Bower Birds.

Bower Birds are cool.....really cool. They set an example for all males when trying to seduce females. They practically invented the idea of the "Batchelor Pad".
To attract mates, Bower birds build incredibly complex nests (called Bowers) which are adorned with flowers, fruit, nuts and beetle shells for decoration. Instead of using bright colours which most of the paradise birds are born with, Bower Birds opt for being creative about things and so they design and decorate perfect living conditions for themelves. They are obsessive about how their bowers look, and if you mess up their bower by say, putting flower petals that are a different colour in the bower, they will immediately fix things back to the way they were. These birds are tidy, and they like to co-ordinate everything. If they believe that females would prefer pink flowers to blue, they will decorate the bower with only pink flowers. Even objects of the same colour are used to decorate the nest, like pebbles, plastic or glass. Its all about their personal choice.

Now that is flagrant living. Check out this clip from David Attenborough.
