Estimated total number of breeding individuals of native breeding bird species (millions) in (a) the UK from 1966 to 2018, and (d) EU from 1980 to 2017, with shaded 95% credible intervals. Overall net change (green shading) in individuals for the UK (b) and EU (e) with 95% credible intervals (ibeam), derived from total increases among species with positive trends (pale blue) and total decreases among species with negative trends (darker blue shading). Frequency distribution of species' log-transformed average annual rate of change for species in the UK (c) and EU (f), the dashed vertical lines indicate the median value. (Online version in colour.)
