What’s causing Alaska’s sea bird die-off?

Common Murres, like the one held by Wildlife Biologist Leslie Slater on the beach along the Spit in Homer, are turning up along beaches all around the Kachemak Bay area.
Sea birds are having a tough time in Alaska. Thousands of dead murres have been washing up on beaches in coastal communities and even found inland. biologists are working to pinpoint what’s causing this massive die off. Is it El Nino? The warm water blob? Or something else entirely?
