Where the Great Migration actually begins
Up to 8,000 wildebeest calves are born every day on the southern Serengeti plains between January and March - and you'll have the park largely to yourself.
Half a million calves, on grass replenished by rain
Two million wildebeest move onto the southern Serengeti's fresh green plains, drawn by rain-fed grazing just as calving season begins. Over a few months, close to half a million calves are born - as many as 8,000 in a single day.
Zebra, Thomson's gazelle and eland give birth alongside them, using the wildebeest's sheer numbers as cover. Newborns stand within minutes and can run with the herd within days - skills they need immediately, with predators drawn to the scene.
Plan a calving season safari
Even the predators time their births to this season
Cheetah, hyena, jackal and wild dog also give birth now, when meat is most plentiful for their young. Mother wildebeest return to the same shorter-grass fields year after year, where approaching predators are easier to spot.
When threats appear, groups of mothers form a protective barrier around the newborns. With so many calves born at once, predators eventually eat their fill - leaving the majority of calves to survive.
Ancient volcanic ash still shapes the calving grounds
Zebra and gazelle graze down the taller grasses first, leaving shorter shoots that newborn wildebeest can actually eat - one grazer setting the table for another.
Beneath it all: thousands of years of Ngorongoro's volcanic activity enriched this soil with calcium and magnesium. Pregnant wildebeest are drawn to the resulting grasses, which help nourish their unborn calves.
Fewer crowds than July's Great Migration
The Great Migration from July to October draws the headlines and the tourists. Calving season doesn't - you'll share the plains with newborn zebra, gazelle, eland, baboons, warthogs, elephants, giraffes and litters of lion, leopard and cheetah cubs, largely undisturbed.

Calving season - your questions answered
When is wildebeest calving season?
January to March, on the southern Serengeti's short-grass plains - around six months before the Great Migration's July-October river crossings.
How many calves are born?
Close to half a million wildebeest calves over the season, with as many as 8,000 born in a single day at the peak.
Is calving season less crowded than the Migration?
Yes - the July-October Migration draws the largest crowds. Calving season offers a comparably dramatic spectacle with far fewer other vehicles around.
Will I see predators too?
Yes - cheetah, hyena, jackal and wild dog time their own births to this season, and lion, leopard and cheetah cubs are commonly spotted throughout the Serengeti.
How quickly do newborn wildebeest move?
A calf can stand within minutes of birth and run with the herd within a few days - an essential survival skill with predators nearby.
Can I add a balloon flight or village visit?
Yes - both are popular add-ons. A hot air balloon safari gives an aerial view of the calving fields, and a Maasai village visit adds cultural context to the trip.
