ABR received a large quantity of fresh grapes from a supporter. Curator Coy “served” them to the cubs by throwing the grapes over the fence for them to find. Bears do love grapes, and it didn’t take the cubs long to locate the yummy treats and chow down. They even did so in view of the camera, so we can see their enthusiasm.
Although by far the most of a bear’s diet is plant-based, about 15% is meat, mostly in the form of insects or other small critters. Coy saw two such creatures that could have been (but weren’t) food for the cubs. If the cubs had not been so busy with the grapes, they might have eaten one of these.
The cubs do, indeed, supplement the diet that the curators provide by catching and eating the various critters that inhabit the Wild Enclosure. We’ve seen a lizard tail hanging out of a cub’s mouth, and have watched cubs lick insects off of the bark of a tree. As omnivores, bears will eat most anything that they find.
