In March, the temperature in Sêrtar County of Ganzi Prefecture warms up and the snow melts gradually. Hearing the sound that a ruddy shelduck makes, spring is coming.

The ruddy shelduck has a unique way of courtship. They will keep chirping. The closer they get, the more they sing. Ruddy shelducks who have successfully courted are very faithful to their partners.

The ruddy shelduck looks like a wild goose and a wild duck. How to quickly recognize it? The answer is easy. It is called "Flying Roast Duck". When the ruddy shelduck folds its wings, the whole body is almost the color of roast duck, which is very recognizable.

Although its color is like roast duck, the ruddy shelduck is under China’s second-class protection. It is forbidden to eat the ruddy shelduck and illegal to hunt it.
