Population justification: The population is estimated to number 2,500 individuals in Spain and Morocco (J. A. Torres Esquivias and A. Green in litt. 2002); 400-600 individuals in Algeria and Tunisia (H. Azafzaf and P. Isenmann in litt. 2002); 5,000-10,000 individuals in the east Mediterranean and south-west Asia, and 10 individuals in south Asia (Wetlands International 2016). This totals 7,900-13,100 individuals, roughly equating to 5,300-8,700 mature individuals. Within Europe the breeding population is estimated at 250-610 pairs, which equates to 500-1,200 mature individuals. The number of wintering birds in Europe is estimated at 7,500-15,900 individuals (BirdLife International 2015). However, a count of over 20,000 individuals were counted on the Tengiz-Korgalzhyn Lakes, Akmola region, Kazakhstan in September 2016 (ACBK 2016).

Trend justification: Attempting a global trend analysis using current figures, as presented by Orueta (2016), gives a decline of 34.4% between 2005 and 2013, which would equate to a decline of 61.3% over 3 generations (18 years). However, given that the global total number of individuals in the 2013 mid-winter count was only 4,635 individuals this suggests that a lot of individuals were missed during these surveys (as Azerbaijan alone was estimated to have 5,000-10,000 individuals over-wintering in 2014 [BirdLife International 2015]). Support for the idea that many individuals are missed during these counts comes from the fact that a census in Uzbekistan has found >5,000 birds (Li et al. 2006), and only last year co-ordinated counts in Kazakhstan located >20,000 individuals (ACBK 2016). While some of these Kazakhstan birds will potentially migrate to known sites, and may be picked up during other mid-winter surveys, it is obvious that a large proportion of the population is not being recorded. This makes deciphering population trends very difficult, if not impossible, without further information. Until a clearer picture can be established, an estimated global decline of 50-79% in three generations is precautionarily maintained. Co-ordinated global surveys during winter are needed to clarify the overall population trend.
