This two-minute video will dazzle you: Murmuration.
It is the movement of a flock of starlings, as if choreographed, in a jaw-dropping spectacle. This happens each autumn in the evening sky of portions of the UK and elsewhere in northern Europe. Stay to the end of the film to see the reaction of one of the two young women in the boat.
The film is by Liberty Smith and Sophia Windsor Clive. Thanks to my friend Judy for sending it along.
