Australian bowerbirds use Solanum ellipticum berries to decorate their bowers, and the more berries they use, the better their chances of mating. Joan Madden and team from Exeter University, UK, have discovered that the number of S. ellipticum plants near the bowers increases in the year after a bower is built. The bowerbirds are not intentionally cultivating the plant, but they are unintentionally creating 'gardens' round their bowers.
