At minimum, based on odor alone, a giant panda can probably identify the sex, age and individual identity of the scent marker, as well as interpret the marker's mood and reproductive status at the time it left the scent mark. Thus, giant pandas accomplish with scents and sounds what we accomplish with visual and auditory signals. Reproduction Giant panda reproduction is unique among mammals. Mating styles vary considerably among different pairs. Males are sexually active for a longer period in the spring, allowing them to attempt to inseminate more than one female.
Giant pandas exhibit another peculiar evolutionary adaptation known as delayed implantation.
As a result, we do not know precisely the length of the giant panda's actual gestation period. All we can say is that the time from mating to birth ranges from 95 to 160 days. Delayed implantation gives the giant panda more control over when cubs are born because birth dates are not precisely fixed by mating dates. Young may be born in the late summer or in the fall. Overall, however, the general timing of giant panda reproduction is determined by the importance of weaning cubs in the spring, when the newest most protein-filled bamboo shoots are available.
