Abstract—The natural quantity of the pied flycatcher in deciduous, mixed, and coniferous forests and reproductive parameters in deciduous and mixed stands of subtaiga forests in the southeast of Western Siberia has been studied comparatively based on materials collected in the period from 1980 to 2017. The natural quantity of the species at the nesting period is greater in mixed and deciduous forests when compared to coniferous forests. Nesting density, clutch size, volume of eggs, success, and productivity of reproduction in nest boxes are higher in deciduous forests. The data on the natural quantity and breeding of pied flycatchers in the study area are compared with the similar indicators in the European part of the range.

INTRODUCTION The pied flycatcher is characterized by a vast nesting range which extends in the longitudinal direction from the coast of the Atlantic Ocean to the Yenisei valley (Glutz and Bauer, 1993; Ryabitsev, 2008). This species is convenient for research due to the fact that it is easy to attract it to controlled areas by hanging artificial nests. In this regard, the pied flycatcher is often used as a model object in population studies. It has been studied well in the European part of the range, and a number of researches are devoted to the biotopic variability of reproductive indices (review: Artemyev, 2008). In the subtaiga forests of Tomsk oblast, breeding of the pied flycatcher in forests with a predominance of deciduous species has been studied (Kuranov, 2018). The data on the reproduction of this species in the forest-steppe zone of Western Siberia are given by Chernyshev (2012). The abundance of pied flycatchers in the nesting period in the subtaiga forests of the Trans-Urals region and Western Siberia is reflected in a number of publications (Ravkin, 1978; Zakharov, 1998; Yudkin, 2002; Toropov and Bochkareva, 2014; Milovidov et al., 2015). However, to date, there are no comparative studies on the characteristics of breeding and natural abundance of pied flycatchers in stands with different species composition in the southeast of Western Siberia. This study, which is based on long-term observations in the Tomsk and Kemerovo oblasts, allowed us to fill this gap to a certain extent. The purpose of this study is to analyze the reproductive indicators and abundance of the pied fly-
catcher in the nesting period under different environmental conditions at the eastern border of distribution, as well as compare them with similar indicators in the European part of the range. MATERIALS AND METHODS The studies were conducted in 1980–201
