196 Mr. F. A. Barrett's Notes on the Birds 
8. Milvus korschun. 
I first observed this bird near Kronstadt, but I did not 
manage to shoot it. I have since procured it in Potchef- 
stroom district, also near Rustenberg. I think I have seen 
it catching locusts with its feet; but the locusts were so thick 
that I could not observe the fact with certainty. 
9. Elanus cleruleus. 
Procured one near Rustenberg. It attracted my attention 
by a harsh cry, high in the air, which I thought to be that 
of an Eagle; but, to my surprise, I found it proceeded from 
this bird. 
10. Cerchneis tinnunculoides. 
I procured this bird near Rustenberg, also in the district 
of Potchefstroom. They feed on locusts ; and after feeding, 
they will sit on a high tree, occasionally cleaning themselves, 
in sleepy repose. 
11. Cerchneis rupicoloides. 
This Kestrel appears to me to be the commonest one in 
the Transvaal. I have shot it in the Lydenburg district, near 
Pretoria, Potchefstroom, Rustenberg, and on my journey from 
Bloemfontein to Potchefstroom. One day I had shot a Black 
Knorhaan, which skulked away in the grass ; and on turning 
my head I perceived a Kestrel (C. rupicoloides ) hovering 
within a few yards of the place. He came down, and a battle 
ensued; I, being anxious, ran to procure my bird, when the 
Kestrel flew off to a neighbouring bush; and while I turned 
to look at him the Knorhaan had gone. As I had not time 
to search for him I conclude the Kestrel had a good meal. 
They appear to be gregarious, as I have often counted nine 
or ten of them on one tree. 
12. Bubo maculosus. 
Very common in the Transvaal. I have shot and observed 
it between Bloemfontein and Potchefstroom, between the 
latter place and Rustenberg, and near Pretoria. The cracking 
noise they constantly make with their bill, more especially 
when wounded, at once distinguishes them from most of the
