Goats Don’t Vote: Article in New York Times

The New York Times published an article on our recent paper which developed a method for teasing apart different hypotheses for the behavioral mechanisms underlying group collective movement decisions. We tested this model on data I collected on free-ranging goats using dataloggers that contained gps, accelerometers / magnetometers and audio recorders. We did not find support for the hypothesis that goats “vote” with their body position. Rather, data support the hypothesis that they use a self-organized method of following other group members as they begin to move off. Our model will help to disentangle the behavioral methods involved in collective movement decisions in a variety of species.
