ABSTRACT
The parental behavior of beluga whales observed in a summer reproductive gathering (near Solovetsky Island, Onega Bay, White Sea) is described, including the parturition process. A tight association between the female and its newborn infant has been traced by the case study of a stillborn calf. Individual behavioral patterns of a mother and calves observable only in natural habitats are detailed.

Elements of behavior under natural conditions, their duration, and frequency are described in three age groups of belugas calves: newborn, one-month-old, and two-month-old. The quantitative and qualitative indices of the recognized behavioral elements allowed us to evaluate the mother-infant contacts and to analyze their dynamics during calf growth. The most common calf positions relative to the mother during this period were "at the cow's tail" and "at the cow's side." The importance of behavioral responses of calf for the development of social behavior in adult animals is emphasized.
