Abstract
From 1960 to the present day, research on the ecology of the Mute Swan, Cygnus olor, has been carried out in the Volga delta (Krivonosov 1962, 1963, 1972, 1987; Krivenko & Krivonosov 1972; Krivonosov et al. 1976). This research allows us to describe the course and causes of long-term changes in numbers, to determine the main parameters of the local population of the species and to forecast its future.
