Despite the false rumors, wolves are not color blind. Though not as astute as human color detection, they can detect a few colors such as blue and red. A Social Animal Wolves live in packs of 4-6 individuals on average. The number in a pack will depend on how much territory is available, and the amount of prey species. Moose hunting packs may have larger packs, since a single moose can support more wolves.
Wolves depend on each other for survival, taking advantage of cooperatively hunting.
It has been suggested that wolves communicate a plan of strategy for hunting. However, it is more likely that wolves simply remember successful hunts previously, and also make adjustments to their tactics from assessing the others whereabouts. Think of it like playing basketball. You have the ball, and look for openings to pass or weakness in the defense that could make for a basket. Their main diet consists of ungulates, such as deer, moose and caribou.
