FEEDING ECOLOGY AND DIET
Breeding birds eat mainly berries but feed chicks on insects. In nonbreeding season eats mainly bivalve mollusks, also gastropods, crustaceans, annelids, and sea cucumbers. Forages mainly by probing; feeds in large flocks.
Monogamous. Lays eggs May–June. Clutch contains four eggs; incubation is 21 days, by both parents; female leaves after chicks hatch; fledges at 20–25 days.
About 270,000 winter in Australia, where apparently declining. Hunting and habitat loss at stopover zones in China may be a major threat.
