Ablenkungsmanöver bei der Eiablage des Häherkuckucks(Clamator glandarius)

Abstract

A pair of the Great Spotted Cuckoo exhibited reproductive behaviour during the years 1968–72. Until 1971 the female laid the eggs in nests of Magpies or Blackbirds which were placed in the aviary. Birds which could serve as hosts at these times were not in the aviary. The female Cuckoo visited the nests before laying an egg quite often and stayed at or in the nests for longer periods.
