During the winter the terns have spent time on the sea near West Africa. 5,000 km they have now returned to the breeding place. “Relieved”, they realized that the rafts were still there and even a third raft had been laid out.
In the next few days the birds visited the river Rhine and the gravel pits. They now know the best places for fishing,
The Common Terns usually breed together with their old partner. Both are played together. Thus, the older, more experienced animals have already started laying eggs.
We took a photo of a raft. How many clutches can be seen?
