Estimation of demographics of self-sustaining groups of pied flycatcher <i>Ficedula hypoleuca</i> (Passeriformes: Muscipapidae) taking into account the long-term dynamics of the population breeding in the Tomsk oblast (Western Siberia)

We present the main demographic parameters of the Western Siberian pied flycatcher population, nesting in natural habitats, at different stages of population dynamics. The average values, range, boundaries, and direction of changes in the survival of sexually mature individuals, fecundity, and the encounter probability at different ages were analyzed. Using matrix models of population structure and population dynamics, an estimate of the true survival rate of fledglings is given. The range of values of demographic parameters that characterize viable groups of the studied bird species is indicated.
