Breeding behavior in a flock of Chilean flamingos (Phoenicopterus chilensis) at Dublin zoo

Abstract

The breeding behavior of a flock of Chilean flamingos was observed over a 3-month period during the peak of breeding activity. This species’ habitat is becoming increasingly vulnerable, and concern has been raised over a decline in wild stocks numbers in the past two decades. Breeding programs in zoos have been established, but with limited success because little is known about the precise criteria and conditions required for breeding these animals. This study was undertaken to gain insight into the breeding behavior of captive Chilean flamingos. A catalogue of mating rituals, nest acquisition and defense, and egg incubation behavior was obtained. The results suggest that new additions to the colony may trigger breeding in the subsequent year and that rainfall has little effect on captive reproductive success. Individually identifiable flamingos were followed throughout the breeding season and detailed quantitative data on their nesting, copulation, and social interactions were obtained.
