Every year, one of the most exciting events in the animal world takes place in East Africa, the Great Wildebeest Migration. This amazing journey involves over 1.5 million wildebeests, along with thousands of zebras and gazelles.
They travel in a big circle between Tanzania and Kenya, searching for fresh grass and water. But one of the most special parts of this journey is the wildebeest calving season, when thousands of baby wildebeests are born in just a few weeks.
The calving season happens once a year and is a very important part of the migration. This is when mother wildebeests give birth to their calves. Around 8,000 babies are born each day during this time.
This incredible event takes place between January and March in the Ndutu plains, which are part of the Ngorongoro Conservation Area and the southern Serengeti in Tanzania. These areas have short green grass that is perfect for baby wildebeests to stand and run soon after birth.
If you have ever wanted to witness raw wildlife moments in real life, then keep reading, as this guide will tell you everything you need to know about the wildebeest migration calving season.
What is the Wildebeest Calving Season?
The wildebeest calving season is a short but very important time when thousands of wildebeest mothers give birth to their babies in the wild. This birthing season usually takes place from January to March, during the early months of the year.
It mainly happens in the Ndutu region of the southern Serengeti and the Ngorongoro Conservation Area in Tanzania. During this time, the land is full of life as over 500,000 baby wildebeests are born in just a few weeks.
The reason this season happens in January to March is because of the short rains that fall in this area around November and December. These rains make the grass grow fresh and green, which is perfect for feeding both the mother wildebeests and their newborn calves.
One of the most amazing things about the Serengeti calving season is how synchronized the births are. Most of the baby wildebeests are born within just a 2-3 week period. This is called “synchronized birthing.”
Where Does the Calving Season Take Place?
The migration calving season takes place in one of the most special wildlife areas on Earth, which is the Southern Serengeti, especially around the Ndutu region and the nearby Ngorongoro Conservation Area in northern Tanzania.
This part of Africa is known for its wide, open grasslands that stretch as far as the eye can see. It is peaceful, green, and full of life during the rainy season, which makes it the perfect nursery for baby wildebeests.
The land here is made up of soft, short grass that grows quickly after the rains. These grasses are rich in nutrients, which help mother wildebeests stay strong and healthy while feeding their newborn calves. The open plains also make it easier to spot predators like lions and hyenas from a distance.
This gives the mothers a better chance to protect their babies during the first few critical days of life. The flat land also helps baby wildebeests stand and walk just minutes after birth.
Why is the Calving Season Crucial to Migration?
The calving season is not just about baby animals being born, infact, it plays a big role in the survival of the entire species. This season is a major part of the Great Migration cycle. Without it, the wildebeest population would not grow, and the balance of life in the Serengeti would be affected. Each new calf born helps to keep the herd strong and large enough to continue the long journey through East Africa.
This season also affects the lives of many other animals. It creates an intense predator-prey scene in the Serengeti. While thousands of wildebeest newborns take their first steps, predators like lions, cheetahs, hyenas, and jackals are never far behind.
These predators depend on this season for food, and they follow the herds closely. It might seem sad, but this is all part of the circle of life, where each animal has a role in keeping the ecosystem healthy and in balance.
That is why this season is so important, as it sets the tone for the next phases of the migration, all the way to the Mara River crossings and back again.
Wildlife Encounters During the Calving Season
This season is not just a time to see baby wildebeests, as it is also one of the best times to witness dramatic wildlife action up close. During these weeks, the southern Serengeti and Ndutu plains become full of life, which attracts many other animals.
If you go on a safari during calving season, then you are likely to see the raw power of nature and the strong connections between all creatures.
Predators play a major role during this time. Lions, cheetahs, and hyenas are some of the top hunters in the area. They follow the herds closely, knowing that wildebeest newborns are easy targets in their first days.
It is not all about predators. The calving areas are also home to many other herbivores like zebras, gazelles, and eland. These animals mostly travel with the wildebeests and help to keep the grasslands trimmed and balanced.
Plus, the rich landscape draws in lots of birds. You will see secretary birds, vultures, eagles, and colorful bee-eaters flying overhead or perched in trees. The mix of animals during this season makes it one of the best times to explore the Serengeti and experience Africa’s wildlife in action.
Best Time to Witness the Calving Season
The best time to witness the wildebeest migration calving season is from late January to early March. This short window is when most of the baby wildebeests are born across the Ndutu plains in the southern Serengeti.
If you are planning a trip, then this is the best time for a Serengeti safari to see one of nature’s greatest events, as new life enters the world, predators are on the move, and the start of the wildebeest’s journey north.
During these months, the weather in the Serengeti is warm and mild. It is the “green season,” which means the rains have made the land fresh and full of green grass. The skies are mostly clear in the mornings with occasional rain showers in the afternoon.
For many nature lovers, a wildebeest migration safari in January or February is the best way to truly experience the wild, raw beauty of Africa.

The wildebeest migration calving season is just one part of a much bigger adventure known as the Great Wildebeest Migration. Every year, nearly 2 million wildebeests, along with zebras and gazelles, move in a giant circle through Tanzania and Kenya in search of fresh grass and water.
The journey begins in January to March in the southern Serengeti, where the calving season takes place. After the baby wildebeests are born, the herds start moving northwest. By May and June, they reach the Grumeti River, where many wildebeests must cross through crocodile-filled waters. It’s a dangerous but necessary part of the migration.
Later, in July through October, the herds head north to the Mara River, located near the border of Kenya. This is one of the most famous parts of the migration because of the dramatic river crossings. Finally, from November to December, the herds return south again to start the cycle all over, just in time for the next birthing season in the Serengeti.
Final Words
The wildebeest migration calving season is a major part of the Great Migration, which brings new life to the Serengeti. From the birth of thousands of baby wildebeests to the dramatic river crossings, this season brings life to the Serengeti and offers a rare glimpse into the circle of life.
FAQ
What month along the migration do the wildebeests have their calves?
Wildebeest calves are usually born in February, during the herds’ stay in the southern Serengeti plains of Tanzania. This timing aligns with the rainy season, when grass is abundant and conditions are ideal for raising newborns.
How many calves does a wildebeest have?
A female wildebeest typically gives birth to one calf per year. Twins are extremely rare in the wild.
What is wildebeest calving?
Wildebeest calving is the annual period when thousands of wildebeest give birth almost simultaneously. It’s a remarkable natural event that happens during the Great Migration and draws countless predators and safari enthusiasts alike. Calves are usually born within a tight 2–3 week window, creating a dramatic spectacle of life and survival.
How are the wildebeest calves protected?
Wildebeest calves are protected primarily through safety in numbers. By giving birth at the same time, the herds overwhelm predators with more targets than they can hunt—this is known as the “predator swamping” strategy. In addition, calves are up and running within minutes of birth, which helps them stay with the herd and avoid being left behind.
What preys on wildebeest calves?
Common predators of wildebeest calves include lions, cheetahs, hyenas, leopards, and sometimes wild dogs and crocodiles. Calves are especially vulnerable in the first few weeks after birth.
What is the pregnancy period of the wildebeest?
The pregnancy period of a wildebeest lasts about 8 to 9 months. Most wildebeests give birth around the same time during the calving season.
How many calves are born?
It’s estimated that over 500,000 calves are born each year during the calving season. This massive birth rate is crucial for the survival of the wildebeest population, considering the number lost to predators and harsh conditions.
