摘要雀形目鸟类的雄性在其配偶的生育期唱歌最活跃，部分是作为一种父权保护策略，部分是为了最大限度地提高自己的额外配对交配成功率。这项调查认为，无论是作为一个父亲的后卫战略，在雪纺，柳莺。这项研究是在1993年和1994年期间在英格兰东南部（Wytham Woods，牛津）进行的。歌曲率计算为5分钟的时间内，鸟花唱歌的比例，在黎明或中午采样。雄性灰雀在雌性灰雀的生育期并没有唱得更多，这与父权守卫假说相矛盾。在繁殖期，当雌性出现时，鸣唱率下降，这表明雄性唱歌是为了与配偶联系。有人建议，在肥沃的时期之后，歌曲被用来向邻国宣布一个已建立的领土。这也可能使男性重新迅速交配后巢捕食或以下女性遗弃或捕食，同时尽量减少昂贵的领土斗争。
Abstract It has been suggested that males of passerine bird species sing most actively during the fertile period of their mates partly as a paternity guard strategy and partly to maximize their own extra-pair copulation success. This investigation considers whether song is used as a paternity guard strategy in the chiffchaff,Phylloscopus collybita. The study was carried out in south-eastern England (Wytham Woods, Oxford) during 1993 and 1994. Song rate was calculated as the proportion of a 5-min period a bird spent singing, sampled either at dawn or at noon. Male chiffchaffs did not sing more during the fertile period of their females contradicting the paternity guard hypothesis. During the fertile period, song rate decreased when the female was present, suggesting that males sing to contact their mates. It is suggested that after the fertile period song is used to proclaim an established territory to the neighbours. This might also allow the male to re-mate quickly following nest predation or following female desertion or predation, while minimizing expensive territorial fights.
