Shorebirds that breed on coastal and upland habitats face severe population declines as their specialised nesting and feeding sites disappear. Habitat loss causes both population and individual-level welfare impacts.
Habitat-deprived shorebirds face nutritional stress when unable to find adequate invertebrate food. Breeding failure — often from nest predation or disturbance in degraded habitats — involves significant parental investment with no reproductive reward. Birds that cannot feed adequately experience physiological stress, reduced body condition, and increased vulnerability to disease and cold. Habitat quality directly affects both survival and individual welfare state.
