Male hybrids obtained by crossing Bombina bombina with Bombina v. variegata displayed calling behavior when treated with hormones at the age of about 12 months. The mating calls of the hybrids are intermediate with respect to rate, duration, inter-call interval, and fundamental frequency between the calls of the two purebred species.
将东方铃蟾与斑腿铃蟾杂交获得的雄性杂种在约12个月大时用激素处理后表现出鸣叫行为。杂种的交配叫声在速率、持续时间、叫声间隔和基频方面介于两个纯种物种的叫声之间。
