taking the young under their wings is demonstrated. Of particular interest from a behaviour science point of view are the rousing efforts of a two days old bird still in the nest.
