Reproductive behavior of the european roller (Coracias garrulus Linnaeus, 1758)

Abstract

In the European part of Russia, there is a decrease in the area and number of the European Roller. We performed a preliminary study of the role of behavioral ecology in the survival of the species. The material was collected in the Stavropol krai in 2004, 2006-2019. Females and males were distinguished by color intensity (females' plumage is paler) and behavior. Birds exhibit complex biocommunication with features of a foraging economy, distribution of parental roles, and high coordination of partner actions. Additional research is needed to elucidate the behavior of birds whose partners died in the flyover or wintering areas.
