Kirk’s Dik-Dik vs Gunther’s Dik-Dik: Taxonomy, Size and Field Identification
The dik-dik and Gunther’s dik-dik being the two East African species encountered on the Tanzania and Kenya safari circuit] is the smallest antelope consistently encountered on the game drive — the Kirk’s dik-dik at 3.5 to 6 kilograms and 35 to 45 centimeter shoulder height, the Gunther’s dik-dik at 3.2 to 5.8 kilograms and 32 to 42 centimeters, both species small enough to pass under the lowest-hanging Acacia branch without ducking and fast enough to outrun the average domestic cat over the 100-meter distance. Field identification of the two species: Kirk’s dik-dik : the longer pre-orbital gland , the reddish-brown to grizzled-grey coat , the white orbital ring and the distinctive elongated, flexible nose . Gunther’s dik-dik : the shorter pre-orbital gland , the paler, more uniform sandy-grey coat , and the slightly more upright posture at rest .
Dik-Dik Monogamy: the Lifelong Pair Bond, Territory Demarcation and Dung Middens
The Kirk’s dik-dik’s social system is the most thoroughly studied monogamous antelope social system in East Africa : the Kirk’s dik-dik is one of only 3 to 5 percent of mammal species forming a lifelong monogamous pair bond . The territory demarcation: the dik-dik pair’s most active territorial behavior is the communal dung midden ; and the combined pre-orbital and interdigital gland marking . The dik-dik male’s horn: uniquely among the Kirk’s dik-dik, only the male has horns — the male’s horns at 3.5 to 11 centimeters , the horns heavily ribbed at the base and used in the “horn-to-neck” combat with rival males and the “alarm-snort” sprint .
Dik-Dik Feeding Ecology: the Browser-Gleaner, the Dew Drinker and the Water-Independent Physiology
The Kirk’s dik-dik’s diet is the most specialized of the East African small antelopes — the exclusive browser-gleaner . The dik-dik’s preferred browse species : the Acacia tortilis leaf ; the Commiphora leaf and unripe seed pod ; and the Grewia and Cordia fruits . Water independence: the Kirk’s dik-dik is independent of free water , and from the dew and mist droplets on vegetation surfaces .
Best Dik-Dik Viewing 2027: Tarangire, Amboseli and Samburu
The 2027 dik-dik safari guide: Kirk’s dik-dik is the East African safari circuit’s most ubiquitous small antelope — the species’ extremely high density and the territorial pair’s tendency to remain in a small fixed territory producing the most reliable repeat-view wildlife experience in the Tanzania and Kenya safari circuit. Tanzania 2027 — best dik-dik sites: Tarangire National Park ; Ngorongoro Crater ; and the Serengeti’s Western Corridor and Seronera Valley’s Acacia woodland . Kenya 2027 — best dik-dik sites: Amboseli National Park’s Ol Tukai acacia woodland zone ; Tsavo West National Park’s Rhino Valley and Ngulia sector ; and Samburu-Buffalo Springs and the Kirk’s being a practical field ornithology-style challenge that bird-listing visitors extend naturally to the mammal-listing mindset].
