Black-winged Stilts in Britain: past, present and future Since the mid 2000s, there has been an increase in numbers of, and breeding attempts by, Black-winged Stilts in Britain. In general, influxes of Black-winged Stilts into Britain have typically followed dry conditions in southwest Europe in spring but, for a given level of drought in southwest Europe, more stilts are now reaching Britain. This change perhaps reflects the increasing numbers now breeding in northern France. Most breeding attempts by stilts in Britain have been on nature reserves, but overall breeding productivity has still been low.

Changes in the numbers of Common Guillemots on Skomer since the 1930s Photographic evidence shows that the breeding population of Common Guillemots Uria aalge on Skomer, Pembrokeshire, in the 1930s was considerably larger than it is today, and may have comprised around 100,000 individuals. A substantial decline occurred between 1939 and 1946 and is thought to reflect wartime oil pollution, a previously unrecognised effect of the Second World War on UK wildlife.
