Justification of Red List category
Despite uncertainty about the possible large-scale inter-year movement of birds between wintering sites, mid-winter counts indicate that the population of this species has undergone a very rapid decline, which qualifies it as Endangered. The total population is now known to be considerably higher than the total recorded during these mid-winter counts, leading to some doubt about the accuracy of global trend estimates calculated solely from winter counts. It is retained as Endangered pending better data from more comprehensive winter counts providing clarity on the overall trend.
