Satin bowerbird
The satin bowerbird builds a special area, called a bower, to attract a female. They return to the same area every year, where they clear a space about  in diameter and then build the bower. In the centre is two lines of thin sticks or grass, carefully lined up to north and south. He can paint the walls with a mixture of his saliva and crushed berries which he brushes on with a stick. He then places a collection of coloured objects in the entrance to the bower. These are usually blue or yellow, and can include feathers, and even plastic or glass. The male stands outside the bower and sings and may pick up the objects to show them to the female. If she is pleased with the performance and the bower, she will enter the bower, followed by the male and they mate quickly. She will then fly off to begin building a nest. The male has nothing more to do with her.
