A pod of Bigg's killer whales was caught in action in a rarely seen bird hunt just off Seattle's maritime industrial docks. Kersti Muul, who captured the hunt on video, said it was "a once-in-a-lifetime experience … Not only in the whales' proximity, but also witnessing a rarely seen behavior - chasing and catching the grebe."
