- S2328 - 64: European breeding population 120,000 - 320,000 pairs (360,000-960,000 individuals). Estimate probably too high. Uncertain data from the principal breeding country, Ukraine, due to movement of colonies from year to year. Numbers wintering in Mediterranean much lower despite extensive surveys (F8a).
- S7270 - Cama et al. 2011. New estimate based on comprehensive surveys in winter. Former over-estimates caused by double-counting at shifting locations of breeding colonies in breeding stronghold of Ukraine.
- S2331 - 877. New estimate based on comprehensive surveys in winter. Former over-estimates caused by double-counting at shifting locations of breeding colonies in breeding stronghold of Ukraine.
- S8424 - A new population estimate was adopted by Delany and Scott (2006) based on a review of wintering data by Cama et al., 2011) suggesting 50,000-120,000 individuals after rounding and claiming that the main cause of discrepancy is an overestimation of breeidng numbers in UA. However, recently 15,155-24,134 pairs reported from the EU Members States, except CZ, and BY, CH, TR (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 310-340 pairs in AZ, CZ, RS&ME (BirdLife International, 2004). These two set of sources produce an estimate of 54,000-84,000 individuals without adding the estimate of 60,000 pairs, i.e. 180,000 individuals, estimate of Ardamatskaya (1999) the authors consider more reliable. However, even this estimate is 1.5 times higher than the upper limit of the estimate of Cama et al. (2011). However, for every other gull species well monitored in Europe, totals of wintering counts are always much lower than breeding estimates especially in case of coastal species. Therefore, the population estimate is revised based on the breeding numbers usingthe estimate of Ardamatskaya (1999) for RU and UA.
- T6423 - Overall trend derived from national trend estimates for breeding birds indicate a large increase (2000-2012: 1.0246-1.0813, 1980-2012: 1.0180-1.0420; European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.) without RU and UA where it is decreasing. It is also decreasing in BY and GR. It is increasing in AT, DE, DK, ES,, FR, HU, HU, IE, IE, IT, NL, PL, SK and the UK and stable or fluctuating in BE, BG, CH, SE and TR.
- S8976 - Current total 17,963-28,059 pairs excluding the uncertain estimates for UA. See CSR6 for further explanation.
