Natural spectacle of blue frogs in spring

During the mating season, moor frog males turn blue for a short time

    Blue moor frogs - a nature show in Lüneburg Heath

    For moor frogs, the mating season has started.

    The males turn blue – a nature show that you should not miss. Every year thousands of visitors flock to the bogs of Lüneburg Heath for this natural spectacle.


    When and where?


    In March and April, you can experience a truly blue wonder at "Pietzmoor" near Schneverdingen in Lüneburg Heath Nature Park, at "Schäfermoor" in Südheide Nature Park, and in the NABU Biotope near Molbath in Uelzen district.


    It is the mating season of the protected moor frogs (Rana arvalis), which find ideal living conditions in both bogs. The special feature of mating frogs' mating season is the almost complete blue colouration of the males to increase their attractiveness to the female.


    This may be the only time in nature that the females are delighted when the males are blue. But beware: the frogs are only active in the sunshine.

    What distinguishes the blue moor frog?

    The moor frog belongs to the genus of "real frogs" with a size of 5-6 centimetres. On the upper side, both the male and the female are usually light brown to dark brown. The body is quite slim and the frog mouth is short and pointed.

    The male turns blue

    During the spawning season in March and April, the moor frog males change their appearance. They take on an intense blue colour with increasing courtship activity to impress the females. This blue usually lasts only a few days.

    Mating call of blue moor frogs

    Moor frogs' mating call is like a "blubb" of an empty bottle kept under water. Normally, several males gather in shallow water to form a frog chorus. The frog concert can be heard during the day and at night. Moor frogs are loud, especially in sunshine. On average, a moor frog lays about 500 to 3,000 eggs during spawning time.

    Bogs in Lüneburg Heath – ideal for the moor frog

    The moor frog is only found in some parts of the North German lowlands and is now an endangered species. It needs habitats such as protected bogs, which it finds in Lüneburg Heath.

    NABU biotope near Molbath

    Moor frogs can also be spotted in the nature reserve built by NABU near Molbath. From the observation deck in the reserve, not only can the frogs be observed, but – with a little luck – also herons, cranes, and birds of prey. From Uelzen, Suhlendorf, and Rosche, sign-posted cycling tours pass the reserve (the " Heidekartoffeltour ", " Über die Dörfer " tour, and " Kranichroute ").
