Abstract: Same bat family... Kinship is an important factor in the maintenance of cooperative behaviours but strategies that increase kinship within social groups might be expected to have a downside in the shape of excessive inbreeding. Female greater horseshoe bats, however, have adopted two novel breeding behaviours that raise kinship in a colony without increasing inbreeding. Most females revisit and breed with specific individual males across the years; and mother and daughters regularly breed with the same male, yet nearly always avoid their blood relatives.
