Cameras placed in hard-to-reach places have shot everything from small desert cats to larger snow cats in the northern Rocky Mountains. Scientists have been able to do
2、cument the private moments of wildlife with leading technology. Grant Harris is a government biologist at the United States Fish and Wildlife Service in Albuquerque, New Mexico. In his words, Theres no doubt that these wild cameras are important tools to learn new information on wildlife. Harris sai
3、d some images help scientists see the influences of climate(气候) change. Researchers with the Wyoming Migration Initiative, or WMI, are using wild cameras along with Global Positioning System, or GPS. But WMI director Matthew Kauffman says as those devices are limited, so is the amount of information
4、 they can gather. However, cameras can be left in very wild areas for days, weeks or even months. They can provide information on how many animals are moving over a given period of time. Putting those cameras in place requires careful planning. Wild videos can show details about animal behaviour. Ho
5、wever, wild cameras have their problems too. Animals such as wolverines and bears sometimes attack them. Scientists do not know if the attacks are the result of anger or interest.
