Notes

  • S2232 - 64: European breeding population of Caspian Gull and Yellow-legged Gull 310,000-580,000 pairs (930,000 - 1,740,000 individuals).
  • S8413 - Earlier estimate concerned L.c. cachinnans and L. m. michahellis combined. 31,551-49,967 pairs in BY, DE, HU, LT, PL, RO, RU, SK, and TR (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.) and further 22,800-33,530 pairs in AZ, GE, UA and MD (BirdLife International, 2004). This yields a total estimate of 163,000-250,000 individuals after rounding, but the population also includes an unknown number of birds from Central Asia. Assuming minimum as many as the minimum for European RU and maximum as many as the entire European population, the total size might be 200,000-500,000 individuals. The breeding numbers agree closely with the sum of the wintering numbers from BG, BY, CH, CY, DE, GR, LU, RO, RU, SE and TR (149,240-271,229). However, birds in the Middle East are not included, but it can make up 20-30% of gull gatherings in the Gulf (Olsen 2010).
  • T6412 - Increasing in every country which made new trend estimates (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.).
  • S8967 - 54,051-87,487 pairs in Europe (BirdLife International 2015). Robust population estimates for C Asia are lacking (Sheldon 2017).
  • T7041 - Increasing in most European countries, but trend in C Asia is unknown.
