There's less than a month left in my 100-Day Sketch Challenge, so for these next few weeks, I'll be drawing animal groups for only a few days to cover as much different species as I can before the end. Still continuing with the drawing-birds series, I'll be drawing waterfowls in the next few days. First up is the Chinese Goose. This domestic breed descended from the wild swan goose, which can be distinguish from other geese by the strongly developed basal knob on the upper side of the bill. These bird have exceptional hearing and eyesight, aggressive, extremely vigilant, very loud and very hard to shut them up, that they had been used like guard dogs by the police in some parts in rural China. They had been known to spread their wings and attack strangers entering someone's home. Beware!
