128 PICID^ CAMPOTHEKA 



and shrubs, Symonds noticed them on the lowest branches of the 

 mimosa trees near Kroonstad, and Stark flying from one Protea bush 

 to another in the French Hoek mountains of the Paarl division. 

 Their note is loud and not unmelodious, though Burchell compares 

 it to the sound made by filing the teeth of a saw ; their food consists 

 entirely of ground-living insects of various kinds which they search 

 for with their strong beaks in the crevices of rocks and underneath 

 stones ; they appear to be early breeders throughout their range ; 

 Stark found a nest on August 12 near Wellington, and Butler one 

 on August 2, near Newcastle in Natal ; a bank is usually chosen, 

 into which is bored a tunnel running slightly upwards from the 

 entrance, for about eighteen inches to several feet ; at the end of 

 this, in a slight depression without any nest, are laid 4-5 white eggs, 

 somewhat rounded in shape and measuring about I'O x 0-85.
