I hurried home to retrieve photo equipment and my wife. 5 minutes after we were back and parked by side of the road. The animals seemed to take it easy and the calves were playing and feeding while the cow remained close to the forest 50 to 100 meters away.
The cow must have tought they were too bold, and also some people came along the path in the woods so she called her calves. They obeyed without hesitation and trotted towards their mother.
Some horses in a paddock at the nearest farm caught their interest and the family walked quietly in that direction.
