00:08An ecological gem shines in the heart of Europe.
00:16A wild island in the middle of a man-made landscape.
00:26But this is no ordinary nature reserve.
00:33Originating in a wastewater area, it has become essential for migratory birds from Africa, Asia and...
00:43Europe.
01:00There is a mysterious underwater world in northwestern Germany.
01:06The Munster bird sanctuary, Rieselfelder.
01:15The vast wetland is home to numerous endangered species.
01:21And today it is internationally recognized for its remarkable diversity of birds and fauna.
01:31Hidden in the dense swampy vegetation, three hungry harrier chicks anxiously await their parents.
01:41Their nest is a fortress against predators.
01:48The marsh harrier rarely breeds successfully in this region.
01:56However, this couple succeeded.
01:59And the male's last hunt was also successful.
02:04And he skillfully hands it over to his partner.
02:08They make an excellent team.
02:12Initially, only the male hunts, while the female feeds the offspring.
02:18But the offspring will soon be so large and so hungry that both parents will have to hunt.
02:30For now, temperatures are mild.
02:33But when things start to get colder, the harriers will head south to Europe or Africa.
02:44Fifty years ago, this species was practically extinct.
02:50Now, this couple is thriving.
02:53In an absolutely unexpected place.
03:05Viewed from the air, this landscape looks like a chessboard of water and reeds.
03:13However, this wild paradise did not arise naturally.
03:18It was created by man.
03:23It all began in the city of Munster.
03:30In the 19th century, it was home to 60 thousand inhabitants.
03:40As in many cities of that time,
03:43Their wastewater flowed directly into the adjacent rivers.
03:49Producing an unbearable stench.
03:51And diseases.
03:57To ease the rivers, a little over a century ago,
04:00The city began directing the waste to a network of pipelines.
04:09The sandy soil of the nearby moor acted as a filter.
04:16The suspended matter remained on the surface.
04:19as the now clean water seeped into the ground.
04:25This natural wastewater treatment plant,
04:28with an area larger than a thousand football fields,
04:32It purified the water for the entire city.
04:38And along the way, something magical and unexpected happened.
04:46A new wetland emerged from the landscape.
04:50attracting waterfowl from all over the world.
04:54Here, rare wading birds found refuge.
04:57at a time when other wetlands in Europe were disappearing
05:01for agricultural and urban development.
05:04Biologists have begun cataloging the new birds and fauna of the revitalized region.
05:13At the time, the young scientists didn't realize it.
05:16of the importance that their efforts would have.
05:28This spotted-backed curlew has returned from its winter home.
05:32south of the Sar.
05:38Like many other aquatic birds,
05:41They come to Arrisselfelder to strengthen themselves,
05:45before continuing on to the nesting areas
05:47in Scandinavia and Russia.
05:53The common snipe and the rare long-billed snipe.
05:57They also stop here.
05:59On his grueling journeys between Africa,
06:02Southern Europe and Siberia.
06:08But the achievements of this beautiful species are unparalleled.
06:15The fighter is the ultramarathon runner of the bird world.
06:20Ornithologists have even found a specimen from these parts in Eastern Siberia.
06:25more than 7,000 kilometers.
06:31without these interior wetlands,
06:34Many migratory birds would have difficulty carrying out their journeys.
06:38until the end.
06:40The fat reserves that accumulate here fuel their long flights.
07:00The remaining birds are also particularly active in the spring.
07:09Many species are now returning to nest.
07:19Wherever we look, there are matings happening.
07:45In the extensive reed beds, there are now few songbirds.
07:56For decades, the blue-breasted robin was on the verge of extinction in Central Europe.
08:03Now, he's back.
08:07The male's song establishes the pair's territory.
08:18In spring, the reeds are still brown and dry.
08:22The sun's intensity will soon change that.
08:34A pair of white storks returned from their wintering grounds in the Mediterranean.
08:40With their characteristic noise, they return to reclaim their nest.
08:47Over the next few weeks, this farm on the edge of the Nature Reserve will be your home.
08:57No other European bird builds nests this large.
09:03Some weigh up to two tons.
09:11Generally, white storks remain monogamous for many years.
09:16But they don't hesitate to change partners.
09:20In reality, they are more loyal to their nest than to their mate.
09:31The female will soon lay eggs, which both will care for for a month.
09:47Little by little, the nature reserve is emerging from hibernation.
09:57Wherever the sun touches, nature awakens.
10:08Unlike the white stork, the common coot spent the winter here.
10:19For them too, an exciting phase begins now.
10:30They fight fiercely for the best locations for modification.
10:36And they scare away any intruders.
10:57This wild goose is too big.
11:01They let him stay.
11:15The galley slaves fight until exhaustion.
11:33Today, as is almost always the case, the conflicts only end at nightfall.
12:07HE LEAVES
12:09At night, the birds take refuge in these waters.
12:15Safety is everything.
12:29Those who are not careful are lost.
12:38A fox caught a goose.
12:52It's not just your life that depends on a successful hunt.
13:01Next to his burrow, two lively juveniles await his return.
13:10They are only a few weeks old, but they are increasingly eager to explore.
13:20The reserve is a good hunting ground for foxes.
13:24The timid predator does its part to maintain the balance of nature.
13:36Not all environmentalists welcome foxes.
13:42But, in this abundant environment created by man,
13:45This family will not be the one to make a mark on the bird population.
14:06The floodplains around the lakes are not only home to foxes.
14:15The reserve is also inhabited by large herbivores.
14:26Cattle also live here.
14:28since they are particularly resistant to cold.
14:36The calves are born outdoors.
14:38and the herd is completely independent,
14:41except when it needs to be fed in winter.
14:47They are related to primitive cattle, many of them red.
14:50and their constant grazing prevents the floodplains from growing excessively.
15:00Thus, without knowing it,
15:02These cattle ensure the survival of many mammals.
15:06Rieselfelder's birds and insects.
15:16In the shallow waters warmed by the spring sun,
15:20A curious spectacle unfolds.
15:26An amphibious dance.
15:32In the marshes,
15:34common frogs gather
15:35and green frogs.
15:39Males only have one thing on their minds.
15:47Finding the ideal partner.
15:56Now is neither the time nor the place for excuses.
16:10Not even for distractions.
16:19Only males have vocal sacs.
16:25This female will not be laying eggs anytime soon.
16:39Dragonflies are also in mating season.
16:45There are almost 30 different species in this ecosystem.
16:53Their courtship is a little less clumsy than that of frogs.
16:58But they are taking risks.
17:01The barrier between happiness and certain death lurks.
17:14The barrier between happiness and certain death lurks.
17:17The barrier between happiness and certain death lurks.
17:22And the fault that the fault that the fault that the fault takes away.
17:27The barrier between happiness and one's mother.
17:56Once again, a frog misses its target.
18:17The day dawns and the male stork searches for food.
18:27The female awaits his return.
18:33And she's not alone.
18:40Four chicks are now huddled together in the nest.
18:45They are hungry.
18:47They are always hungry.
19:00For years, ornithologists have tried to attract these majestic birds with nesting aids in the protected area.
19:11It was only at the beginning of the millennium that they accepted the invitation.
19:19Today, every year, up to seven pairs nest in Rieselfelder.
19:26Some even stay all year round.
19:35In these fertile floodplains, they find the insects, amphibians, and rodents they need to feed their young.
19:52A quick look beyond this protected area reveals the importance of this restored landscape.
20:01Little wildlife survives in these agricultural fields.
20:16Across Germany, intensive monocultures are causing soil atrophy.
20:28Fertilizers spread on the soil release nitrogen into the landscape.
20:34Later infiltrated by the rains, into the water table.
20:41This imbalance poses a threat to the ecosystem and to much of the resident wildlife.
20:56Making the Rieselfelder wetland even more important is its role as a refuge for numerous species.
21:17Hidden among the reeds, this female little reed warbler has built a nest for her family.
21:25She laid four eggs, which were incubated by both parents.
21:33A familiar model that doesn't work for everyone.
21:39This female cuckoo has long since discovered the nursery.
21:48Timing is everything.
21:51You have to put the egg in the nest so that its chick hatches before the nightingales.
22:07The little nightingales in the reeds have no idea what's coming.
22:15The female checks the nest, but doesn't seem to notice anything unusual.
22:23Because they are such devoted parents, cuckoos often choose this species to care for their young.
22:30The scam worked again.
22:44The dense reed bed hides many secrets.
22:53A shy grass snake with a collar advances into the impenetrable tangle.
23:01Here it hunts amphibians, small mammals, and birds.
23:20But the duck is safe.
23:25The snake does not yet pose a danger.
23:29It has just been born and is no bigger than a pencil.
23:34An adult can reach one and a half meters in length and live up to 20 years.
23:45She was the first to hatch from the egg.
23:54There are still about 30 struggling with their leathery bark.
24:04They cut it with a special tooth designed for that purpose.
24:16They have been incubated for eight weeks by the heat of the decomposing reeds.
24:36The little ones are born fully formed and independent.
24:56In this humid environment, food is plentiful.
25:06Once they grow up, frogs will be their favorite snack.
25:25It looks like this one will need some more training.
25:36Frogs and water snakes thrive.
25:39Because there are no more untreated sewage flowing here.
25:49Now there is a large complex for this purpose, right next to the reserve.
25:59The modern Munster Wastewater Treatment Plant was opened in 1975.
26:06The old sewer system is being decommissioned.
26:18The original plan included draining the lakes to make way for a new industrial zone.
26:29However, the population was completely opposed.
26:34Biologists had witnessed the transformation of the region and were calling for a bird sanctuary.
26:42And with strong public support, environmentalists managed to save this small natural area.
26:50Instead of disappearing under the knob, Rieselfelder became a world-renowned reserve for wading and waterfowl.
27:05Today, there is clear water in these lakes and ponds, where fish such as ganagata can now thrive.
27:19When the water reaches a certain temperature, the male's belly turns red and he begins to build the nest.
27:30He's trying to impress a female, but he's not the only one.
27:43There is a rival targeting the construction materials market.
27:52The two males confront each other.
28:05It will all come down to who builds the best nest.
28:25They both give it their all.
28:49Now, the female will decide who comes out victorious.
29:08From his hiding place, he watched his rivals at work.
29:14A few final touches.
29:20She presents her belly to the male, which is full of eggs.
29:26A decision is approaching.
29:30But which one should it be?
29:39Finally, he chose.
29:43With a zigzag dance, the male guides her towards his nest.
30:02It stimulates spawning so that it can fertilize the eggs.
30:17The litter will now be the male's responsibility.
30:21And the female continues on her way.
30:28The offspring will take seven to twelve days to hatch.
30:35It is a period of impatience and waiting for the parent.
30:44Even on the surface, the new generation is the center of attention.
30:53The common coots, which in spring fought so hard over their territory,
30:58They now have two offspring.
31:07Juveniles delight in small freshwater shrimp.
31:20The small lake is its nursery, its kingdom, and its pantry.
31:32Coots can have up to ten offspring.
31:36But, as a general rule, only a few survive.
31:43These curious little creatures are easy prey for rats, birds, and predatory fish.
31:51They will only learn to fly and become independent at eight weeks of age.
32:00However, shortly afterwards, like their parents,
32:03They will become warriors, fighting over the best nesting sites.
32:15During the summer months, danger lurks in the trees.
32:23These are oak processionary caterpillars.
32:28Its long hairs are bristled at the ends.
32:32and its bite can cause allergic reactions in humans.
32:40These caterpillars multiply explosively.
32:44and, while searching for food,
32:46They can form processions up to ten meters long.
32:55Before they transform into pupae,
32:57They gather in a huge nest.
33:04After a few weeks,
33:06The nymphs appear in the form of moths.
33:11Their irritating hairs are left behind on the tree bark.
33:15where they will remain for years.
33:22The oak processionary moth is harmless to the white stork.
33:33The chicks have already started exercising their wings to fly.
33:43All four survived the summer.
33:45But soon they will be too big for the nest.
33:54It's time to risk independence.
34:10The sisters are impressed.
34:13even though she only reaches the nearest meadow.
34:19Before temperatures drop,
34:22The young storks will leave for southern Spain.
34:24and for North Africa,
34:29where they will remain until they reach sexual maturity.
34:32around the age of four.
34:37Perhaps one day she too will nest in these floodplains.
34:42Or perhaps he will choose another location.
34:50Until then,
34:51The young stork has a lot to learn.
35:03For example,
35:05who is a friend
35:05And who is the enemy?
35:17This region is clean and restored.
35:20It also witnessed the return of many local species.
35:27And also to the arrival of some from distant habitats.
35:35The coipu, or false otter,
35:38It originates from South America.
35:41They are common from Brazil to northern Argentina.
35:47They live there in very similar swamps.
35:50to this man-made wetland.
35:54The coipus were brought to Europe.
35:57for breeding on farms for the production of hides,
36:00But they quickly found a niche in nature.
36:05And now the temperatures are becoming milder.
36:08due to climate change,
36:10more and more coipus
36:11They survive the winters of Central Europe.
36:21It's an exciting time for the little reed warbler.
36:25Just 12 days after laying the eggs,
36:27There is movement in the nest.
36:36A baby was born.
36:39But what are you doing?
36:48The little cuckoo reveals itself.
36:52Under the gaze of the confused pair of nightingales.
36:59Instead of raising four of their own offspring,
37:02They are now creating an intruder.
37:08He managed to get the nightingales to adopt him.
37:13Cuckoo chicks need more food.
37:16than those of the small nightingale of the reeds.
37:20Due to its persistent calling,
37:22The nightingales believe there are several chicks in the nest.
37:25and they hurry to hunt insects for their demanding guest.
37:38It's hard work for the nightingales.
37:42But the couple fed it devotedly as if the cub were their own.
37:54Even after the cuckoo has become too big for the nest,
37:58The nightingales continue to feed him.
38:08Once again, the female cuckoo was spared.
38:11to the difficult task of creating your own proof.
38:22This vast flooded area has more than 90 lakes and ponds.
38:28some of which dry out in the summer.
38:36Among them, the vast floodplains are home to countless insects.
38:49In the dense reed bed, a wasp spider spun its web.
39:04He hopes to catch a grasshopper.
39:07But instead, it caught the attention of a male.
39:13It is only one-sixth the size of the female.
39:19He tries to seduce her with his rhythmic beats.
39:32Fortunately for him, she shows no interest.
39:36If they married her, it could mean her death.
39:44Female wasp spiders are common.
39:46They eat their partner during mating.
39:54The rich meadows of the reserve do not develop on their own.
40:07This paradise created by human hands.
40:10It continues to depend on us.
40:28Every year, after the birds have hatched.
40:30that nest on the ground leave the nest,
40:33The meadows of Rieselfelder are trimmed.
40:39Strips of tall grass are left,
40:41allowing insects and small animals
40:44to take refuge from the blinding machine.
40:49The sound of the vehicle indicates to the regular tow truck
40:52and to other species, it is lunchtime.
41:02The stork hunts frightened insects.
41:04in the harvested grass.
41:08Grasshoppers and butterflies abound.
41:19A ready-made meal for a hungry stork.
41:31With its long beak, it searches among the stems.
41:46The noise of the tractor attracts storks from all over the protected area.
42:04Conflict is inevitable.
42:24And if luck smiles upon some...
42:32It's natural that it attracts attention.
42:52The best thing to do is find a quieter place.
43:03The annual harvest turns over the nutrient-poor soil.
43:08Without it, habitat diversity could be lost.
43:12this protected zone.
43:24It's the peak of summer.
43:29For weeks, the young red-headed harriers of the Pauís
43:33They only see this square meter.
43:41And they are finally ready to leave the nest.
43:45But what to do with wings that big?
43:59It seems they will have to stay with their parents.
44:01for a while longer.
44:06They continue to bring food regularly.
44:09but they rarely feed their young directly anymore.
44:19With deliveries so fast,
44:22Sometimes they miss the target.
44:37Thanks to their dedicated parents,
44:39They are all well fed.
44:42They are resilient.
44:43And their dense plumage protects them from the elements.
