Population status

Upland Sandpiper
(Bartramia longicauda)

Upland Sandpiper populations are best monitored in Canada by the Breeding Bird Survey (BBS), though the population in the Yukon is not well covered. BBS results indicate a 43% decrease in the Canadian population since about 1970. However, the negative trend has abated during the most recent period (2006–2016). At the regional level, population trends vary among the Bird Conservation Regions (BCRs) for which there are reasonably reliable BBS results (displayed below). Upland Sandpiper populations have increased in the west (Prairie Potholes BCR), but have decreased (Lower Great Lakes/St. Lawrence Plain and Atlantic Northern Forest BCRs) or remained relatively unchanged in the east (Boreal Hardwood Transition BCR). BBS data from throughout North America indicate little overall change in the continental population. The Upland Sandpiper is currently below the lowest acceptable level relative to its national population goal (see Canada graph below), though that may change if the recent population increase continues.
