Students from Northern Arizona University hid in the prairie dog villages to record the sounds they made. The scientists sent four volunteers to walk in the village and to wear a different colored shirts each time. The second time they walked out, the prairie dogs used a different call than the time before. This made the team think that the prairie dogs not only knew they were humans, but also sensed whether he or she was fat or thin and the color of their shirt. Incredible!
