Pectoral Sandpipers breed throughout the circumpolar Arctic. In Canada, they are found in wetlands of the Low to Mid Arctic. Migration monitoring surveys suggest a moderate decrease in the abundance of Pectoral Sandpipers relative to about 1970. Few data are available from the breeding grounds, so the true status of the Canadian population is uncertain. With more than 80% of the global breeding population, Canada's responsibility for the species is very high. The species is a candidate wildlife species for assessment by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.

Conservation and management

In winter, Pectoral Sandpipers and several other shorebird species rely heavily on moist grassland habitats of South America. These grasslands have long been used for grazing livestock, but economic conditions are increasingly favouring their conversion to croplands which are less suitable for wintering shorebirds (e.g., Isacch and Martínez 2003). Efforts to preserve migratory staging areas and critical stopover sites will be beneficial (Farmer et al. 2013).


Bird conservation region strategies

Environment and Climate Change Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified as priorities for one or more of the following reasons:

  • conservation concerns (i.e., species vulnerable due to population size, distribution, population trend, abundance, or threats)
  • stewardship responsibilities (i.e., species that typify the regional avifauna or have a large proportion of their range or population in the sub-region)
  • management concerns (i.e., species that require ongoing management because of their socio-economic importance as game species, or because of their impacts on other species or habitats)
  • other concerns (i.e., species deemed a priority by regional experts for other reasons than those listed above or because they are listed as species at risk or concern at the provincial level)
