Snowy plovers nest on open beaches and are highly vulnerable to human disturbance during breeding season, leading to nest abandonment and chick mortality.
Plover chicks that lose parental protection face immediate threats from exposure, predation, and starvation. Even brief disturbances during incubation can break the thermal bond between egg and parent, reducing hatch rates. Adults repeatedly flushed from nests experience elevated stress hormones and energy depletion.
