Short summary
Coalitions are a specific case of cooperative competition and have been explained by various factors like partner availability, distribution of fighting ability, or cost of coordination. We investigated if age is an important factor influencing coalition formation and, specifically, if males switch from a solo strategy to a cooperative one after reaching post-prime age. We found that older males formed more coalitions than younger ones, stressing the importance of age in cooperative competition.
