Long-term trend
UK, England: fluctuating, with no long-term trend
Status summary
The decline in the late 1960s and early 1970s was thought to be due to severe drought conditions in the Sahel wintering area in Africa (Marchant et al. 1990). There was a loss of range of 20% in Britain between 1968-72 and 1988-91, in terms of the numbers of occupied 10-km squares (Gibbons et al. 1993). A recovery in population size began in the mid 1970s and appears to have continued, at least in England, into the late 1990s. This increase has been associated with improving breeding performance and progressively earlier laying dates. The trend towards earlier laying can be partially explained as a result of recent climate change (Crick & Sparks 1999).
