Analysis of the consistency of the change in range size (ΔRS) and change in weighted mean latitude (ΔWML) between the two study periods covered by the three atlases of Finnish breeding birds of 34 northern species (upper panels a and b) and 114 southern species (lower panels c and d).

<p>In all panels the change in the latter pair of atlases (atlas 2 vs atlas 3) is plotted against the change in the former pair of atlases (atlas 1 vs. atlas 2). The correlation between these two changes was never statistically significant (see Results).
