Habits. The Blue Knorhaan is found along the banks of 

 streams, and also on the open veld and on stony hills. It is not 

 so noisy as some of the other Knorhaans ; it is stated by some 

 writers to be somewhat shy and difficult to approach, except by 

 the well-known method of gradually circling round it. Millais, on 

 the contrary, found it tame and unsuspicious ; he also illustrates 

 its method of making off when alarmed, with its head lowered.
