1980s) and present<br />

breed<strong>in</strong>g distribution<br />
of each bird species,<br />

<strong>in</strong>clud<strong>in</strong>g range<br />
changes and trend<br />
between each time<br />
period. Range change<br />
was also calculated<br />
on the basis of a<br />
50km x 50km grid for<br />
comparability with<br />
1980s Atlas data. The<br />
quality of species<br />
distribution data <strong>in</strong><br />
Russia is poor, due<br />
to low coverage, and<br />
therefore Russia was<br />
not <strong>in</strong>cluded <strong>in</strong> this<br />
analysis.<br />

the year at which the population size of each species<br />
was at its lowest po<strong>in</strong>t (Figure 4). Raptors tended to<br />
show a lower yearly growth rate than waterbirds<br />
(4.7% and 5.9% per year on average, respectively)<br />
and variability tended to be higher among waterbirds<br />
than among raptors. White-headed duck<br />
showed the largest rate of <strong>in</strong>crease (13% per year) and<br />
Red kite showed the lowest (
