Saiga antelopes typically have their breeding season in the spring, which is generally from April to early June. During this time, male saiga antelopes establish and defend territories, engage in competitive behavior, and mate with females. After mating, females give birth to their calves, usually around May or June. The specific timing of the breeding season can vary depending on environmental conditions, such as temperature and food availability. Please note that my knowledge is based on information available up to September 2021, and I recommend consulting more recent sources for any updates on saiga antelope breeding behavior.
