Quick Answer
Identify bull caribou in the field by looking for larger antlers, with 4-6 points, and a larger body size, while cows typically have smaller antlers with 2-3 points and a smaller body.
Antler Characteristics
When identifying bull caribou, pay attention to the size and shape of their antlers. Mature bulls typically have large, branching antlers with 4-6 points, while cows have smaller, more slender antlers with 2-3 points. The antlers of a mature bull caribou can span up to 6 feet wide and weigh around 50 pounds, making them a distinguishing feature in the field.
Body Size and Shape
Bull caribou tend to have a larger body size than cows, with a more muscular build. They typically weigh between 400-600 pounds, while cows weigh between 200-400 pounds. Look for a bull’s larger hump on its shoulders and a more prominent ribcage. This can help you distinguish a bull from a cow, especially at a distance.
Migration Patterns and Habitat
Understanding the migration patterns and habitat preferences of caribou can also aid in identification. Bulls tend to occupy the upper ridges and valleys of the tundra, while cows often feed in the valleys and lower areas. Knowing the timing of the migration and the specific habitats that caribou frequent in your hunting area can increase your chances of spotting a bull.
