Thousands of snow geese die in Montana after landing on contaminated water

Several thousand snow geese have died after a snowstorm forced large flocks to take refuge in the acidic, metal-laden waters of an old open pit mine in Montana.

Mark Thompson, environmental affairs manager for mine company Montana Resources, said witnesses described the pit as like “700 acres of white birds” on 28 November.

Since 28 November, employees of MR and Arco had used spotlights, noise makers and other efforts to scare or “haze” the birds off the water and prevent others from landing.

The companies estimated that more than 90% of the birds had been chased off by 29 November, Thompson said.
