Justification of Red List category
This species is listed as Near Threatened because it is estimated to have undergone a moderately rapid decline over the past three generations (22 years). Over-exploitation in the non-breeding range (in particular in Suriname) may be the principal driver of declines, with eastern-breeding populations also potentially declining due to reduced food supply at key staging sites and changes in arctic breeding habitat, but further information on the rate and drivers of declines is needed.
