The review shows that in the African-Eurasian region alone, hundreds of thousands of birds die annually from electrocution and tens of millions of birds from collision with power lines. In general, large birds seem to be more affected. For some large, slow reproducing bird species which migrate across this region, such as pelicans, storks, flamingos, birds of prey, cranes, bustards and owls, the death toll could possibly lead to population declines and/or local or regional extinction.
