The black wildebeest is a gregarious animal with a complex social structure comprising three distinct groups, the female herds consisting of adult females and their young, the bachelor herds consisting only of yearlings and older males, and territorial bulls.
Male black wildebeest have been reported to mate with female blue wildebeest and vice versa. [26] The differences in social behaviour and habitats have historically prevented interspecific hybridisation between the species, but hybridisation may occur when they are both confined within the same area.
The blue wildebeest (Connochaetes taurinus), also called the common wildebeest, white-bearded gnu or brindled gnu, is a large antelope and one of the two species of wildebeest. It is placed in the genus Connochaetes and family Bovidae, and has a close taxonomic relationship with the black wildebeest. The blue wildebeest is known to have five ...
The subfamily Alcelaphinae (or tribe Alcelaphini), [1] [2] of the family Bovidae, contains the wildebeest, tsessebe, topi, hartebeest, blesbok and bontebok, and several other related species. Depending on the classification, there are 6–10 species placed in four genera, although Beatragus is sometimes considered a subgenus of Damaliscus ...
Male gazelle mounting a female Fawn hiding in the grass. A male gazelle follows a female and sniffs her urine to find out if she is in estrus, a process known as the Flehmen response. [24] If so, he continues to court and mount her. [23] Females leave the herd to give birth to single fawns after a five- to six-month gestation period. [25]
The 146 extant species of Bovidae are split into 53 genera within 9 subfamilies: Aepycerotinae, or the impala; Alcelaphinae, containing the bontebok, hartebeest, wildebeest, and relatives; Antilopinae, containing several antelope, gazelles, and relatives; Bovinae, containing cattle, buffalos, bison, and other antelopes; Caprinae, containing ...
Two subspecies are recognised—the grassland-dwelling common impala (sometimes referred to as the Kenyan impala), and the larger and darker black-faced impala, which lives in slightly more arid, scrubland environments. The impala reaches 70–92 cm (28–36 in) at the shoulder and weighs 40–76 kg (88–168 lb).
With a distance between the tips of its horns of around 1.2 m (3 ft 11 in), [4] Megalotragus is probably the largest alcelaphine bovid ever recorded, [5] much bigger than the extant wildebeest. [6] The skull of Megalotragus is similar to that of the hartebeest : characterized by extreme elongation, and the fusion and posterior placement of the ...
