text: The social bond hypothesis for food sharing predicts that vampire bats will make cooperative investments of different types (e.g., social grooming, tolerance for feeding at the same source) within the same food-sharing partners over time, alter these cooperative investments slowly depending on how the cooperative returns compare with other individuals (partner choice) and past returns (partner control), and compensate for inabilities to reciprocate food sharing by increasing other services, such as social grooming.
