Ground-nesting shorebirds are highly vulnerable to disturbance at nest sites, with human presence causing nest abandonment, egg chilling, and reduced reproductive success.
Shorebird nest disturbance welfare involves both reproductive welfare, the ability to successfully raise young, and acute welfare, the distress of a bird flushed from its nest repeatedly during a vulnerable period. Ground-nesting birds did not evolve with the level of human and dog disturbance characteristic of popular beach areas. Volunteer wardening programs that educate visitors and physically protect nesting areas have proven highly effective at reducing disturbance without restricting beach access entirely. The welfare return from relatively modest wardening investment is substantial in species with already-declining populations.
