Animal Espionage

How do you study giant armadillos when hardly anyone has ever seen one? Or figure out if a whale is losing weight—without getting too close? Camera and drone technologies are allowing scientists to watch animals more closely than ever before, without disturbing them. Scientists in India are using thousands of camera trap photos to track tigers' movements. In Canada, caribou outfitted with collar cams show conservationists which habitats they rely on throughout the winter. Capturing everything from the unexpected to the comical, these technologies are giving wildlife managers insights that could ultimately help them fight extinction and habitat loss.
