Here's why Montana officials are scaring birds on purpose
Tuesday, November 13, 2018, 3:21 PM - A new high-tech drone has been deployed to menace and scare birds in an effort to save their lives.
The Berkley Pit in Butte, Montana is an old copper mine and the water is toxic to birds.
Two years ago 10,000 geese were killed at the site when they landed there.
To prevent a re-occurrence workers have modified a large drone with strobe lights and ear-piercing sounds to deter birds.
"The intent is to get up close enough that they can hear it, show the size, let them hear the sound and start to get them agitated, then maneuver to try to get them to lift up off the water," Jim Jonas of the Atlantic Richfield Co. told CNN.
Workers are also using a remote-controlled boat that can quickly get to birds that have already landed in the water.
