men and women,
Lightly put it into the quiet valley Tianchi......
Under the starry sky of a bright moon,
on a tall branch,
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...
