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.

Highlights

The problem of biodiversity conservation on the planet is one of the hot spots in science (e.g. [1])
In the middle of the XX century the European roller has disappeared in a number of European countries and in several more – negative trends are observed [3]
The main threats faced by the European roller are: changes in the environment associated with agriculture, the loss of suitable nesting sites, a reduction in the food supply due to an increase in the level of toxicants in the environment, and illegal hunting [5]

Summary

Introduction

The problem of biodiversity conservation on the planet is one of the hot spots in science (e.g. [1]). The conservation of each endangered species often exhibits a mystery and different ways of solving it. The list of such species includes the European roller (Coracias garrulus (Linnaeus, 1758)) [2]. In the middle of the XX century the European roller has disappeared in a number of European countries and in several more – negative trends are observed [3]. In the European part of Russia, there is a reduction in the range and number of the species [4]. The main threats faced by the European roller are: changes in the environment associated with agriculture, the loss of suitable nesting sites, a reduction in the food supply due to an increase in the level of toxicants in the environment, and illegal hunting [5]. The aim of our work was to try to fill this gap
