The daily and seasonal vocalization of the red fox was traced. Year-round studies were carried out using digital voice recorders. Fox barking was recorded in the frequency range from 700 to 3600 Hz. The cackling of the fox was recorded in the frequency range from 500 to 2500 Hz. Fox calls were recorded in all seasons of the year, but the most pronounced peaks of prolonged activity in the year were recorded in spring and autumn. The vocal activity of the red fox was noted for the entire period of the study from 17:51 to 01:38. During this period, the total duration of calls in the red fox varied from 34 sec to 27 min per day, 4 min on average. 86% of all call registrations in the region occurred before midnight, the rest (14%) after midnight. Vocalization began after sunset for an average of 2 h 49 min.

The article considers the co-vocalisation of Eagle Owl and other species of owls. The studies were carried out using digital voice recorders in the habitats of the eagle owl. The natural and climatic conditions of the area in which co-vocalisation was noted were analyzed. Rare cases of co-vocalisation of Eagle Owl and its prey, primarily the Ural Owl and the Longeared Owl, have been identified. Co-vocalisation was revealed only in winter and spring. This is due to the breeding season of birds. The presented study reflects the environmental sustainability of a particular area.

В статье отражена история зарождения социоестественной исто-рии и деятельность ее основателя – Эдуарда Сальмановича Кульпина – по утверждению и развитию этого перспективного научного направления. В свете коренного изменения места и роли человека в природе и обществе предлагается обоснование идеи формирования адекватной мировоззренческой парадигмы. В этом контексте очерчивается проблематика социоестественной истории как одного из актуальных направлений исследований сообщества ученых, составляющих творческий актив и читательское сообщество журнала «История и современность». The article describes the history of formation socionatural history and the contribu-tion of its founder Eduard Salmanovich Kulpin to the development of this promising scientific direction and proving its validity. In terms of radical changes of the place and role of a human in nature and society a justification for the establishment of adequate worldview paradigm is provided. In this context, the author outlines the problems of socionatural history as one of the important directions of research of scientific community which makes up the creative assets and audience of the journal “Istoria i sovremennost”.
