Spring grizzly bears grazing on the sedge grass in the Glendale River estuary. This mother and cubs were frequent visitors to the estuary because of the protein rich grass and the good beach for rolling rocks for a different protein. Triplets are reasonably common and on occasion a mother with four cubs will pass through our viewing area. The reason the bear population is increasing is the number of births some of which are multiple births and with the abundance of food means most of the cubs survive. It is an interesting circle because when a pregnant bear hibernates if it is in good health (because of lots of food) the eggs are not absorbed and therefore more bears give birth and so on.
Grizzly Bear Grazing
In the spring grizzly bears come to the Glendale River estuary to feed on the sedge grass as it is up to 25% protein and the berries in the coastal forests are not yet available. At lower tides when more of the beach is exposed the bears will spent more time turning over rocks in the inter-tidal zone looking for food high in protein such as crab, clams, barnacles, amphipods and other tiny invertebrates. Much of a grizzly’s time in the spring is spent in search of food. This changes in the fall once the salmon arrive and food is more abundant. Spring grizzly bear watching is along the shore from the water while the fall viewing is from a stationary platform.
