[2] During this 'flight', they emit trumpet-like "zik-zik" calls to raise an alarm or to harass predators and publicize the presence of a mated pair.

[2] They are dainty creatures with a pointed, mobile snout, large eyes and ears, prominent preorbital glands, pipestem legs, hare-like hind limbs that are significantly larger than their forelimbs, and a vestigial tail.

[2] Their coats, depending upon their habitat,[5] range from grey to gray-brown with tan flanks, limbs, and an erectile head crest and whitish eye rings, ear lining, underparts, and rump.

[4] Kirk's dik-diks are sexually dimorphic; females are larger and lack horns, while males sport a more developed muzzle, have a longer crest, and tend to be lighter in color.

[2] Water- and energy-conserving methods, such as fluctuating body temperatures, lowered metabolic rates, concentrated urine, and dry feces, all contribute to the ability of the dik-dik to survive harsh arid climates.

[4] Behaviorally, dik-diks are highly nocturnal, and during the daytime seek shade to rest throughout the hottest parts of the day to help avoid the loss of valuable fluids.

[5] Typical habitats of Kirk's dik-dik consist of thicket mosaics characterized by well-developed shrub layers and scant short grass cover.

[4] (Kingdon 1982) According to MacDonald (1985), territorial conflicts over quality habitat are not frequent, however, when do they occur, males charge one another, stopping just short of physical contact, before repeating the process by running from a longer distance.

[7] Kirk's dik-diks are concentrate selectors, feeding selectively on dicotyledonous plants that can be rapidly fermented and digested.

[4] Because of the aforementioned facts and their high food requirements, Kirk's dik-diks feed and ruminate periodically throughout day and night.

[2] Territories are marked with dung and urine that are deposited in a ritual that is performed to help maintain pair bonds.

Copulation begins with the male standing on his hind legs behind the female and waving his forelegs at an acute angle to his own body in the air over her back".

[10] Many zoos are now known to harbor hybrids between different cytotypes, with anomalous chromosome numbers and causing unexplained sterility.

[10] Examination of these individuals shows a lack of spermatogenesis in males, for example hybrids between Kirk's and Guenther's dik-diks are infertile.

[10] Dik-diks are susceptible to a myriad of predators including eagles, wildcats, jackals, caracals, leopards, hyenas, cheetahs, Cape wild dogs, honey badgers, crocodiles, pythons, lions, monitors, and humans.

[4] Nowak (1991) asserted that dik-dik are disliked by local hunters because they flush and warn larger game to the presence of humans.
