Abstract
In the article, the authors shared the results of their research on the fertility of the offspring of magpies, which are one of the most common species of synanthropic birds in the northern regions of Kazakhstan, including in Pavlodar and its environs. The authors attempt to reveal the main reasons for changes in the reproduction rate and population dynamics of magpies. It is concluded that the number and activity of enemies that destroy eggs and chicks in magpies can vary in different periods of the year. The purpose of their research was to analyze changes in the reproduction rate and the dynamics of the number of magpies for 2018-2019. The researchers note that the parental behavior of magpies in different birds is significantly different, often even polar opposites, and the work of the observer with the magpies ‘ nests can serve as a model of the situation when the offspring is threatened by potential danger.
