  动物的许多行为表现出雌雄性别差异。扩散是是维持种群延续和新种形成的因素之一,通常也表现出雌雄性别间差异。偏性扩散行为在兽类和鸟类中较常见,而作为唯一具飞翔能力的兽类的蝙蝠的扩散行为的研究则少有报道。棕果蝠(Rousettus leschenaulti)是东南亚较常见的一种果蝠,喜栖息于山洞、废弃房屋、渠道等地,为多雄多雌聚成大群栖息。已有研究发现棕果蝠具有较强的飞翔能力和扩散行为,即使地理距离较远的群体间也少有遗传分化发生。

动物的个体识别在大部分社群行为中具有重要的作用,且物种间识别能力存在很大的差异。先前的研究主要关注信号接收者和它们的识别能力,然而,相对较少的研究关注信号者本身。翼手目动物蝙蝠具有优良的听觉感知系统,且它们主要依靠声学信号来交流。蝙蝠在复杂的行为背景下能够发出丰富多样的社群叫声。
