Effects of group size and parentage on patterns of escorting in banded mongooses. (a) Across litters, females were more likely to escort when the litter contained some of their own young, and their probability of escorting decreased with the number of females in the social group (mothers, dark-grey shaded area and solid line; non-mothers, light-grey area and dotted line). (b) Males were less likely to escort when there were more males in the social group, but whether they sired pups did not predict whether they escorted in a given litter. Lines represent model predictions ± s.e. from binomial GLMMs after controlling for random effects of individual, litter and social group.
