The little cub landed some yards away, tumbling heels over head. He showed no surprise, in fact pretended that this was a part of his plan. The instant he rolled on his feet he sniffed the earth eagerly as though he had made a remarkable discovery and started to dig. Without uncovering a thing he presently raced away to overtake mother and the other cub.
Cubs appear to depend upon mother's milk until they are about six months of age. Before this time they may eat a little solid food now and then, but this is done more out of curiosity and in imitation of mother than from desire. It is likely to be July before they do even this and late August before they eat solid things with any regularity. They are not likely to be weaned until just before denning-up time. The Indians in Alaska told me that sometimes the cubs are not weaned until the second autumn of their lives. This certainly is sometimes true, but I think it peculiar to Alaska.
Comical and cunning the cubs appear as they mimic the mother. When she stands up with fore paws against her breast, looking intently into the distance, the cubs stand up with their paws upon their breasts and look in the same direction. When mother turns or sniffs, these cunning little imitators also turn and sniff. The cubs walk up to a spot where the mother has been sniffing and digging and there sniff and dig. If mother continues digging rather long, they find a place of their own and dig. If mother reaches up and pulls down a fruit-laden limb and takes a bite, they too must pull down a twig of some kind and at least look at it.
Around the shores of Chickadee Pond a mother grizzly and her two cubs spent a July day digging out grass roots, willow roots, and probably also grubs. I watched them for hours. Occasionally one took a mouthful of grass or a bite of blue mertensia. After a while mother waded into the pond; cubs of course followed.
The large yellow pond-lilies were in bloom, and mother went about biting off stalk after stalk, apparently forgetting the cubs. One of them grabbed a lily stem and bit two or three times without cutting it. Finally, leaning back, he pulled it apart. He chewed it a little but didn't seem to enjoy it. Then, holding the lily in one paw, he thrust the great golden bulb into his mouth and ate it with apparent satisfaction. The other little cub after much tugging finally uprooted a lily. He chewed at the four-foot stalk in three or four places. Then, taking the bulb in both fore paws, he ate it as though it were an apple.
