This photo shows that grizzly bear cubs are often different colours and can be quite different in size even though they are siblings. The size difference is often a result of one being a male and more aggressive than a female. This means first to nurse and the first to solid food once they are on the beach in the spring. It could also be due to the fact that siblings may have different fathers as females will mate with multiple males. A genetically larger male may produce a larger cub. And the difference in colour is a result of the different mating partners. As the season progress and salmon become more of their diet the oils will cause the fur to darken but these are “spring cubs” and salmon are not in the rivers.
The why of this grizzly bear’s style is that her front paw was damaged in a fight with another bear so she is unable to hold the salmon against a rock and balance to eat. She is an excellent fisher and catches all the salmon she can eat and is getting quite fat in preparing for hibernation. As time has progressed she has become very adept and developed her own fishing and eating methods and it is time that will determine if she heals over the winter and we see her back next year.
