"Hide in plain sight" seems to be the rule when killdeer choose a nest site. Not for them are hidden places under bushes or rocks or up in tree branches or cavities. They prefer open spaces such as this nearly barren stretch of ground near the plant nursery, not far from the road. The red arrow points to the nest which even at a short distance is easy to pass by.
But, if the parent is there, it will do its level best to lead you away by going into its "broken wing" routine: tottering (but perhaps complaining in a loud voice), dragging a wing, flopping and toppling over but somehow still leading its unwelcome visitor away.
