> Recently, a mass-invasion of bramblings (Fringilla montifringilla) is
> taking place alongside the hills of the Ruhr Valley between Bochum and
> Duisburg. Today I have seen seemingly never-ending ribbons of birds
> swirling through the crowns of the beech-forests. No serious attempt of an
> estimate can be made here, since each calculation ends between 1.5 an 5
> millions of bramblings.
> Two days ago, West German Television and WDR-broadcasting sent the news of
> approx. 1.3 millions of bramblings in the South of Essen. Observers say it
> was most expressive.
> This invasion has been lasting at least since 29th january, the first
> hundreds of thousands of bramblings being reported from the woods near
> Muelheim. Ornithologists in the mountains of the "Sauerland" calculate
> their wintering birds at a total of 200.000 to 250.000, which they are now
> missing, as a blanket of half a meter of snow covers the earth.
> This seems to be a lifetime´s record as from 1906 on (Otto Le Roi) no
> single observer has reported quantities like this from the Rhineland and
> Westphalia.
