Broad-billed Sandpiper
Limicola falcinellus

These small waders (16-18 cm) are a moderately common visitor to Australia, occurring in small numbers around Australia's coastlines and occasionally inland. They look superficially similar to the much more common Sharp-tailed Sandpiper, but can be told by the bill, which is thicker at the base as well as longer and slightly downcurved, and the double eyestripe. They breed in Arctic taiga in the northern summer and migrate in a borad swathe from eastern Africa through to Australia outside of the breeding season.
