Crows are Artists too!

A B&W reproduction of my photo you find on page 211 in Josef H. Reichholf's book "Rabenschwarze Intelligenz: Was wir von Krähen lernen können" (Crow black intelligence: What we can learn from crows), March 2011

I took this photo of a crow's nest fallen down from a tree in 2002 in a suburb of Tokyo (Higashi-Yukigaya). Nearby was a dry clean where the bird probably found ample supply of exiting avantgarde construction elements. But I do not know, whether a storm brought the nest down or whether the bird only was experimenting not too successfully with futuristic designs for courtship.
