If there's something that I hate more than one of those freaking winged sons-of-dinosaurs known as birds, it''s a few thousand of them invading the entire sky, networked like a single individual. It's a natural phenomenon called murmuration.
This video of a massive murmuration made of thousands of starlings was captured by Sophie Windsor Clive in River Shannon, Ireland. It's a beautiful video. That creeps the bejeezuss out of me.
