Leaders are more attractive: birds with bigger yellow breast patches are followed by more group-mates in foraging groups.

Social network theory provides a perfect tool to better understand the population-level consequences of how individuals interact and make their decisions; however, this approach is generally overlooked among evolutionary biologists interested in social relationships. Here, we used social network ana...
