African wild dogs, Lycaon pictus, a highly social and co-operative species, vote by sneezing, according to findings by Reena Walker of the Botswana Predator Conservation Trust and Brown University in Providence and colleagues. The team reports that when the dogs meet in social rallies before collective motions, the probability of the success of a rally is determined by the number of sneezes in the rally. The quorum was reduced if dominant individuals initiated the rally, but such dominant individuals could also be “overruled” by a consensus of enough subordinates.
