Climate crisis may be a factor in tufted puffins die-off, study says

Researchers believe 3,150 to 8,500 birds starved in Bering Sea due to loss of prey species

The death of thousands of tufted puffins in the Bering Sea may have been partly caused by the climate breakdown, according to a study.

Between 3,150 and 8,500 seabirds died over a four-month period from October 2016, with hundreds of severely emaciated carcasses washed up on the beaches of the Pribilofs Islands in the southern Bering Sea, 300 miles (480km) west of the Alaskan mainland.
