The distinctive and divergent courtship phenotypes of the birds-of-paradise make them an important group for gaining insights into the evolution of sexually selected phenotypic evolution. The genus includes five long-tailed species that inhabit New Guinea's montane forests. The visual and acoustic components of courtship among species are very poorly known. In this study, we use audiovisual data from a natural history collection of animal behavior to fill gaps in knowledge about the visual and acoustic components of courtship. We report seven distinct male behaviors and two female specific behaviors along with distinct vocalizations and wing-produced sonations for all five species. These results provide the most complete assessment of courtship in the genus to date and provide a valuable baseline for future research, including comparative and evolutionary studies among these and other bird-of-paradise species.
极乐鸟独特且多样的求偶表型使它们成为深入了解性选择表型进化的重要群体。该属包括五个栖息于新几内亚山地森林的长尾物种。对于该属物种求偶行为中的视觉和听觉成分，我们知之甚少。在本研究中，我们利用动物行为自然历史馆藏中的视听数据，来填补关于该属求偶行为的视觉和听觉成分方面的知识空白。我们报告了所有五个物种的七种不同雄性行为和两种雌性特定行为，以及独特的叫声和翅膀发出的声音。这些结果提供了迄今为止对该属求偶行为最全面的评估，并为未来的研究，包括这些物种与其他极乐鸟物种之间的比较和进化研究，提供了有价值的基线。
