Term	Definition
Breeding dispersal	Animals emigrate from a social group where they have bred [1].
Dispersal	Animals emigrate from one social group and immigrate into another [1]. The term “biased” is used to describe the relative frequencies of male and female dispersal. For instance, male-biased dispersal means that more males than females disperse, but it does not indicate the degree of sex bias.
Bonded groups	Indicates strong social relationships within groups, either between males (male bonded), between males and females (male-female bonded), or between females (female bonded) [19].
Immigrant	An animal that resides in a different social group than where it was born.
Kin-based groups	Groups consist of related animals of the same sex. Female kin-based groups consist of mostly female kin and male non-kin. Male kin-based groups consist of mostly male kin and female non-kin [48].
Natal	An animal that resides in the social group where it was born.
Natal dispersal	Animals emigrate from the social group where they were born before they start to breed [1].
Parallel dispersal	Animals transfer between groups together, or they disperse singly to groups that already contain kin or other familiar animals (i.e. animals with whom they co-resided with at some point) [49].
Philopatry	Animals remain in the group where they were born [1]. Female-biased philopatry means that more females than males remain in their natal groups.
