In early spring 2014 I found an old nest of Golden Oriole / Pirol (Oriolus oriolus) in a poplar tree, ca. 10 metres above the ground, south of Podersdorf, Austria. As far as I could see (and is recognizable on the photo), it was built mostly from white plastic ribbons. These were used in a vineyard just a few metres away from the nest, to tie vines to poles. This was very surprising to me, but a google image search for „pirol nest“ revealed that plastic parts are commonly used as a nest-building material by this species. Photo of the nest taken with digital camera through spotting scope.
