The upland sandpiper (Bartramia longicauda) is a large sandpiper, closely related to the curlews. Older names are the upland plover and Bartram's sandpiper. In Louisiana, it is also colloquially known as the papabotte. It is the sole extant member of the genus Bartramia. The genus name and the old common name Bartram's sandpiper commemorate the American naturalist William Bartram. The species name longicauda is from Latin longus, "long" and caudus, "tail". The name "Bartram's sandpiper" was made popular by Alexander Wilson, who was taught ornithology and natural history illustration by Bartram.
An adult is roughly 30 cm (12 in) long with a 66 cm (26 in) wingspan. The average weight is 170 g (6 oz). This odd bird has a small dove-like head on a long neck. It is heavily marbled black and brown on the back and wings. The neck is streaked with dark brown which continues down to the breast and on to the flanks. The belly and undertail coverts are white, and the tail is quite long for a sandpiper. The upland sandpiper also has a white eye-ring and long yellow legs.

GBIF citizen-science records
It is estimated from how often the Upland Sandpiper is recorded against all the birds logged in Amacayacu National Natural Park (10 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
