Spring Grizzly Bears Roll Rocks

Grizzly rolling rocks

Grizzly bears start to appear on the beaches to turnover rocks in late May. 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 plant food is relatively scarce during spring and bears will continue to loose weight until well into June. Plant foods make up the majority of a bear’s diet (sometimes, as much as 90%) until the salmon arrive in the rivers in late August.
