Sharp-tailed Sandpiper
Calidris acuminata

These small birds are one of the most common waders in Australia, migrating here from their breeding grounds in the tundra of northern Asia. They are small waders at 17-22 cm and can occur not only in coastal areas, but inland as well. As with other short-billed waders, they rely on their sight to find prey (rather than probing in mud or sand) and mainly consume insects and other small creatures.
