Grouping pattern of Japanese Wild boar (Sus scrofa leucomystax)

Abstract

Seven types of social group were recognized for adult Japanese wild boars (≥2 years old). However, males were always solitary and females most frequently formed basic family groups (1 female with her youngs). Since a basic family group contains only one adult (mother) it is concluded that both male and female Japanese wild boars were basically solitary. Continuous observations on social groups revealed that group formations in adults changed throughout the year in relation to the timing of farrowing.
