The LBV draws attention to a fascinating natural spectacle.

Cranes have been sighted in Bavaria, and the birds are currently also migrating across the district.

  • Cranes sighted over the Zellbach valley

  • Migratory birds fly along the Isar

  • The crane is considered a "lucky bird"

Dietramszell -

On Tuesday, cranes were sighted in northern Bavaria, and since Wednesday they have been flying over our district.

The migratory bird, trumpeting loudly, is currently on its way to its winter quarters.

In Europe and Germany the migration of the cranes is in full swing.

"Migrating cranes can also be seen and heard in many places over Bavaria," shares Dr.

Miriam Hansbauer, crane expert at the State Association for Bird Protection (LBV).

"Especially in northern Bavaria, some crane troops of up to 200 birds have been observed in the last few days, migrating from east-northeast to west-southwest." The aim is for the birds to roost in southwestern Europe and North Africa.

The LBV therefore expects more migrating cranes in the sky over Bavaria in the coming days.

The route between the northern edge of the Alps and the Danube has been used by Eastern European cranes for ten years now, coming from the largest European resting place in the Hortobágy National Park in Hungary.

Birds orientate themselves on rivers and mountain peaks

The large birds currently observed over Bavaria come from Hungary via Austria via the Baltic-Hungarian migration route.

You cross southern Bavaria in a west-southwest direction and continue flying along the Alps before finally resting in the Camargue in southern France.

Why this new train route has become so established cannot be clearly explained and is related to many factors.

A decisive factor: "Cranes are very flexible and no genetically fixed migration routes are inherited," explains Hansbauer.

Experts also assume that a general expansion of the breeding area and climate change will have a significant influence.

"It is now known that experienced adult birds pass on information about migration routes and can thus induce other cranes to move with them on new paths," the LBV crane expert continues.

The animals orient themselves on landmarks such as rivers and mountain peaks as they migrate.

They prefer to pull in high pressure weather.

Then the easterly winds carry them and the birds save strength.

In the typical V formation, the strong and experienced animals fly at the top, followed by families with an average of two young animals.

If the flight conditions are favorable, the animals, which are up to 1.30 meters tall, can fly to southern Europe without stopping at a speed of 50 to 70 kilometers per hour.

"Experience over the past few years has shown that most cranes migrate through Bavaria between mid-October and mid-November," adds Hansbauer.

Expert tip: Keep your head up and your ears perky

On Wednesday LBV trainee Regina Mannhart and LBV forest manager Birgit Weis sighted the migratory birds in the district.

They saw 52 cranes above the Zellbachtal nature reserve near Bairawies.

"We became aware of the concise trumpet-shaped calls," said Weis from the LBV district group.

The cranes move along the Isar to their next resting place.

If you want to enjoy this autumn spectacle, the conservationists recommend: Keep your head up and ears perk up.

According to the LBV, the fact that cranes can be seen again over Bavaria is due to decades of protection efforts, through which the populations throughout Europe have recovered.

The bird, revered as the "lucky bird" in many countries, is now represented in Bavaria again with at least 20 breeding pairs, most of them in the Upper Palatinate.
