社会信息被动物广泛地用来在各种情况下做出决定。关于信息源的状态如何影响社会信息的使用，以及社会信息是否会为移民决策提供信息，人们了解得较少。此外，大多数关于在迁徙背景下使用社会信息的研究都集中在义务迁徙上，但社会信息预计对表现出更灵活迁徙行为的物种尤其重要。在春季迁徙期间，我们在一群圈养的松树(Spinus Pinus)上进行了社会线索的实验测试。西斯金松鼠是游牧候鸟，表现出高度灵活的春季迁徙时期，这与能量储备的增加和圈养中夜间迁徙的躁动有关。从5月份开始，男性和女性受试者被呈现给同性邻居，这些邻居之前要么处于标准光周期(对照邻居)，要么处于更长的夏季光周期(照片先进的邻居，表现出更高级的生殖发育)。我们通过监测夜间迁徙行为、身体状况和生殖发育，评估了这些不同的社会线索在28天内对受试者的影响。与与对照邻居配对的受试者相比，接受拍照的邻居的受试者停止夜间迁徙行为的速度更快。我们还观察到，女性受试者对社交暗示的反应相对较强。受试者的身体状况和生殖发育的变化率在不同的治疗组之间没有差异。这项研究为社会线索如何影响迁徙决策提供了新的见解，并为线索使用的性别差异提供了证据。意义陈述动物在做出决定时经常使用社会信息。不太了解的是，信息源的状况如何影响社会信息的使用，特别是在移徙决策期间。使用一种游牧鸣禽，我们通过实验证明，终止迁徙行为的决定取决于附近同种鸟的状态。这项研究有助于我们理解动物是如何利用社会信息来做出迁徙决策的。
Social information is widely used by animals to inform decisions made in a variety of contexts. Less well understood is how the state of the information source influences social information use and if social information informs migratory decisions. Furthermore, most studies on social information use in the context of migration focus on obligate migrants, yet social information is predicted to be particularly important for species that exhibit more flexible migratory behavior. We experimentally tested for social cue use during the vernal migratory period in a captive population of pine siskins (Spinus pinus). Pine siskins are nomadic migrants that exhibit a highly flexible spring migratory period that is associated with elevated energy reserves and, in captivity, nocturnal migratory restlessness. Beginning in May, male and female subjects were presented same-sex neighbors that were previously maintained on either a standard photoperiod (control neighbors) or a longer, summer photoperiod (photo-advanced neighbors, who exhibited more advanced reproductive development). We assessed the effect of these differing social cues on subjects over 28 days by monitoring nocturnal migratory behavior, body condition, and reproductive development. Subjects presented with photo-advanced neighbors ceased nocturnal migratory behavior more rapidly than subjects paired with control neighbors. We also observed a relatively stronger response to social cues among female subjects. Rates of change in the body condition and reproductive development of subjects did not differ between treatment groups. This study provides novel insight into how social cues can influence migratory decision-making and provides evidence of sex-specific differences in cue use.Significance statementAnimals often use social information when making decisions. Less well understood is how the state of the information source influences social information use, particularly during migratory decision-making. Using a species of nomadic songbird, we experimentally demonstrate that the decision to terminate migratory behavior depends upon the state of nearby conspecifics. This study informs our understanding of how animals use social information to inform migratory decisions.
