Mergansers, mallards and other ducks reside in the park year-round, along with bald eagles, great blue herons, Brandt's and pelagic cormorants, common loons, and many other waterbirds.
Many transients stop in the park on their way, north and south.
Other wildlife includes bears, cougars and smaller mammals of the non-threatening kind, including bog animals. Gray whales migrate along the beaches, moving north from mid-February on their journey to the Bering Sea and the Arctic Ocean. In late December, the grays are seen heading south to their breeding grounds in the lagoons of Baja California. Whale-watching excursions are available in Tofino and Ucluelet. The optimum time for whale watching is from late February to early June.
