Dawn’s Chorus: Mating Calls of Marsh Frogs at Sunrise

Barycz Valley, Poland
Recommended charity: Orion Organizacja Społeczna

Depending on the weather at the turn of March and April, you can witness an amazing spectacle of moor frogs mating in small water reservoirs, along with the awakening of nature.

During this period, the males turn a beautiful blue color due to the accumulation of lymph in the subcutaneous lymphatic sinuses. The azure shade of their skin is temporary and only lasts during mating.

The moor frog mating call is unmistakable, sounding like “wuog … wuog … wuog,” resembling a gurgling and chuckling bottle being opened underwater. During the breeding season, the marsh frogs’ amorous calls are often accompanied by deep grumbling sounds produced by common grass frogs, which inhabit the same areas.
