5.3.13 Black-headed Gull
5.3.13.1 Abundance estimates 76.
Black-headed gulls were recorded in April, July and November 2012 (Table 5.19). Numbers peaked during July 2012 when an estimated 313 (199 - 428) individuals were present within the East Anglia THREE site. Monthly abundance estimates for the East Anglia THREE site with a 4km buffer are presented in Appendix 3, as the raw count data and confidence limits for the monthly abundance estimates.

The abundance estimates below provide information on this species after there has been the process carried out of the attribution of unidentified birds, the process of attribution being described in the methods section. Appendix B provides the abundance estimates for this species before the attribution of unidentified birds and also the abundance estimates for the relevant unidentified, grouped category.
