Another visitor.

This time, it's a female.

This is just where he wants her.

Time to begin the show.

First, he expands his pupils alternately.

It's an oddly mesmerizing display.

A spot of limbering up, accompanied by a weird and wheezy call from deep in his throat.

Now it's time for his grand performance.

He waves his wing like a matador's cape.

She appears to be transfixed.

This is certainly eye-catching, but it seems he needs to do more.

Generously, she drops him a hint.

It's the bird equivalent of a bouquet of flowers.

It's all going so well, it's time to get physical with a few head-butts to her chest.

One final flourish to cap weeks of effort.

But something's wrong.

His rival is back, and at the worst possible moment, what should he do?

For the female, the moment has gone.

Sometimes, whatever you do, things just don't work out.
