Sea lions back in B.C.'s Howe Sound and occupying private docks.

Sea lions have returned to Howe Sound and are using two private docks in West Vancouver, producing loud barking and bellowing; experts say both Steller and California sea lions are present and their arrival reflects a recovering marine ecosystem.

Sea lions have returned to Howe Sound and are using two private docks in West Vancouver. Their loud barking and bellowing have prompted some complaints to local officials. Scientists report both Steller and California sea lions are present. Researchers link the visits to larger prey numbers in the area and say the animals' return reflects a recovering marine environment. Key facts: - Sea lions have taken over two private docks in West Vancouver and are creating notable vocal activity along the shore. - West Vancouver Mayor Mark Sager said residents have complained about the noise and remarked on the animals' presence. - Two species are reported: Steller sea lions (native, among the largest sea lions and noted as a species of special concern in Canada) and California sea lions (the louder species and common in B.C. waters in winter). - Researchers at the University of British Columbia noted increased anchovy numbers have attracted sea lions, seals and humpback whales to Howe Sound. - A dock near Garrow Bay Park used by sea lions last year has been blocked off with a wooden fence to prevent animals from using that site. Summary: Researchers describe the sea lions' return as part of a larger ecological recovery in Howe Sound compared with past decades. Seasonal patterns differ by species, with California sea lions often present from November to March and Steller sea lions traveling to breeding areas; the timing and longer-term presence will unfold over the coming months.
