Killdeer now nest almost exclusively on the flat, gravel covered, man-made, roofs of shopping malls, schools and businesses. Before civilization encroached on them, Killdeer were shorebirds in the Plover family, that nested on the flat, gravel, natural, beaches, bars, and shores, of rivers and streams across the U.S. and Canada. Killdeer are no longer shorebirds, but are evolving into a species that lives in close harmony with man and man's artifacts. These flat rooftops are actually MUCH SAFER AND BETTER than the original natural sites the Killdeer originally used, and because of these artificial nesting areas, the Killdeer population in the New World is EXPLODING at an astronomical rate.
