Mr. Guy A. K. Marshall on 
live or six, when their graceful gambols are very pretty to 
see, though their cries are harsh. Their food consists 
principally of flies, beetles, 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. Phylloscopus trochilus. (Willow-Warbler.) 
Not uncommon, arriving from the north about October 
and leaving in April. 
21. Geocichla litsitsirupa. (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. (Kurrichaine 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 the ground, eating coleoptera, 
caterpillars, grasshoppers, small millepedes, and even seeds. 
It has a short mellow song. 
23. Monticola angolensis. (Angolan 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 
was 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.
