00:00Every year, across every continent and ocean, millions of animals embark on incredible journeys.
00:07They move with purpose, driven by ancient instincts, guided by nature's signals.
00:13These journeys are known as migrations.
00:16From the skies above to the deepest oceans, migration is one of the greatest wonders in
00:20the animal world.
00:22It is a journey for food, for life, for survival.
00:26Animals do not migrate for fun.
00:28They move because they have to.
00:30Their lives depend on it.
00:32Some are escaping the freezing grip of winter.
00:35Others are chasing the rains to greener lands.
00:38Many are on their way to give birth or lay eggs in places where their young will be safer.
00:43Some animals are simply following food, knowing that if they stay where they are, they will
00:48starve.
00:49The reasons may vary, but the goal is always the same survival.
00:54Birds are the most well-known travelers.
00:56They take to the skies in great numbers, often flying thousands of kilometers.
01:02The Arctic tern is a tiny bird, but it holds the record for the longest migration of any
01:07animal on Earth.
01:09It travels from the icy north of the Arctic all the way to the frozen seas of the Antarctic
01:14and back again every year.
01:17That's a round trip of more than 70,000 kilometers.
01:21Swallows, cranes, geese, and storks also fly long distances.
01:26They use the stars, the sun, and even Earth's magnetic field to guide them.
01:32Without a map, without ever being taught, they find their way to places they have never seen
01:37before.
01:38Some mammals also undertake incredible journeys.
01:41In the Arctic tundra, herds of caribou move across the snow-covered land in search of food
01:47and safe grounds to raise their young.
01:49Their hooves crunch on the frozen ground as they walk for hundreds of kilometers through
01:54biting cold and deep snow.
01:56In the oceans, humpback whales swim thousands of kilometers from cold polar waters to warm
02:02tropical seas to give birth.
02:04These gentle giants rely on the rhythm of the seasons to tell them when it is time to
02:08go.
02:09Bats, the only flying mammals, also migrate.
02:13Some travel hundreds of kilometers to find warmer places where they can spend the winter
02:18in deep sleep, known as hibernation.
02:21Beneath the surface of rivers and oceans, fish follow ancient paths.
02:26Salmon are born in freshwater rivers.
02:28As they grow, they swim downstream to the open ocean where they spend most of their lives.
02:34But when the time comes to reproduce, something calls them home.
02:38They return to the very river where they were born.
02:41It is a journey full of dangers.
02:44They must swim against strong currents, leap up waterfalls, and avoid hungry predators.
02:50Many do not survive the journey, but those that do give life to a new generation.
02:55Most believe they find their way using their strong sense of smell, remembering the scent
03:00of their birth river even after years in the ocean.
03:04Even small creatures like insects take part in migration.
03:08Monarch butterflies with their delicate wings travel over 4,000 kilometers from Canada to Mexico.
03:14It is a journey so long that no single butterfly makes it all the way.
03:19Instead, it takes several generations to complete the round trip.
03:24The butterflies that return are the grandchildren or even great-grandchildren of those that began
03:29the journey.
03:30Yet they follow the same path as if the map of their route is written in their blood.
03:35Migration is not an easy journey.
03:38Along the way, animals face many challenges.
03:41The distance itself can be exhausting.
03:44Food and water may be hard to find.
03:46The weather can turn suddenly, bringing storms, strong winds, snow, or heat.
03:52Predators wait along the way, ready to catch the tired or the weak.
03:57Human activities have made things worse.
03:59Roads, cities, and fences block migration paths.
04:04Pollution harms the animals and the places they depend on.
04:07Climate change is shifting the timing of seasons.
04:10Plants may bloom too early or rivers may dry up too soon.
04:15Those that arrive late may find that there is no food left.
04:18Yet even with all these dangers, animals still migrate.
04:22They move with determination.
04:25They move as their ancestors did.
04:27And in doing so, they play a vital role in keeping nature in balance.
04:32Migration helps spread plants and seeds.
04:34It moves nutrients across great distances.
04:37For example, when salmon return to rivers and die after laying eggs, their bodies feed other
04:43animals and enrich the soil.
04:46Birds and bats carry seeds to new places, helping forests and grasslands grow.
04:51By moving from place to place, animals also prevent overgrazing and help reduce disease.
04:57The mystery of how animals find their way still puzzles scientists.
05:01Some follow the sun during the day and the stars at night.
05:05Others seem to feel the Earth's magnetic field like a built-in compass.
05:10Some remember the shape of coastlines, mountains, and rivers.
05:14Others use their sense of smell or hearing.
05:17What is even more amazing is that many young animals migrate without ever being shown the way.
05:23It is as if nature has ridden the path into their very bones.
05:28Animal migration is a powerful reminder of how deeply all life is connected.
05:33The journey of a single bird or fish may affect an entire ecosystem.
05:37When we protect migration routes, we protect not just the animals, but the lands and waters
05:42they travel through.
05:44People around the world are working to help.
05:47Wildlife crossings are built over roads.
05:50Wetlands are restored.
05:51Birds and flowers are planted for birds and butterflies.
05:55Protected areas are created to keep migration paths open and safe.
06:00By learning more about these animals and their journeys, we can help ensure they continue for
06:04generations to come.
06:06There is something beautiful and inspiring about migration.
06:10It is a story of movement, of courage, of endurance.
06:14It is a journey of life and survival that has gone on for millions of years.
06:19From the beating wings of a butterfly to the steady swim of a whale, each step of the journey
06:24is a miracle of nature.
06:27These travelers remind us of the wonders of the natural world.
06:31They show us that even the smallest creature can travel great distances.
06:35They teach us that every journey, no matter how long or difficult, is worth taking.
