Kirk's Dik Dik.

                                                             Kirk's Dik Dik                                                                                                                                                          Genetic and behavioural evidence suggests that Kirk's Dik-dik exhibits fidelity in monogamous behaviour. Genetic analysis of off-spring indicate little non-pair parentage. Year-round, Kirk's Dik-diks stay close within pairs, follow each other's activity patterns and spend more than half of their time with their partners, although males give no parental care. The males guard their mates closely during oestrus and over-mark all female scent. This behaviour reduces the likelihood of other males attempting to mate, however, males do attempt to mate with other females on occasion. Genetic monogamy in dik-diks is probably best explained by the behaviour of females: in contrast to many monogamous female birds, female dik-diks do not appear to seek to mate outside the pair-bond.
