Common Greenshank
Tringa nebularia

Common Greenshanks are fairly large waders (30-35 cm) and are found across much of the Palearctic (i.e. Europe and Asia) and Australasia. The Far Eastern population overwinters in Australia and makes its way up the East Asian–Australasian Flyway to breed in the northern summer. This particular bird is in summer plumage, which is greyer and includes the spotting on the neck and breast, while winter plumage can be seen here on the Australian birds page. Their diet consists of molluscs, worms and crustaceans found on shorelines, estuaries and inland pools.
