60.000 Starlings in Flight.mpg 

Dance with me....60.000 Starlings in flight with two falcons hunting them.
Filmed by Tuur Hofman in March 2011 near Utrecht Netherlands.
He left just the RAW data on you tube. To pity to leave it like that.
I resampled this file did some color and contrast correction adding
music to this marvelous example of emergent behavior in nature.
