For example, a mother may respond to this vocalization by repositioning the cub. Additionally, their vision is not acute, and they rarely come into direct contact with each other. Thus, giant pandas rely little on visual signals for communication. Body postures in conjunction with vocalizations are used during direct confrontations between pandas. Reproduction Giant panda females generally only come into estrus once a year, during the spring.
Female behavior changes noticeably during estrus.
Initially, scent marking increases greatly. As the estrous period progresses, the female will bleat and urinate more frequently. Some females also play and splash in water, roll, and walk backwards. In the wild, males are drawn to females by their scent marking. Males congregate around the estrous female and compete for access to her.
