Abstract: During the oestrus season, the brow-antlered deer congregated in larger groups, having a peak in May. The male deer entered the rutting period annually after their antlers hardened,and adult males usually competed combatively with one another for getting access to breeding fcmales.It was not usual for a male to occupy the deer herd solely; there was a linear sequence of hierarchy among them.The oestrus season of C.e.hainanus, based on our observations for 3 ycars(1984-1987), started in January and continued until June with a peak from March to April;the birthing period began in September and ended in the next January with a peak from October to November: The gestation period was approximately seven to seven and a half months. Male shed old antlers and began growing new ones during June to August every ycar;the antlers aged gradually,and from November till the next January the antlers of most male deers became hard-boned.This paper described its sexual behaviors of ten kinds in the reproductive cycle including congregating, fighting, bellowing, wallowing, sniffing, chasing, mounting, copulation, birthing and shedding.
