설명
Counting animals is a challenging exercise. Many animals only come out at night. Others are very shy, and have become adept at avoiding people. Some live in remote places where it is difficult for people to observe them. Technology helps to make animal surveys easier. Examples include using satellite imaging to count whales and setting traps to count amphibians."
