Long-term trend
UK, England: rapid increase
 
Status summary
Nuthatch abundance has increased rapidly since the mid 1970s. Despite minor setbacks during the 1990s, there is no indication yet of a halt to the upward trend. This increase has been accompanied by a range expansion into northern England (Gibbons et al. 1993) and has been associated with a large increase in brood size. The reasons for these changes are unknown. A trend towards earlier laying, perhaps as a result of climate change (Crick et al. 1997), has also been identified.
