Plains zebra

Equus quagga

A huge zebra herd can contain many smaller, lasting groups.

Plains zebras graze in African landscapes and form stable family groups. Several such groups can gather into a much larger herd without losing their internal relationships. Their social structure therefore works at more than one scale.[1]

Stripes vary across the range

Broad black-and-white stripes change direction across the body, from more vertical on the front to more horizontal behind. Southern populations can have brown shadow stripes, and foals begin with browner dark stripes.[1]

A grazer can start with tough stems

Flexible lips guide grass toward the incisors. Zebras can use long, fibrous stems as well as fresh short growth, spending much time feeding. Their grazing can alter vegetation available to other grazing animals.[1]

Families within the moving herd

Family groups retain stable adult membership, while bachelor groups contain males outside those families. Several units may travel or gather together. Counting the full herd does not reveal how individuals organise their closest associations.[1]

A COMMON MIX-UP

Is a large herd one single family?

No. It can contain several family groups and bachelor groups, each with its own relationships.[1]

TRY A LITTLE REASONING

Why follow identified individuals during a migration?

Reveal the explanation

Repeated observations can reveal stable smaller groups that a single herd count would miss.[1]
