On Thursday around 11:30 am, a flock of storks approached the nest and circled above it for a while. The pair in the nests reacted with loud bill-clattering, signaling that the nest was occupied. None of the circling storks tried to land. They started flying east.
Storks reach maturity around the age of 3, after this they start reproducing. At that time they go back to the area that they were born in. If they don't find a pair or nesting place, they wander around in smaller groups.
