Population status

Stilt Sandpiper
(Calidris himantopus)

The species breeds in the Low Arctic, where only site-specific estimates of trend in the breeding population are available. These studies suggest possible decreases in the east of the range and increases in the west. For example, the species declined by >70% at Churchill, Manitoba, between the 1960s and 1990s and increased by 300-400% at Prudhoe Bay, Alaska, between the 1980s and 1990s (Klima and Jehl, Jr. 2012). Surveys at migratory stopover locations provide the only large-scale and long-term survey data on the continental population, the majority of which breed in Canada. Results from these surveys suggest a 42% decrease in the abundance of Stilt Sandpipers range-wide.
