One of the best ways to learn is to watch another and this is true of grizzly bears as it is of humans. This mother grizzly in the Glendale River estuary of Knight Inlet is teaching by example. At low tide especially in the spring when the salmon have not arrived in the river to spawn will bring the grizzly to the beach. The turning over rock produces food high in protein, which is made up of crab, clams, barnacles, amphipods and other tiny invertebrates. This cub is ready to share moms food and will soon be turning it’s own rock in search of a meal.
Wikipedia offers a good explanation of spyhopping: “When spyhopping, the whale rises and holds position partially out of the water, often exposing its entire rostrum and head, and is visually akin to a human treading water. Spyhopping is controlled and slow, and can last for minutes at a time if the whale is sufficiently inquisitive about whatever (or whomever) it is viewing.
Generally, the whale does not appear to swim to maintain its “elevated” position while spyhopping, instead relying on exceptional buoyancy control and positioning with pectoral fins. Typically the whale’s eyes will be slightly above or below the surface of the water, enabling it to see whatever is nearby on the surface.
Spyhopping often occurs during a “mugging” situation, where the focus of a whale’s attention is on a boat rather than on other nearby whales. Spyhopping among orcas may be to view prey species. For this a spyhop may be more useful than a breach, because the view is held steady for a longer period of time.”
