在自然条件下的行为，其持续时间和频率的元素被描述在三个年龄组的白鲸小牛：新生儿，一个月大，两个月大。定量和定性指标的公认的行为元素，使我们能够评估母婴接触，并分析其动态在小牛的生长。在此期间，小牛相对于母亲最常见的位置是“在牛的尾巴上”和“在牛的旁边”。强调了犊牛行为反应对成年动物社会行为发育的重要性。
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.
