Abstract:From 1991 to 1993, two pairs of Water Rail were kept in differently designed aviaries. In the course of seven breeding cycles their behaviour was observed. After courtship and copulation the male chose the nest site and showed it to the female displaying a typical behaviour. Nest buildig was mainly carried out by the male; in most cases it lasts just one day. Eggs were laid each day, mainly in the early morning. Both partners shared incubation, the mean duration of the incubation interval was significantly longer in the female. Hatching occured asynchronously. The chicks stayed in their nest for approximately five days. Alternatingly both parents fed them and took them under their wings. By about 25 days the chicks were independent. Compared with recordings in literature there were no essential differences with free living pairs.
