Population estimates of wintering waterbirds in Great Britain This paper provides updated estimates of population size for wintering waterbirds in Great Britain using recent data and new analytical approaches for some species that use smaller inland waterbodies or the non-estuarine coast. Overwinter population estimates are presented for 98 species or populations.
Eastern Orphean Warbler on the Isles of Scilly: new to Britain On 12th October 2017, an Orphean Warbler Sylvia hortensis/S. crassirostris was discovered on St Agnes, Scilly.

Bird hunting in Europe: an analysis of bag figures and the potential impact on the conservation of threatened species Official hunting statistics from 24 EU member states as well as Switzerland and Norway were collated. The results show a total annual hunting bag of at least 52 million birds. The bag figures for certain species, such as Common Pochard, Northern Lapwing, Turtle Dove and Skylark, remain high in proportion to their declining populations in Europe. Hunting pressures may be undermining conservation efforts undertaken for these species.
