[edit] Description
The name "oystercatcher" is something of a misnomer because these birds rarely eat oysters, which are found mainly on rocky coastlines, however in areas where oyster cultivation is present, Oystercatchers are frequently seen walking on infrastructure, 'catching ' the odd oyster. Pied Oystercatchers frequent sandy coastines, where they feed mainly on bivalve molluscs, which are prised apart with their specially adapted bill.
This Australian variety is easily recognized by the characteristic 5–8 cm long orange-red beak, slender pink legs and black and white plumage. With the wings extended, a white wing-stripe is also visible. The male and female show little differentiation, except that the males generally sport a shorter, wider beak.
[edit] 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.
[edit] Conservation Status
The Pied Oystercatcher is considered Federally to be 'secure' and in NSW, Australia is listed as 'vulnerable'.
