Killdeer - pretending to be injured as my car drove slowly down the road from a winery in Napa. Its nest was probably right by the edge of the road and they feign injury to distract predators from the eggs or newly hatched chicks. (They are known to nest on the ground in less than safe locations.) After taking several photos, I tried to gently encourage her/him to move out of the road before a car came. It wasn't a busy road, but when a car came, the Killdeer quickly flew off the road.
