Shorebird Roost Protection: Welfare at High-Tide Gathering Points

High-tide roosts are critical welfare resources for shorebirds - disturbance at these sites has disproportionate welfare impacts on large numbers of birds.

Key Facts

Shorebirds must roost at high tide when foraging mudflats are covered by water
High-tide roosts concentrate thousands of birds in small areas, making disturbance highly impactful
A single disturbance event at a roost forces birds to fly when they should be resting and conserving energy
Repeated roost disturbance causes measurable reductions in body condition and survival rates
Roost sites require protection with buffer zones where human access is restricted at high tide
Climate change and sea level rise are threatening traditional roost sites with flooding

Welfare Considerations

Shorebird roost welfare illustrates how spatial concentration creates vulnerability - a disturbance that would affect one or a few birds at foraging sites can simultaneously impact thousands of birds at high-tide roosts. The welfare consequence of forced flight during rest periods is energetically significant - energy spent flying is energy not available for thermoregulation and survival. For migratory birds in poor body condition at the end of long flights, forced roost disturbance can be the marginal factor determining survival. Protecting roost sites through buffer zones and access restrictions during critical periods is a high-impact welfare intervention.
