BUTTE, Mont. — Montana Resources and Atlantic Richfield Company’s growing arsenal of migratory bird tools were recently put to use to scare about 1,100 birds off of the Berkeley Pit.

The Montana Standard reports (http://bit.ly/2fuzrEP ) that the migratory birds landed on Friday and were scared off by a battery powered drone, fireworks, cannons and lasers.

The company scared off the birds in an effort to prevent another tragedy like the snow geese die-off of 2016.

Company spokesman Mark Thompson says there were no bird mortalities this weekend and by Sunday, all the birds were gone. The company began increasing observation of migratory birds in mid-August.
