five or six, when their graceful gambols are very pretty to 

 see, though their cries are harsh. Their food consists 

 principally of flies, beeileSj and flying termites, and they 

 would appear to be at least partially migratory, for I have 

 not yet met with them during the winter months. 



20. Phylloscopls tkochilus. (Willow-Warbler.) 



Not uncommon, arriving from the north about October 

 and leaving in April. 



21. Geocichla HTSiTsiRUPA. (South- African Thrush.) 

 Not common, being generally found in small parties in 



the more secluded parts of the bush, where it seeks its food 

 upon the ground. The stomachs examined contained grass- 

 hoppers, pentatomid bugs, and beetles. 



22. TuRDUs LiBONYANUs. (Kurricliaiue Thrush.) 



This bird is very scarce in the open forests, but wherever 

 small streams overshadowed on either side by a line of dense 

 bush occur it is not uncommon. Yet in such localities 

 it is very difficult to obtain, as it is a wary bird and dives 

 into the densest thickets at the least sign of danger. It 

 feeds almost exclusively on tiie ground, eating coleoptera, 

 caterpillars, grasshoppers, small millepedes, and even seeds. 

 It has a short mellow song. 



23. MoNTicoLA ANGOLENsis. (Angolau Rock-Thrush.) 

 This species, which has been identified by Capt. Shelley, 



has not been previously recorded from south of the Zambesi, 

 though it is evidently resident here. It is not very common, 

 being purely sylvan in its habits, feeding on the ground in 

 the open bush, and taking to the trees immediately it is 

 disturbed. The first specimen I obtained was a male, which 

 vas singing pleasantly at the summit of a tall tree. As a 

 rule, this species appears to be solitary, but later in the 

 season family parties of four or five may be seen, feeding on 

 beetles, beetle-grubs, locusts, and ants. 



In 1894 I shot an example of another species of Rock- 

 Thrush at Salisbury, but could not then identify it, and 

 unfortunately the skin could not be preserved.
