Population justification: The global population has been estimated at 310,000-380,000 individuals (Wetlands International 2015). The European population is estimated at 35,900-57,300 pairs, which equates to 71,700-115,000 mature individuals or 107,550-172,500 individuals (BirdLife International 2015). An updated global population estimate using this new information from Europe provides an estimate of 280,000-345,000 individuals. This roughly equates to 180,000-230,000 mature individuals.
Trend justification: The overall population trend is not known. Some populations may be stable or increasing (Wetlands International 2015), whilst the European population is estimated to be decreasing by less than 25% in three generations (BirdLife International 2015).
