Physical description Click here for a physical description Sharp-tailed Sandpipers are small waders. Their plumage is highly cryptic. During the breeding season they have a rufous chest, creamy upper belly and white lower belly, flanks, vent and undertail coverts. The chest and flanks are patterned with dark-brown chevrons. The throat is white and lightly streaked dark-brown. They have a brown eye stripe, whitish eyebrows and a rich chestnut crown with dark-brown streaking. The back is dark-brown, with lighter brown edge lining on all feathers. During the non-breeding season the colours are duller in general. The front is striated where it was chevron-patterned during the breeding season and the back is almost all grey, rather than brown. In-flight they have an indistinct wing bar. The eyes have dark irises. The dark-grey bill is straight and about as long as the size of the head. The legs and feet are greyish-yellow. In flight the feet protrude slightly beyond the tail. Juveniles have a prominent rufous chest band and flanks, which are lightly striated brown. The striation does not reach as far down the sides as in adults. Twitcher's tip Compared with Pectoral Sandpipers, they have a chestnut crown with darker brown streaks, not white with dark-grey streaking. Sharp-tailed Sandpipers have a straight bill, while Pectoral Sandpipers have a slightly downcurved bill. Compared with Wood Sandpipers, Sharp-tailed Sandpipers are scalloped and/or streaked, but not spotted. Various species of stints, which can also have brownish chests, are visibly smaller. The correct identification of waders ("shorebirds"), e.g. of the Calidris, Tringa, Actitis and related families or of the Charadrius, Pluvialis and related genera in the field can be quite tricky. We have therefore made an attempt to give some advice HERE.

Taxonomy, classification See Sharp-tailed Sandpiper at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Sharp-tailed Sandpiper is available HERE . Sharp-tailed Sandpipers are strongly migratory. They breed preferably in water-logged tundra in north-eastern Asia and spend the northern winters in South-east Asia or Australasia. In Australia Sharp-tailed Sandpipers are non-breeding migrants from the North that populate mostly the south-eastern quarter of the Australian continent (NSW, VIC and eastern SA) and the south-western corner of WA. They can occasionally be found anywhere in between, including - after significant rainfall - all across the interior of the continent. Sharp-tailed Sandpipers can be found in various types of wetlands, in both freshwater and saltwater environments, including ephemeral wetlands and ephemeral lakes.

Sightings Click here for sighting information A flock of Sharp-tailed Sandpipers was first seen by us in ephemeral wetlands 20 km South of Walgett, NSW, in April 2009. There were about 20-30 birds, which stuck together as a flock while feeding. Also when disturbed, they regrouped to stay in close proximity of each other. Since then Sharp-tailed Sandpipers are found by us semi-regularly in various types of wetlands in inland NSW and regularly by C. Hayne within the Gwydir Watercourse Wetlands, West of Moree. Usually, flocks of tens of Sharp-tailed Sandpipers are found, with a maximum of about 100 birds. Sharp-tailed Sandpipers appear in lakes (such as e.g. Narrabri Lake), ephemeral lakes (such as e.g. Goran Lake), ephemeral wetlands (such as e.g. flooded paddocks and fallow fields), irrigation dams and smaller farm dams of inland NSW. 50+ Sharp-tailed Sandpipers were found by C. Hayne in coastal habitats at Lake Chickiba, Ballina, NSW, in December 2012 and 20 on the beach at Skennars Head in December 2012. In October 2013, B. Hensen reports seeing Sharp-tailed Sandpipers at Eastlakes Golf Course, Sydney, NSW. M. Eaton reports finding Sharp-tailed Sandpipers semi-regularly in various (near-)coastal wetlands in south-eastern QLD. R. Plumtree reports spotting Sharp-tailed Sandpipers at Hollands Landing, Lake Victoria, East Gippsland, VIC, in October 2014. R. Plumtree also spotted Sharp-tailed Sandpipers near Eromanga, in outback QLD, in September 2018. About 50 Sharp-tailed Sandpipers were found by us at Dangars Lagoon, near Uralla, NSW, in October 2018. We also found a small mob of Curlew Sandpipers in an ephemeral wetland ca. 30 km S of Mungindi, NSW, in February 2023.

Behaviour

While overwintering in Australia, Sharp-tailed Sandpipers are often observed by us in flocks, with up to about 100 birds at a time.

The photo below shows that Sharp-tailed Sandpipers can sometimes also be found in man-made habitats, in this case lawn on a golf course.

Does oppressive tropical heat make birds aggressive? On the same day, at the same place, both Sharp-tailed Sandpipers and Wood Sandpipers were observed fighting by B. Hensen.
