We passed through a North Arlington construction site on the way to check on the progress of a new Osprey nest, and the workers pointed out this Killdeer guarding her nest, right next to a chainlink fence. 

   The nest was just a few feet from a narrow roadway chock-a-block with construction vehicles and machinery. The noise was non-stop, but the Killdeer did not seem to mind. 

   When a construction worker approached the nest, the Killdeer scurried away, making that high-pitched whir they like to make.

   We looked at the ground where the Killdeer had been, and discovered four well-hidden eggs. when we came back the next day, we couldn't find them though they were no doubt in view.
