Researchers have designed a computer program that can identify an individual wolf in the wild analyzing the frequency and amplitude of their howls. They were able to accurately identify an individual Eastern grey wolf (Canis lupus lycaon) with 97% accuracy using the program. This program is expected to be highly useful to wolf biologists and conservationists.
This program would certainly make camping more entertaining as well.
