Animals travel in groups for many different reasons. An elephant herd may be a matriarch-led family, wolves move as a pack that teaches young how to survive, and elk gather in large seasonal herds for safety and warmth. Other species cooperate without making long journeys: meerkats take turns as sentries, beavers share a colony, and giraffe mothers use a nursery for calves.
The twelve examples below show why “travel in groups” is a broad description rather than one behavior. Some groups are families, some are colonies or temporary associations, and only some undertake seasonal migrations across large landscapes.

The 12 animals and how their groups work
1. Elephants: a matriarch-led family herd
South African National Parks describes an elephant breeding herd as related females and their young. The oldest experienced female, known as the matriarch, sets much of the herd’s activity and movement. Females can assist one another with calves, so a young elephant is surrounded by more than its mother when the group is on the move.

As males mature, they may leave the family unit and live alone for periods or form temporary bachelor groups. Elephant society therefore includes both close family travel and more independent adult lives.

2. Wolves: family packs that teach survival
A wolf pack is a family unit, according to the U.S. Fish & Wildlife Service. Within it, young wolves learn practical skills such as hunting, avoiding danger and defending themselves. Pups initially stay close to the den; as they grow, they accompany the pack farther and take part in more of its travel.
Pack membership is not necessarily lifelong. Wolves commonly disperse to find mates and establish new packs. Wolf biologist Colby Gardner compares that departure to leaving one’s hometown: a dispersing wolf enters unfamiliar territory with hazards including roads, rival packs and people. Until dispersal, however, the pack’s territory is the young wolf’s entire known world.
3. Zebras: herds that can defend an injured member
Zebra herds provide safety in numbers, but the clearest documented example is a specific response to danger. San Diego Zoo Wildlife Alliance describes herd members circling a zebra injured by a predator and defending it. Surrounding the vulnerable animal can make it harder for a predator to reach the target and gives the herd more opportunities to detect another attack.

That observation should not be stretched into a claim that every zebra herd responds identically in every encounter. It demonstrates how a herd can act collectively when one member is at immediate risk.
4. Meerkats: teamwork built around sentries and foragers
Meerkats divide useful jobs among group members. While some search for grubs and other food, another may stand upright as a sentry, watching for predators. The lookout can alert the foragers, allowing them to spend more time digging and less time scanning the sky and surrounding ground.
Sentry duty is a cooperative task rather than a sign that one permanent “guard” leads the group. Members share responsibilities, and the group’s daily movements connect safe lookout points with productive feeding areas.

5. African wild dogs: feeding the group after a hunt
African wild dogs show cooperation at both the hunt and the den. After returning from a hunt, adults may regurgitate food for group members that are ill, old or very young. That behavior lets animals that could not keep up with the hunt receive nutrition from those that did.

It links travel, food acquisition and care of dependent members, making the pack’s movement useful to the entire social group.
6. North American elk: large herds that change with the season
The National Park Service describes elk as social animals often seen in herds. In some circumstances, a herd can contain several hundred animals. Living together can make it easier to detect predators, conserve warmth and move through deep snow.
Elk do not maintain one fixed herd size throughout the year. Seasonal conditions and breeding patterns alter who travels together and how large the group becomes. A large winter aggregation and a smaller group in another season are both normal expressions of elk social behavior.
7. Beavers: family groups that can form colonies
Beaver families include adults and their offspring, and several families may live in the same colony. Cooperation extends beyond simply being nearby: members watch for predators, warn one another, gather food, build dams and care for young.
Because beavers depend on waterways and constructed habitat, their group movements are usually local rather than long-distance migrations. The colony’s shared engineering changes the place where the animals live, while shared vigilance and care reduce the risks of raising kits.
8. Black-billed magpies: flexible family associations
Black-billed magpies may remain in family groups or join other birds outside the nesting season, according to the National Park Service. During nesting, parents work together to build a nest and raise young. Outside that period, association with additional birds can provide social contact without implying that every magpie belongs to one permanent flock.
The species illustrates how group membership can expand or contract with the calendar. Family cooperation is especially important when eggs and nestlings require protection and feeding.
9. Bumble bees: a colony rather than a traveling herd
Bumble bees are social insects that live in colonies, and the National Park Service includes them among examples of local wildlife showing group behavior. A colony is a different kind of group from an elk herd: bees leave the nest on individual foraging flights and return to a shared social home.
The cited material does not establish one colony size or a single social pattern for every bumble-bee species. The reliable point is the colony-based way of life, in which individual trips support a communal nest.
10. Bonnet macaques: social groups with a shared daily life
National Geographic educational material lists bonnet macaques as animals that live in groups. That broad description matters because a macaque’s daily activities—moving between feeding places, resting and responding to threats—occur in a social setting rather than in isolation.
The cited passage does not provide a particular group size or a measured travel distance, so it is safest to describe bonnet macaques as group-living primates without assigning every troop the same structure.
11. Giraffes: nurseries that spread the work of calf care
Giraffe mothers can leave their calves in a nursery while they feed and socialize. Other mothers remain with the calves, guarding them as a group. This arrangement allows some adults to forage while others provide a watchful presence for young animals.

Nursery care is a form of group travel even when the adults are not marching in one tight herd. The mothers’ movements between feeding areas and the nursery are coordinated around the safety of the calves.
12. Emperor penguins: social living in a severe climate
National Geographic names emperor penguins among animals that live in groups. Group living is especially visible in a species that must function in an extreme environment, where staying with other penguins can organize breeding, chick care and daily activity.
The cited educational passage does not establish a particular group size or travel distance for emperor penguins. It supports the narrower conclusion that these penguins are social animals whose lives are organized around other members of their species.

There is no single advantage that applies equally to all twelve species. Group behavior can solve different problems depending on an animal’s body, habitat and social system.
- Detecting and responding to danger: More eyes and ears can improve warning. Meerkats assign sentry duty, while zebra herds have been observed defending an injured member.
- Protection through numbers: Elk herds can make predators’ choices harder and help individuals stay safer. Wolves also defend a shared territory as a pack.
- Finding and distributing food: Meerkats divide foraging and lookout tasks. African wild dogs carry the benefits of a hunt back to animals at the den.
- Warmth and difficult travel: The National Park Service identifies warmth and movement through deep snow as benefits of elk herd living.
- Raising young: Elephant females assist calves, beavers share care of offspring, giraffes use nurseries and wolf packs teach young essential survival skills.
- Shared construction and maintenance: Beaver colonies cooperate on dams and food collection, altering and defending the habitat they depend on.
These benefits come with costs, including competition for food, the need to share space and a greater chance of attracting attention. The examples show adaptations to particular circumstances, not a universal rule that larger groups are always better.

Group travel is not the same as migration
Living or moving together locally is different from seasonal migration. Migration is a repeated movement between areas, usually tied to seasonal access to food, breeding habitat or other resources. The Convention on the Conservation of Migratory Species of Wild Animals identifies seasonal migrations that sustain large herds, including Serengeti wildebeest, Arctic caribou, Mongolian gazelle, white-eared kob and African elephants.
Migration also depends on connected landscapes. The convention’s migration atlas maps corridors and locations where routes intersect roads or railways, showing why a route can be essential even when it is not occupied year-round. A species can therefore be highly social without being a long-distance migrant, while a migratory species may spend only part of the year in a conspicuous group.
One often-quoted scale comes from the National Geographic Society’s 2020 Young Explorer teacher guide, which states that “a wildebeest herd can number up to a million.” That is the guide’s stated upper figure, not a current census estimate. It conveys the potential scale of a migration while leaving the twelve examples above in their proper context: some travel seasonally, and others simply coordinate daily life in family groups, colonies or herds.
What changes a group’s size and membership?
Age, season and social roles all matter. Young wolves eventually disperse; male elephants may leave breeding herds; elk herd size shifts through the year; and magpies may associate with additional birds outside nesting season. A group seen in one month or at one life stage should not automatically be treated as the species’ permanent arrangement.
Researchers and wildlife managers also describe groups using different words—pack, herd, colony, family group or nursery—because the underlying relationships differ. Those labels are useful only when paired with what the animals actually do together: guard, forage, build, teach, feed or migrate.
Key takeaway
The animals that travel in groups do not share one strategy. Elephants and wolves organize movement around family, beavers around colony cooperation, meerkats around rotating jobs, and giraffes around shared calf care. Seasonal migration is a more specific pattern that applies to some herd-forming species, not to every social animal. The best way to understand a group is to ask what its members accomplish together and how membership changes over time.
