Panda romance

If you're a giant panda, this sound means romance. "I wouldn't call it a romantic serenade" Megan Owen, a conservation biologist at the San Diego Zoo’s Institute for Conservation Research. "There's nothing soft or demure about it." And yet: that sound, called a bleat, "that's B-L-E-A-T, just like a goat" signals that a panda couple has hit it off, and copulation is nigh.

Owen and her colleagues analyzed more than 2,500 panda sounds recorded during breeding introductions, and analyzed the audio’s acoustic qualities. Their study, in the journal Royal Society Open Science, is a sort of how-to guide for panda breeders, cataloguing the various vocal characteristics of a blind date: an uninterested roar or bark; a more ambiguous chirp; or an amorous bleat.

Decoding the sounds could be important not just for boosting panda numbers, Owen says, but for avoiding very bad dates. "These are bears and they have sharp teeth and claws and they can do a lot of damage to one another if they don't want to be around each other."

And these fine-tuned communication skills also make the case that the social lives of pandas are anything but black and white.

如果你是一只大熊猫,这种声音意味着浪漫。圣地亚哥动物园保护研究所的生物保护学家梅根欧文说,我觉得这叫声并不浪漫,因为听起来毫无温柔矜持可言。然而这种山羊一样的咩咩叫,意味着一对熊猫很合得来,交配近在眼前了。

欧文和同事分析了两千五百多只熊猫在繁殖过程中的录音,并分析了这些录音的声学特性。他们的研究发表在皇家学会开放科学杂志上,这种声音分析方法为熊猫饲养员提供了指导,他们对相亲时的各种声学含义进行分类:吼声或吠声表示不感兴趣,唧唧声表示态度暧昧,咩咩叫表示含情脉脉。

欧文说,破译这些声音不仅有利于促进熊猫数量增长,还可以避免约会失败。熊猫是熊类,它们爪牙锋利,如果不想呆在一起,会彼此造成巨大伤害。

而这些微妙的沟通技巧也证明:熊猫虽然黑白分明,但它们的社交生活并非黑白分明。
