If you were to look up in the sky and see this huge black mass contorting into different shapes, you might get a little creeped out. Although it looks alien, it’s actually just a European Starling Murmuration. The birds will group together in their thousands and perform various stunts before roosting for the night. Scientists believe that they do this to intimidate predators such as falcons. And if you think the gif looks cool, watch this.
