Common on the open savannas. Usually seen in pairs. On the

This lapwing is thoroughly detested by the native deer hunters 

 from the habit it has of following, often for long distances, any one it 

 may see walking about among the little clumps of trees and bushes 

 that here and there dot the savannas, and screaming its displeasure. 

 The deer seem to understand that cry and are instantly on the alert.
