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 Spanish subpopulation has now stabilised, and it is projected that the global rate of decline will be lower in the next ten years (Green and Hughes 1996).
