动物群体中人格特征的发现可能有助于解释育种策略中的个体差异。在白色领黑鸟Turdus albocinctus，女性，而不是男性，表现出不同的巢防御行为，可以用来将它们分为大胆和害羞的个性。大胆的雌性比害羞的雌性有更高的巢成功率，更低的繁殖力和更高的父母投资，大胆的雌性的社会伴侣比害羞的雌性有更低的父母投资。我们的研究结果表明，鸟类的繁殖策略可能与它们的人格特征密切相关。
The discovery of personality traits in animal populations may help to explain individual variation in breeding strategies. In the White‐collared BlackbirdTurdus albocinctus, females, but not males, exhibited different nest defence behaviours that can be used to classify them into bold and shy personalities. Bold females had higher nest success, lower fecundity and higher parental investment than shy females, and the social mates of bold females had lower parental investment than that of shy females. Our findings suggest that the reproductive strategy of birds may be closely related to their personality traits.
