In the spring grizzly bears are on the beaches to turnover rocks. This inter-tidal zone “food” is high in protein and is made up of crab, clams, barnacles, amphipods and other tiny invertebrates. The “beach food” is important because the numerous berries (huckle berries, salmon berries, black berries, thimble berries, salal berries etc.) do not become ripe until late spring and summer. This is a common pose for the grizzlies as they roll rocks, as rock roll easier down hill and were are in a boat on the down hill side of the bears. Also the bears accept our presence and any concern (fear) they have comes from up the beach where larger bears may approach out of the bush or forest.
Grizzly bear cubs are born in the den in January or Febuary. The cubs will weigh approximately 500 grams ( 1 ½ pound) at birth, and arrive into the world blind, hairless, and toothless. The cubs will grow to weigh 3-4 kg (7-9 lbs.) prior to emerging from the den in spring. This photo was taken in early September so these first year cubs are six or seven months old. As you can see from the photo that this mother grizzly is still nursing. The milk from a grizzly is rich in fat, approximately 30% compared to a cow at 3% so these cubs will weight 27 – 45 kg. (60 to 100 pounds). Also the photo shows the difference in size in the three cubs the one being much larger. This is common and shows which of these cubs has a better chance of survival.
