Long-term trend
UK: Rapid increase
 
Status summary
Nuthatch abundance has increased rapidly since the mid-1970s, although BBS data suggest that the upward trend may now have ceased. This increase has been accompanied by a northward range expansion (Gibbons et al. 1993) and has been associated with a large increase in brood size. A trend towards earlier laying, perhaps as a result of climate change (Crick et al. 1997), has also been identified..
