Australian Pied Oystercatcher
They are a large wader with black head, breast and upper parts with distinct white underparts. The legs, bill and eye ring are bright red.
They form flocks in autumn and winter and love sandy beaches, sandbars and mudflats.
They are a common bird to see but usually take to flight if you approach them directly.
The sexes are a like but the female has a longer bill than the male. From this photo that looks like the female on the left.
They feed on mollusc and crustaceans using their bill for prising, stabbing and hammering.
Between the legs and bill of this bird you can see the discarded shell of what it has in its beak and is about to eat. This bird removed the muscle from the shell in one motion as it withdrew it from the sand.
Immature birds have a dark tipped bill and brownish plumage as shown with the bird above. The eye area is also browner.
