Betteln junger Mönchssittiche mit abgespreizten Daumenfittichen und Flügelschlagen, Fütterung durch die Altvögel außerhalb des Nestes, besonders heftiges Anbetteln eines fressenden Altvogels.

The film shows the begging of young quaker parrakeets (Myiopsitta monachus), living uncaged in the Institute on the Wilhelminenberg, and subsequent feeding by older birds. Begging is particularly intensive around an adult parrakeet who is eating a fruit. The frequency of the feeding movements is clearly higher than that of the begging movements.
