15 world's most bizarre natural phenomena

Black Sun

Known as the black sun phenomenon, flocks of more than a million common starlings called murmurings, can be seen in areas of the UK, in Ireland, and in Denmark.What makes this phenomenon even more amazing is the fact that these birds are able to fly in unison. This is due to the fact that each starling in a flock is connected to every other. When a flock turns in unison, it’s a phase transition.
