The bowerbird

Bower is named after the bowerbird, a family of birds where males build a structure [the bower] and decorate it with sticks and brightly coloured objects in an attempt to attract a mate. Bower does just that. Bower brings together bits and pieces from across the forest so you can build your structure.
