The avifauna of Western Siberia taiga zone wetlands (Tomsk oblast)

Abstract

Wetland landscapes are widely spread in the Western Siberia taiga zone. Wetlands serve climatic and hydrological global functions, as well as many others. They also form the habitats for many species of animals. Dynamic development of Western Siberia wetlands and human influence on them demand the investigation of the wetlands’ bird population. This study aims to determine the wetland avifauna species diversity and to evaluate bird abundance and current state of rare species listed in Red Data Book. The study was carried out in the southern and middle taiga zones and in subtaiga. The study is based on the surveys that authors made in 2007–2013 in Tomsk oblast and also on the data gathered by the scientists in the Western Siberia forest zone. Counts were made according to Y.S. Ravkin’s methods. Counts of bird density are based on mean discovery distance on the routes. A total of 600 km walking and 150 water counting routes (by boats) were covered. It was found that 225 bird species inhabit Western Siberia wetland landscapes (196 – Tomsk oblast). Near 80% of birds inhabiting wetlands nest here.
