Bubble-net feeding humpback whales. My first day on Prince of Wales Island, in Alaska’s Alexander Archipelago. was filled with wildlife, rafts of sea otters floated and played, seals lounged on the rocks, island hopping grey wolves appeared in camera traps, I explored my first tide pools full of tiny marine creatures, and there were birds, lots of birds. But it was the brilliant white gulls bobbing on the water’s surface that held the greatest surprise. It seems these smart birds know a thing or two about humpback whales and a free lunch. Watch the birds, Michael said. They point the way to bubble-net feeding humpback whales.
