The U.S. Army Corp of Engineers are battling flocks of vultures at Bull Shoals Dam.
This past month there have been between 1,200-1,500 vultures that are causing damage.
The droppings are very corrosive, and so their droppings are corroding the metal and the painted surfaces as well as the streaks it causes down the dam, according to the U.S Army Corps of Engineers.
The vultures' droppings have pretty much painted the bridge rails white. Now, the Corps is considering using bird spikes, metal spikes on top of the rail, to keep the birds from perching there.
The Corps believes the vultures must enjoying the high perch, warm air drafting up from the concrete dam, and plenty of dead fish to eat. He figures a cold stretch will send them further south.
