Brief SummaryRead full entry
BiologyNubian ibex reside in single sex herds of up to 20, with offspring remaining with their maternal herd for their first three years (2) (3). Mating occurs during the late summer months, especially October (2), when the strongest males fight and compete for the right to breed by pushing against each other with their horns (4). Gestation lasts about five months and the majority of young are born in March (2). A litter size of one is usual, but twins and, very rarely, triplets occur (5). Sexual maturity is reached at two to three years, and offspring then leave their natal herd. Individuals can live up to 17 years (2). This diurnal species is active during the day and rests by night. The light, shiny coat is thought to help reflect incoming solar radiation, which allows the animal to remain active throughout the day, even during hot summer afternoons (2). The Nubian ibex is extremely agile, often maneuvering down steep, precipitous terrain to graze on grasses and leaves during the day, and later returning to the cliffs at night (2) (3). The main predators of the ibex are leopards, eagles and bearded vultures (2). When threatened, individuals will rise up on their very strong hind legs and point their powerful-looking horns towards their predator (3).
