This January 2015 video is about Bewick’s swans, waking up early in the morning in De Wilck nature reserve in the Netherlands. They start to whistle softly and shake their heads. Signs that they are about to fly away to the fields to feed.
Recently, Bewick’s swans have come again to De Wilck. If the winter weather will not become harsher, then they will stay there. As long as the swans are there, De Wilck is closed to the public, in order not to disturb the birds.
