Economic Importance and Threats
Threats:  Anthropogenic
(The species is vulnerable to extensive land reclamation projects that encroach upon staging areas and is threatened by the over-exploitation of shellfish which leads directly and indirectly to reductions in prey availability. The species also suffers from disturbance in the non-breeding season as a result of tourism, foot-traffic on beaches, recreational activities and over-flying aircraft, which together reduce the size of available foraging areas. It is also potentially threatened by industrial pollution and oil exploration This species hunted illegally. )
Threats:  Natural threats
(Susceptible to avian influenza so may be threatened by future outbreaks of the virus.)
Importance:  Commercial
(For the purpose of utilization this species is hunted illegally.)

Ecology
Habitat:  Estuarine, Rocky, Sandy, Muddy, Coastal
