Female satin bowerbirds are less fussed about the size of their cock and more concerned about his ability to acquire blue trinkets. Males hunt high and low to scatter the floor of their bower with anything blue they can get their beaks on – from flowers to feathers to plastic bottle tops and clothes pegs. As if this weren’t surreal enough, they have even been known to paint the walls by holding a bit of bark coated in chewed up berries in their beak. Dalí would be proud.
