The saiga antelope (Saiga tatarica) exhibits a mixed social behavior pattern. They typically form herds during certain periods of the year, such as the breeding season or migration. These herds can range in size from a few individuals to hundreds or even thousands. Within the herd, there is a hierarchical structure, with dominant males competing for breeding rights. However, outside of these specific periods, saiga antelopes may also exhibit more solitary behavior, especially during times of searching for food or during harsh environmental conditions. They are adaptable and can adjust their social behavior based on circumstances and resource availability.
