How human activity during the breeding season affects shorebirds and what beach visitors and land managers can do to protect nesting birds.
Shorebird nesting welfare is particularly sensitive to human presence because nesting birds must choose between fleeing to protect themselves and remaining to protect eggs or chicks. The cost of repeated disturbance accumulates: energy depleted in repeated flushing, chicks that cool dangerously when parents are away, and eggs lost to opportunistic predators that follow in the wake of human disturbance. The animals experience genuine physiological and welfare costs from each disturbance event. Respecting nesting areas during the breeding season — which typically runs from April to August in the northern hemisphere — makes a direct and measurable difference to breeding success and individual bird welfare.
