Have you ever wondered how many penguins there are in the world? Many scientists wonder about this as well! That is why they have designed drones which fly into the sky and count penguins. Before drones, people would count penguins by using binoculars and long cameras on the ground. While this method worked, it was not always that accurate. By having drones in the sky, scientists have numbers that are 46% to 96% more accurate!
