Bowerbirds have and eleborate ritual for choosing a mate
First the male bird builds a bower a structure made of twigs
Second a female bird visits the bowers when the males are not there and inspects them
Then if a female likes a bower, she visits a second time when the male is at home
On this second visit, he entertains her with a special dance and a song
The female then goes to another bower to see another male dance
After she sees all the males dance , she leaves for a week to build her nest
Finally she returns to the bowers of her favorite males for a third visit , and chooses her mate.
