Abstract excerpt

Social animals are faced with a critical decision when sick: to affiliate or withdraw. The behavioural response during an immune challenge varies by individual and species. However, the social and biological factors leading to variation in this decision during an immune challenge are unknown. Here, we explore the affiliative behavioural phenotype, "huddlers" and "non-huddlers," as a social predictor, and...
