THE ANIMAL FILES

Sable antelope

Hippotragus niger

A dark bull and a brown youngster can belong to the same antelope species.

Sable antelopes have robust bodies, neck manes and backward-curving ringed horns. Coat colour changes with age and sex, while groups include females, calves and breeding males with different roles. They feed on vegetation in savanna landscapes.[1]

Black is not every life stage

Mature males commonly darken toward black, while females and juveniles are often brown or chestnut. Southern females can also be very dark. Pale facial markings and underparts contrast with the darker body. Colour alone therefore cannot provide a universal rule for sexing an unfamiliar individual.[1]

Horns and social change

Both sexes have long, ringed horns sweeping backwards. Young males leave female groups and may associate in bachelor groups before gaining breeding opportunities. Female groups can divide when they become large. The presence of horns does not identify a bull, and the presence of several animals does not tell you their age or breeding status.[1]

Plant food and mineral visits

Grasses, leaves and other plants provide food, with reduced activity during the hottest part of the day. Animals visit salt licks and may chew bones for minerals. Mineral-seeking does not make them routine meat-eaters; it is a different use of material from the grazing and browsing that supplies most food.[1]

A COMMON MIX-UP

Are horns restricted to adult males?

No. Females also have ringed, backward-curving horns.[1]

TRY A LITTLE REASONING

Why could a photograph of a brown calf mislead someone using only the name “sable”?

Reveal the explanation

The coat changes during development; adult male darkness is not the colour of every age and sex.[1]
