Involuntarily he straightened up,
The pink face turned back,
The two hills covered in sweat kept shaking,
On a towering branch near the entertainment city,
a male bird,
swaying little body,
Gently flapping two wings,
vigorously inflating the throat sac,
chirping rhythmically,
standing quietly on the back of a female bird,
The female bird at this time,
is slowly removing its tail,
When arching the back,
only male birds,
Gently rub the female bird,
two birds,
In this delicate and intimate way of contact,
Having fun on the branches...
