从三种不同的繁殖种群中获得的斑胸草雀（Taeniopygia guttata castanotis）记录了物种特异性距离呼叫（DCs）：日本育种者使用孟加拉雀作为养父母，日本和美国育种者让自然父母抚养斑胸草雀。对这些叫声进行了五种声学参数的分析，这些参数在野生斑马雀中被证明是两性二态的。雄性斑胸草雀的dc在种群和个体之间是可变的。从孟加拉人饲养的鸟类中记录的雌性dc通常比从斑马雀饲养的鸟类中记录的dc持续时间更长，音调更高，每种种鸟的雄性和雌性在至少一个声学参数上存在差异，但该参数在每种种鸟中都是唯一的。这些结果表明，尽管斑胸草雀的两性二态性在驯化过程中逐渐消失，但至少保留了一种可以区分两性叫声的声学属性。
Species-specific distance calls (DCs) were recorded from Zebra finches (Taeniopygia guttata castanotis) obtained from three different breeding stocks: Japanese breeders that use Bengalese finches as fostering parents, and Japanese and American breeders that let natural parents rear Zebra finches. These calls were analyzed for five acoustic parameters that were shown to be sexually dimorphic in wild Zebra finches. Male Zebra finches had DCs that were variable among breeding stocks and among individuals. Female DCs recorded from Bengalese-fostered birds were generally longer in duration and higher in pitch than those recorded from Zebra-finch-reared birds, males and females in each breeding stock differed in at least one acoustic parameter, but that parameter was unique in each of the breeding stocks. These results suggest that although sexual dimorphism in Zebra finch DCs has gradually disappeared during the process of domestication, at least one acoustic attribute which allows discrimination between the calls of the sexes has been preserved.
