The Black Sun Phenomenon : Denmark
During spring in Denmark, at approximately half an hour before sunset, flocks of more than a million European starlings (sturnus vulgaris) gather from all corners to join in the incredible formations shown below. This phenomenon is called Black Sun (Sort Sol), and can be witnessed in spring (March-April) or autumn (in September) throughout the marshlands of western Denmark – Tønder, Højer. The starlings migrate from the south or Norway and spend the day in the meadows gathering food, sleeping in the reeds during the night.
