For a BBC program about penguins called Penguins - Spy in the Huddle, a special camera was designed to look like a penguin egg. After placing the egg-cam amidst a penguin colony, it was met by a curious striated caracara who eventually snatched the device and took flight. With the falcon's ascension into the air, the egg-cam managed to capture some stunning aerial shots of the penguin colony below—the first video of its kind to be filmed by a bird.
To the bird's dismay, the "egg" fell out of the caracara's grasp and into the field of vision of a couple of turkey vultures. They, too, were intrigued by the egg-like structure. It was especially enticing because the rest of the eggs in the area were already hatched and these predators were eager to crack into a meal for themselves. After a few pecks with their beak at the cleverly disguised camera, they wound up knocking it down a hill, right back into the penguin colony.
Check out the video, below, to see it all play out.
