A murmuration of sheep
Sheep herding, New Zealand style. It takes some well-trained dogs to pull this off, and you have to look closely to even see them in this video from aerial photographer Tim Whittaker. It was posted to YouTube in February 2016 and has almost two million views. It’s easy to see why. The movement is as mesmerizing as a starling murmuration. Of course, the sheep are being directed, while the birds manage it all by themselves — and without knocking each other out of the sky.
