Shit happens not only to mammals, but to birds as well. This poor tufted duck (Aythya fuligula) somehow managed to put a rubber ring over its body.
Tufted duck (Aythya fuligula) caught in rubber ring
I wonder if this possibly already happened when the duck was still not full-grown or if it was already full-grown. Like the last photos this specimen was also photographed at the Danish Museum for Hunting and Forestry at Hørsholm.
