Justification of Red List category
The large population of Stilt Sandpiper is declining at a rate between 20-29% over three generations and the species is assessed as Near Threatened. This reduction is estimated from migration count data, believed to represent a significant proportion of the global population and reflect a genuine ongoing decline in the number of mature individuals.
The main drivers of the decline are uncertain, though the impact of habitat alteration caused by climate change on tundra breeding species are likely to impact this species along with loss of non-breeding habitat in South America. Changes to conditions at stopover sites may also be important. Actions to protect and restore wet habitat in the non-breeding range and retain and expand undisturbed areas at key stopover locations would likely mitigate some of the recorded reduction, but more direct research into this and other shorebirds' responses to threats across the full seasonal range is required.
