Like humans, many animals form stable social relationships between specific individuals. These relationships can be extremely beneficial: in humans and other primates individuals with strong relationships tend to be healthier and less anxious.However, there has been little research on other animals and it is not clear how the benefits of social relationships trade off against costs. For instance, spending time with social partners could improve immune function but also increase exposure to infections. Similarly, if you spend most of your time with particular partners you risk missing out on opportunities to learn valuable information from others. To understand these trade-offs and shed light on how and why social relationships evolve, this interdisciplinary project will study jackdaws living in their natural environments where they are subject to competition, predation and disease. Using a combination of state-of the art field experiments, non-invasive stress assays and physiological measures you will examine how variation in the strength of social relationships influences individual stress levels, health and the acquisition of food and knowledge. Jackdaws are members of the large-brained corvid family that form enduring pair bonds embedded within dynamic social networks. Our fieldsites contain thousands of colour-ringed, RFID-tagged jackdaws, providing unique opportunities to quantify the strength of social bonds. Bringing together the supervisory team's expertise in animal cognition and field experiments (Thornton), social relationships and networks (King), behavioural endocrinology (Furtbauer) and disease ecology (Bonneaud) the project will determine how social relationships influence: 1. Stress: You will use non-invasive thermal imaging and hormonal assays to understand whether variability in short-term social interactions (e.g. co-feeding with partners) and long-term sociality measures mediate stress levels. 2. Health: Parasite levels and immune function: Using state-of-the art biomolecular lab techniques you will quantify individual variation in the presence and intensity of various parasitic infections and immunocompetence. 3. Food: using automated feeders that record the identity of all visiting birds, you will test how the presence and identity of social partners alters the probability of displacement and changes food intake. 4. Knowledge: you will seed novel foraging innovations by training individual "demonstrators" to access automated feeders.You will then quantify the cultural transmission of the new behaviour and associated changes in social network structure to determine whether jackdaws can adjust their social associations to learn from knowledgeable individuals. Together, this work will provide important insights into social evolution, cultural transmission and health.

像人类一样，许多动物在特定个体之间形成稳定的社会关系。这些关系可能是极其有益的：在人类和其他灵长类动物中，具有牢固关系的个人往往更健康，焦虑。例如，与社会伴侣共度时光可以改善免疫功能，但也可以增加感染的接触。同样，如果您大部分时间与特定合作伙伴一起度过，您可能会错过从他人那里学习宝贵信息的机会。为了理解这些权衡，并阐明了社会关系的发展以及为什么发展，这个跨学科项目将研究生活在其自然环境中的杰克多，在他们的自然环境中受到竞争，捕食和疾病的影响。结合最先进的现场实验，非侵入性压力分析和生理措施，您将研究社会关系强度的变化如何影响个人压力水平，健康以及食物和知识的获取。杰克多是大脑的Corvid家族的成员，它们形成了嵌入在动态社交网络中的持久债券。我们的田地包含成千上万的颜色圆环，标记为杰克多，提供了独特的机会来量化社会纽带的力量。 Bringing together the supervisory team's expertise in animal cognition and field experiments (Thornton), social relationships and networks (King), behavioural endocrinology (Furtbauer) and disease ecology (Bonneaud) the project will determine how social relationships influence: 1. Stress: You will use non-invasive thermal imaging and hormonal assays to understand whether variability in short-term social interactions (e.g. co-feeding with partners) and long-term社会性措施介导压力水平。 2。健康：寄生虫水平和免疫功能：使用最先进的生物分子实验室技术，您将在各种寄生虫感染和免疫能力的存在和强度下量化个体变化。 3.食物：使用记录所有来访鸟类身份的自动喂食器，您将测试社会伴侣的存在和身份如何改变流离失所的可能性并改变食物摄入量。 4.知识：您将通过培训单个“示威者”来访问自动喂食器来播种新颖的创新。然后，您将量化新行为的文化传播以及社交网络结构中相关的变化，以确定杰克多是否可以调整其社交协会以从知识渊博的人那里学习。这项工作将共同提供对社会进化，文化传播和健康的重要见解。
