BULL SHOALS, Ark. -- As attempts to deter more than a thousand black vultures from congregating at the Bull Shoals Dam and Powerhouse in the Ozark Mountains of north central Arkansas have failed, the Army Corps of Engineers is trying a new scare tactic.
On Tuesday, officials hung vulture "effigies" in an effort to keep vultures from damaging the dam's structures.
"We'll see if we have a lot of success," said Bruce Caldwell, supervisory natural resource biologist with the corps' Mountain Home Project Office.
An estimated 1,500 to 1,600 vultures have taken up residency at the Bull Shoals Dam and Powerhouse. So far, the birds have caused more than $120,000 in damage to both tower roofs, said Steve Hernandez, the Army Corps of Engineers powerhouse supervisor.
Besides tearing apart the tower roofs, which are a rubbery material, the painted surfaces of the towers are starting to show the effects of the vultures' caustic droppings, he said.
