Calling Common Frogs and Moor Frogs at a water pool in spring

It is early spring and the first warm days of the season arrived. At noontime the temperatures reach almost 20°C for the first time of the year. Wind blows through the trees. The birds already slowed down their daily singing activity, but in a small and shallow and sunlit water pool amphibians become active. It takes a couple of minutes until the first Moor and Common Frogs start calling. Splashing sound comes from fighting and spawning. Other clicking sounds might come from water insects.
