USA — Pandas are able to identify one another by their calls, according to a study published in the Scientific Reports.<br /><br />Pandas have a more than a dozen distinct vocal sounds they make but when it is time for mating season, there is a distinct sound that both male and female giant pandas use, a husky, rapid vibrato known as a bleat.<br /><br />The bleat helps to alert other pandas if there is a mate available in the area. It also contains information such as the size and identity of the panda.<br /><br />Pandas have a short mating season as the female pandas only ovulate once a year and are able to conceive for only a few days in an year, according to the New York Times.<br /><br />The researchers recorded the bleats of giant pandas and tested how well the sound would travel through dense bamboo thickets.<br /><br />However, the researchers found that the bleat works best if a potential mate is less than 10 meters away.<br /><br />The study could help conservationists trying to encourage pandas to breed as their population continues to dwindle.
