This video is called Zebra finch in the nest.
According to the Dachverband Deutscher Avifaunisten, three new bird species are now nesting in Germany.
They are: muscovy duck (see also here), originally from South America; and zebra finch, originally from Australia.
Pink-footed geese are not as new to Germany as the two other species, as they have been wintering in central Europe for ages. However, that they nest now near Mannheim in southern Germany, not just in the Arctic, is new.
This is a video about pink-footed-geese in Norway.
