Darwin
Imagine a highly industrialized landscape, only consisting of concrete, steel and asphalt. Small strips of grass have to compensate for the pollution caused by dense traffic and exhaust pipes. Now imagine a slightly eccentric pigeon, whose fight for survival could be only interpreted by humans as a work of art.
In February 1997, an iron pigeon nest was discovered by workers at the Esso oil refinery, Rotterdam. Dutch biologist extraordinaire Kees Moeliker was called to the case and had to conclude that this iron nest was indeed built by a pigeon, using steel wire and feces.
