Anybody home? There are wild animals living in our cities, neighborhoods, and farmlands, but they often go unnoticed. Many wildlife species are shy around humans, making them hard for scientists to detect without special tools. Enter the camera trap, a motion- or heat-sensored tool that allows wildlife biologists to study animals remotely, without catching or disturbing them. Scientists from Colorado to Cambodia use these tools to learn more about how humans and wildlife share our world. Learn more about how scientists use camera trapping data through the links to lessons and researcher bios below, and also check out the eMammal website, a camera trapping data repository with lots of great resources for teachers and students!
