Wildlife filmmaker Bertie Gregory documented a pod of B1 Antarctic killer whales locating a resting Weddell seal. “With snow falling, flying the drone felt like being in space with stars whizzing by. Having found the seal, the pod then began to spy-hop to size up the target and figure out how to get it into the water,” Gregory says. “The intelligence of these killer whales is spine-tingling.” Watch #AnimalsUpClose with Bertie Gregory, now streaming on Disney Video by Bertie Gregory and Tom Walke
