When I first saw this bird and was trying to get its picture, I thought it might be a Roadrunner because of the way it would run very fast on the road and in open spaces in the field. But I found that it is called a Killdeer.

According to Wikipedia, “The killdeer is a large plover found in the Americas. It gets its name from its shrill, two-syllable call, which is often heard. It was described and given its current scientific name in 1758 by Carl Linnaeus in the 10th edition of his Systema Naturae. Three subspecies are described.” Wikipedia
