Justification of Red List category
This charismatic species is listed as Critically Endangered because it has an extremely small population that is undergoing an extremely rapid population reduction. This is because of a number of factors, including habitat loss in its breeding, passage and wintering grounds, that are compounded by disturbance, hunting and the effects of climate change. Fledging success and juvenile recruitment are very low, leading to fears that the population is ageing rapidly; action is now urgently required to prevent the extinction of this species.
