In the Amazon rain forest of South America, developers have cleared hundreds of thousands of acres. The mountain lion of North America, for instance, has a range of up to 1,000 square kilometers (386 square miles). The bird is only found on a single island, meaning both its extent of occurrence and area of occupancy are very small.The Tahiti reed-warbler is also endangered because of human activity.
