Pied Oystercatcher
Haematopus longirostris

Pied Oystercatchers are closely related to several other species of oystercatcher around the world (including Eurasian, South Island Pied, Variable and Sooty Oystercatchers), which all share the same massive bill, used for cracking open molluscs. They are 48-51 cm in length and are easily told apart from the Sooty Oystercatcher, which has all black plumage. As with other oystercatchers, they frequent coastlines, being happy in rocky areas as well as sandy beaches.
