What does a flock of more than a million starlings look like?

Earth Science Picture of the Day has some wonderful images of flocks of European starlings (sturnus vulgaris) which appear in Denmark during spring.

I remember BBC’s Springwatch with Bill Oddie had some amazing footage of starlings in last years series.

It is breathtaking to see the way they move. If there is a location near you where starlings appear and you have an opportunity to go out and see them, please do!
