Bergmann’s Rule refers to animals being larger in the north, even non-human animals seem to comply with this theory. It has often been said that mountain lions in Canada are larger and can exhibit less tolerant or elusive behavior. However this story is quite astounding, even for Canada. The lion sounds to be within widely recognized weight limits so it wasn’t bigger than normal but its behavior was bafflingly aggressive. The story was obviously terrifying for the men involved, who reacted appropriately by fighting back and then securing themselves in their truck. This has to be one of the most unusual attacks we have ever heard of. Cougar attacks are exceptionally rare and we hope the investigating agency is able to identify the reasons for this almost unique event. We will let you know if any more information emerges.
