The social mole-rats of the family Bathyergidae show elaborate organisation that may include division labour between breeders and non-breeders as well across within their groups. However, comparative behavioural data taxa are rare contrasts similarities species poorly understood. Field studies bathyergids usually involve capturing all group members until entire is captured. Because each animal only captured once traps typically placed in close proximity to active foraging areas, order which animals provides an indication activity different individuals spatial burrow system. Here, we compare association capture with breeding status, sex, body mass four subspecies bathyergids, vary size represent three genera Bathyergidae.
