摘要

火烈鸟(Phoenicopteriformes)是专性的群体物种,它们在大的群体中筑巢,一夫一妻制的一对在同步的群体求爱后抚养一只小鸡。在这种相对简单的行为描述中,明显偏离了这些社会和生殖规范。同性配对,多鸟关系和多对交配在文献中都有记载。火烈鸟表现出高度的性选择特征,如羽毛颜色、类胡萝卜素的积累和展示动作的多样性,这些都是择偶决定的基础。身体状况最好、颜色最亮的鸟在繁殖方面更成功。因此,有记录的雄性伴侣对雌鸟的配偶保护,是对配偶关系投资最大化的相关反应。有限的信息,描述的行动,由雄性火烈鸟的强迫交配和雌鸟的反应是可用的文献。这篇论文描述了一只年长的雄性大火烈鸟试图与一只年轻的雌性鸟交配的事件。这种行为可能是圈养环境的人工产物,与野生种群的规模相比,配偶选择有限,或者它可能在野生环境中经常出现,因此值得更多的审查和实证研究。

Observation of an Attempted Forced Copulation within a Captive Flock of Greater Flamingos (Phoenicopterus roseus)
Flamingos (Phoenicopteriformes) are obligate colonial species that nest in large colonies, with monogamous pairs rearing a single chick following a synchronised group courtship display. Within this relatively simplistic behavioural description, deviations from these social and reproductive norms are apparent. Same sex pairings, multi-bird relationships and extra pair copulations are documented in the literature. Flamingos display highly sexually selected characteristics of plumage colour, carotenoid accumulation and diversity of display movements that underpin mate choice decisions. The brightest birds in best body condition are more successful at breeding. Therefore, documented mate guarding of female birds by male partners, is a relevant response to maximise investment in a pair bond. Limited information that describes the action of forced copulation by the male flamingo and the response of the female bird is available in the literature. This paper describes an occurrence of an attempted forced copulation by an older male Greater Flamingo to a younger female bird. Such behaviour may be an artefact of the captive environment, and limited mate choice when compared to the sizes of wild flocks, or it could be regularly apparent in the wild and therefore worthy of more scrutiny and empirical study.
