Alarm as hundreds of dead horned puffins are washing up along the coast of Alaska adding to the list of murres, whales, sea lions and starfish

The last couple of years it was murres and whales that had been turning up dead in large numbers on Alaska beaches or in Alaska waters.
Now it is puffins, bright-beaked birds that are icons of Alaska's marine communities.
Since mid-October, residents of St. Paul Island in the Pribilofs have found over 200 dead tufted puffins washed ashore on the Bering Sea beach, along with additional dead horned puffins and murres.
The extent of the die-off - 217 dead tufted puffins found as of Nov. 4 - is alarming and appears to be linked to unusual warmth in the region, said University of Washington ecologist Julia Parrish, who has been consulting with St. Paul islanders.

The toll dwarfs past counts of dead tufted puffins found on the beach, she said.
 "In 10 years of standard beach surveys, we've only found, at most, three tufted puffins.
There's a very big difference there," said Parrish, who is executive director of the Coastal Observation and Seabird Survey Team program - COASST- based at the University of Washington.
Put in context, the numbers are particularly worrisome, she said.
What is washing ashore is likely only a small fraction of the total number of puffins dying in the area, at most 10 percent but more likely a much smaller percentage, she said.
The Pribilof-breeding population of tufted puffins totals only about 6,000, so a death toll in the thousands represents a large portion of that, she said.
Also significant is the presence of puffins as far north as St. Paul so late in year, highly unusual because the birds usually disperse to the south in the season, she said.
The puffins' carcasses are mostly intact - showing no evidence of predation - but they are emaciated, indicating severe food shortages in their habitat, Parrish said.
Necropsies of puffins sent from St. Paul to the U.S. Geological Survey's National Wildlife Health Center revealed the birds died of starvation, she said.
Unusual warmth has been documented this fall on and around St. Paul Island.
Sea-surface temperatures in the Bering Sea have soared well above average since August, according to the National Oceanic and Atmospheric Administration.
Air temperatures have also been much higher than normal.
Twenty of the days in October had record-breaking or record-tying high temperatures in St. Paul, and the month's average temperature there was 6.2 degrees higher than the long-term normal, according to the National Weather Service. September's average temperature in St. Paul was 4.6 degrees higher than the long-term normal for the month, and August's average temperature was 4.1 degrees higher than normal for that month, according to the Alaska Climate Research Center at the University of Alaska Fairbanks.
While experts say that any particular event can't be tied to climate change because of the normal variability of weather, overall global warming, blamed in part on humans' use of fossil fuels, is linked to a rise in sea-surface temperatures.
President Barack Obama has made addressing climate change a central focus of his administration, but President-elect Donald Trump has dismissed global warming as a Chinese conspiracy and has put a climate change doubter, Myron Ebell, in charge of his Environmental Protection Agency transition. Pamela Lestenkof, co-director of the St. Paul tribal government's Ecosystem Conservation Office, said strong southerly winds blew in for most of the fall, a big departure from the usual seasonal weather on the island.
"We've had a lot of wind and high surf," she said.
Only recently have winds shifted to the north, she said.
The local St. Paul tribal group conducts regular beach surveys in coordination with the COASST program.
Lestenkof has been participating in the beach surveys herself and went out as soon as she could after learning about the first discoveries.
"I saw just over 40 dead puffins, and that was pretty alarming," she said.
She said the search for dead puffins started in earnest after two dead juveniles were collected earlier in October.
Even puffins that are not dead appear to be in trouble, Lestenkof said.
