"A bird on the job who lays it's eggs in the gravel. Notice the eggs are colored like the gravel. Then when you walk up on it the mama bird runs from the nest and flops around playing like it's wing is broken to draw you away from the eggs." ~superintendent at Chick-fil-A job site in Wichita.
Killdeer birds in harm's way. Some advice - don't lay your eggs in the gravel... especially on a construction site.
