Can`t help it, gotta share this one also :)
The annual murmuration at Kinderdijk. Every year the European Starlings gather in several hotspots throughout Europe where they prepare for the journey south. Every night just before sunset little groups fly back to the spot and form large flocks with over 10.000 individuals (last week the count was more than 50k). Just before the sun sets they "dance" in 1 huge flock,much like a schooling sardines before going to sleep.
