Habits
Pied Oystercatchers feed mainly on bivalve molluscs, but also take other invertebrates. The techniques they use to break open the shells of the molluscs vary greatly and are thought to be learned behavior.
They nest in shallow scrapes made in open areas near the shore and produce 2–3 eggs in a typical clutch. Each couple protects its nesting area and often uses the same area year after year. Like the gulls they share the shore with, Oystercatchers will band together to mob a perceived threat.

Famous quotes containing the word habits:
“The important thing about travel in foreign lands is that it breaks the speech habits and makes you blab less, and breaks the habitual space-feeling because of different village plans and different landscapes. It is less important that there are different mores, for you counteract these with your own reaction- formations.”
—Paul Goodman (1911–1972)
“Good habits formed at youth make all the difference.”
—Aristotle (384–322 B.C.)
“The Americans ... are almost ignorant of the art of music, one of the most elevating, innocent and refining of human tastes, whose influence on the habits and morals of a people is of the most beneficial tendency.”
