Sparrow
Sparrows can be seen on every continent on earth. A long time ago, they lived only in Europe, Asia and Africa. However, people traveled to Australia, North America and South America, and now sparrows are seen there too. The house sparrow is seen in every continent. In Australia, there are no sparrows in Western Australia, as they have not been able to travel across the deserts that separate that state from the eastern states. The government employs people to hunt and destroy any sparrows that might arrive.
