CONCORD, N.C.,None — Two federally protected birds have nested at the Charlotte Motor Speedway's Tom Johnson camping resort.
SLIDESHOW: Federally Protected Birds Nest At Campground
A camper contacted the camping office after spotting what appeared to be two killdeer birds.
Speedway officials said they took pictures of the birds and sent them to a wildlife biologist in the USDA Wildlife office in Raleigh for identification.
The biologist said the birds were in fact killdeers, which are federally protected by the Migratory Bird Treaty Act of 1918. Under federal law, the nest cannot be disturbed.
The birds are nesting with four eggs, which could take up to 40 days to hatch. That means the feathered campers will be around through both race weeks -- Sprint All-Star Race and Coca-Cola 600.
Speedway officials put up temporary fencing around the area and plan to relocate campers to other areas when they arrive this weekend.
