The eggs measure 9–11.6 cm (3.5–4.6 in) in length and 5.9–7.4 cm (2.3–2.9 in) in width.
The winter habitat of both subspecies is grassland and marshland, often near the coast; they like to visit fields after harvest to feed on discarded grains and while on migration may stop over on mountain lakes.
They have few natural predators, although sometimes Arctic foxes, parasitic jaegers, and glaucous gulls will prey upon their eggs and chicks.
