Behaviour
Diet
The diet includes marine invertebrates, particularly mussels, limpets and chitons, also crabs and barnacles. It uses its strong bill to dislodge food and pry shells open.
Breeding
The nests are small bowls or depressions close to the shore filled with small pebbles and shell fragments. 2-3 eggs are laid and are incubated for around 26-28 days. The chicks are capable of leaving the nest after one day; they stay in the territory for about 40 days after fledging. The fledged juveniles stay in the territory until the next breeding season. If the parents migrate, that year's chicks will migrate with them; this happens more often in the north of the range.
