Talk:Winter cluster

How do they generate the heat?
Maintaining a temperature several degrees higher than surroundings must, even for a cluster of that size require a significant amount of heat generation for such a small animal. Do we know of any specific heat generation methods or behaviours? Do the individuals move around the cluster to keep each other warm or to take their turn around the outside of the cluster?
