繁殖栖息地的选择强烈影响繁殖和个体的适应性。在鸟类中，利用同种的社会线索来选择栖息地是很普遍的，但不同类型的同种社会线索如何影响繁殖栖息地的选择仍然不太清楚。黄莺（Setophaga petechia）是一种有两种歌唱类别与配对状态相关联的物种，我们通过回放实验来评估黄莺在选择繁殖栖息地时是否使用不同的类别。我们假设黄莺在选择栖息地时使用的是第二类鸣叫模式（主要由雄性配对鸣叫），而不是第一类鸣叫模式，因为配对成功的雄性鸣叫模式表明栖息地质量更高。我们在伊利诺斯州的一些地点播放黄莺的第一类鸣叫模式、第二类鸣叫模式和无声控制。黄莺在二类鸣声处理的地点数量较多。我们的研究结果表明，黄莺在选择繁殖栖息地时使用社会线索而不是其他类型的社会线索来通知成功的配对。
Breeding habitat selection strongly affects reproduction and individual fitness. Among birds, using social cues from conspecifics to select habitat is widespread, but how different types of conspecific social cues influence breeding habitat selection remains less understood. We conducted a playback experiment evaluating if the yellow warbler ( Setophaga petechia ), a species with two song categories linked to pairing status, uses categories differently when selecting breeding habitat. We hypothesized that yellow warblers use second-category singing mode, which is mostly sung by paired males, over first-category singing mode for habitat selection, as successfully paired males should indicate higher-quality habitat. We broadcast yellow warbler first-category singing mode, second-category singing mode, and silent controls at sites in Illinois. Yellow warblers were more abundant at sites treated with second-category singing mode compared other sites. Our results demonstrate that yellow warblers use social cues informing successful pairing over other types of social cues to select breeding habitat.
