There were 4 eggs in the clutch and as of today (July 16, 2011) there are none. The first and send hatched July 11-12, the third on July 14, and the fourth on July 16. Since the parents make a point of carrying off all the shell fragments, it is now really difficult to see the nest site.
Here is one of the parents as of July 12, sheltering the two remaining eggs and the first two chicks.
"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.
The first killdeer egg hatched sometime between yesterday evening and this morning (July 12). The parents were nowhere in sight. Killdeer remove the shell fragments after a hatching and this had already occurred. You can see the chick's fuzzy body, one leg, head, one eye and beak in this picture. It won't be long before it is up and running around.
The Panorama Vista Preserve is nearly 1000 acres of private land held in trust for the public by the 501 (2)c The Kern River Corridor Endowment and Holding Co., Bakersfield, California. It is located along both sides of the lower Kern River, immediately north of the Panorama Bluffs. Volunteers are working to restore and revegetate the land so as to encourage and promote the preservation, scientific understanding, educational benefits, and appropriate recreational of this greenbelt area.
