(birds squawking) ♪ Other times, its endless marshes offer a home to millions of birds.

♪ When the marshes dry, the land becomes a merciless desert, a little river its only lifeline.

♪ This is the Puszta, the plains of Hungary.

One of the largest herds of wild horses on Earth found a new home in this waving sea of grass.

This is their story.

♪ (horse neighing) The young spring foxtail grass is the favorite treat of the Przewalski horses, the only truly wild horses in the world.

They're not native to the steppes of East Hungary, finding their home here only a few decades ago.

Nearly 300 of them roam these vast flatlands.

The herd is divided into smaller harems.

One stallion usually lives with several mares.

(calm music) ♪ It's May, the time when the mares give birth.

♪ Meet Dot, the hero of our story.

Barely 30 minutes old, she finds her footing.

♪ Her mother nudges the foal towards their own group.

The Puszta has no large predators, but the danger is lurking within the herd.

Aggressive young stallions may attack the foals, but they have protection.

This brown stallion is the father of the foal.

♪ It's got to be here somewhere.

♪ Nope.

She's an experienced mom.

♪ The father soon catches up and the group is together, 14 members in all.

(horses whinnying) (mellow music) ♪ The wild horses almost went extinct in their native Mongolia, but captive breeding pulled them back from the brink.

Some were brought here to Hungary's Hortobágy Natural Park.

This herd can secure the species' survival if they become endangered once again.

♪ The wild horses walk and graze endlessly.

It helps to preserve the Puszta's ancient character.

All this moving around exhausts the newborn foal.

With a belly full of warm milk, it's nice to stop and doze.

(horses whinnying) Nearby, the bachelors practice their moves.

The young stallions had no luck forming their own harems.

Their wrestling seems playful, but they pose a threat to newborn foals and can accidentally or intentionally kill them.

Back off.

Dot's father springs into action and chases the bachelors away.

(birds chirping) (bright music) ♪ In the spring, the Puszta rings with the cheerful chirps of skylarks and the grassland teems with life.

(horse neighing) The marsh harriers love to hunt among the wild horses.

Dot, just a few days old, falls asleep.

Wild horse foals just love an afternoon nap.

But the herd won't wait.

Their group has started off too, and the stallion should protect them.

Instead, he's stuck here waiting for Dot and her mother.

(solemn music) He lowers his head, signaling he would like to lead his family back to the group.

♪ But Dot's mother is a more easygoing parent.

Let the poor kid sleep.

But the quarrel awakens Dot anyway.

Help arrives.

A mare from the group seems to have a few ideas of her own about child rearing.

She makes it clear who she's siding with.

Who can sleep in all this commotion?

The stallion is nervous.

While he's occupied with Dot and her mother, a bachelor might steal his mares, but he can't abandon his foal.

He quickly herds the group together.

The lapwings can relax, the marsh harriers aren't hunting today.

They're gathering materials for their nest.

The bluish male chooses the spot, but the brown female gets the final word.

Prime marshland real estate is tough to find.

The water protects the chicks from the predators.

Their mothers show them how.

♪ And then they find their peers within the group.

♪ (horse whinnying) (birds squawking) The Puszta is more than an endless grassland.

Before agriculture tamed much of the land, oak groves dotted the plains of Hungary.

Even now, a few small woods persist, especially near the rivers.

This is the Puszta's high-rise neighborhood.

(leaves and grass rustling) The canopy has plenty of space for everyone, including the white-tailed eagle, the king of the steppes' skies.

The chicks search the sky in vain.

They've grown big now, so their parents rarely bring food, though they still keep an eye on the nest.

The tree sparrow could hardly find a safer nesting place with the eagle as his wingman.

This starling is just having a look around.

It nests lower down in the hollow of a tree.

The starlings spend their day feeding the perpetually hungry little ones.

The chicks are naked for a week.

When mom returns, she brings food and some much-needed warmth.

The temperature is dropping.

(dramatic music) ♪ When a cold front sweeps through the Puszta, nothing stands in its way.

♪ The invading cold air pushes the warmer mass higher where it cools suddenly, the recipe for a powerful storm.

♪ (rain pouring) ♪ The shore birds have nowhere to run, but no need to worry.

The black-winged stilt is sturdier than it looks.

They don't dare venture among the trees, instinctively avoiding closed spaces.

They patiently endure the rain drumming on their backs.

♪ The cooler weather has put the foals in a frolicking mood.

♪ Dot and her half sibling hang out with the other younglings, even making lifelong friends with the other harems.

♪ There's nothing to fear from the bachelors either.

Nobody can catch these speedy furballs anymore.

♪ But after burning off all that energy, the tired foals return to their own groups.

The heat and the summer showers work their magic on the Puszta.

(soft music) ♪ (crackling) ♪ The Hortobágy National Park becomes a paradise for water birds.

Even temporary waters have fish.

Mostly, they're invasive, but the hungry little egret finds them delicious just the same.

At seven grams, the tiny harvest mouse moves almost unseen among the sedge.

♪ (birds chirping) ♪ It has nothing to fear from the avocet and the black-winged stilt, or the redshank either.

They hunt crayfish and aquatic insects in the shallow waters.

(birds squawking) The modest common snipe blends into its surroundings while the egrets get busy with their beauty rituals.

In wetter years, when the water is high in the marshes, the whiskered terns nest in colonies neighboring the wild horses, just like the greylag goose, the only wild goose that nests in these plains.

The worried parents never take their eyes off the horizon.

The wild horses aren't hostile, but when the hooves of 300 thirsty animals head for the water, you'd better jump out of their way.

(wings flapping) (insects chirping) The marshes provide a nice day at the beach to relieve the summer heat.

(water splashing) The shy foal steps lightly.

The bachelors prefer to splash away from the large herd.

Time to move on.

The most experienced mares always lead the way.

♪ Water everywhere, as far as the eye can see.

One-third of the Hortobágy National Park is precious wetland.

♪ (wind blowing) (birds chirping) ♪ The male marsh harrier heads out to hunt.

♪ He's betting on the horses to flush out a small bird or a vole.

So many tasty treats.

♪ The two-week-old chicks wait impatiently for food in the safety of the reeds.

♪ Dad has finally caught a mouse.

♪ (chicks squeaking) Both parents feed the chicks, though the female always stays near the nest to protect the little ones.

But they hardly need their parents to feed them anymore.

Their beaks are sharp and they're doing pretty well on their own.

They even settle their sibling disputes.

Their father heads out to find their second course.

A stunning hunter, he flies low to the ground and reacts in a flash to the slightest movements.

The chicks await their meal, and here comes Dad, but he doesn't visit the nest.

He tosses the prey to his mate.

Then the female either feeds the chicks or eats the food herself.

♪ Lunch is cancelled today.

At least there's leftover mouse.

♪ On the salt-crusted white Puszta, the trodden paths point the way towards the watering spots.

♪ Even during a drought, the rivers still trickle.

♪ Dot awakens.

♪ Where did everybody go?

(bright music) At least she has her buddy.

♪ They hurry to join the others.

♪ Finding them just in time.

♪ The horses have a serious drinking problem.

The bank is steep, the terrain is slippery, and the water is deep.

The wild horses instinctively fear these situations.

But drink they must.

In this tense time, all it takes is one horse to recoil and panic breaks loose.

(horses whinnying) (water splashing) The crazed adults can easily trample the foals.

Dot and the others hang back.

Besides grazing, they still get mother's milk, so they're less thirsty.

After everyone's had their fill, the herd starts back.

(upbeat music) ♪ But it's hard to resist a dust bath.

The Przewalski's horses can stand the cold, but the icy snow that sticks to their hooves makes walking a struggle.
