群体生活动物中稳定的社会纽带可以提供更多的食物。一个引人注目的例子是，雌性吸血蝙蝠经常将血液回流到与社会联系在一起的亲人和非亲人，而这些亲人和非亲人在夜间捕猎失败。食物共享关系通过偏爱的协会和栖息地内的社交修饰形成。然而，目前尚不清楚这些合作关系是否会延伸到栖息地之外。为了评估吸血蝙蝠的长期合作关系是否在觅食中发挥作用，我们测试了通过接近感应器测量的觅食遭遇是否可以通过野外栖息接近、亲属关系或在圈养21个月期间的共同进食、社会打扮和食物分享的比率来解释。我们评估了6种假设的社会觅食情景的证据，从个人狩猎到集体狩猎。我们发现，紧密结合的雌性吸血蝙蝠分开离开栖息地，但经常在远离栖息地的地方团聚。即使考虑到亲缘关系，重复的觅食遭遇也可以通过栖息地内的联系和圈养中的合作历史来预测。觅食蝙蝠表现出从属和竞争两种互动，每种互动类型都有不同的社交呼唤。我们认为，如果“局部的”栖息地内合作和“全球的”栖息地外竞争增强了频繁的室友之间的健康相互依赖，那么社会觅食可能会对社会进化产生影响。圈养实验和野外接近感应的结合表明，吸血蝙蝠的社会纽带通常由栖息地内的合作互动定义，也延伸到栖息地以外，可能在觅食过程中提供好处。
Stable social bonds in group-living animals can provide greater access to food. A striking example is that female vampire bats often regurgitate blood to socially bonded kin and nonkin that failed in their nightly hunt. Food-sharing relationships form via preferred associations and social grooming within roosts. However, it remains unclear whether these cooperative relationships extend beyond the roost. To evaluate if long-term cooperative relationships in vampire bats play a role in foraging, we tested if foraging encounters measured by proximity sensors could be explained by wild roosting proximity, kinship, or rates of co-feeding, social grooming, and food sharing during 21 months in captivity. We assessed evidence for 6 hypothetical scenarios of social foraging, ranging from individual to collective hunting. We found that closely bonded female vampire bats departed their roost separately, but often reunited far outside the roost. Repeating foraging encounters were predicted by within-roost association and histories of cooperation in captivity, even when accounting for kinship. Foraging bats demonstrated both affiliative and competitive interactions with different social calls linked to each interaction type. We suggest that social foraging could have implications for social evolution if “local” within-roost cooperation and “global” outside-roost competition enhances fitness interdependence between frequent roostmates. A combination of captive experiments and proximity sensing in the wild show that social bonds in vampire bats that are typically defined by cooperative interactions within the roost also extend beyond the roost and may provide benefits during foraging.
