Mr. Andersson says that this species is “rather scarce in Damara 
Land, and only makes its appearance during the rainy season.” It 
occasionally strays into the colony, following the locust swarms. 
On one of these occasions the pair now in the Cape Museum were 
obtained by Mr. Cairncross, of Swellendam, in 1860. He informed 
us that they were feeding on the locusts, and after gorging them- 
selves, perched on the summits of high trees, from which they were 
easily shot. On the 7th January, 1870, Mr. Cairncross wrote “ over 
the street (Swellendam), I to-day counted thirty-four of the little 
Kestrel drifting along westward about 200 feet over head. Locusts 
are plentiful this year.” Dr. Exton writes, ‘‘ North of Sechele’s I 
shot a pair of O. nawmanni out of a flock from which I also obtained 
C.rupicola. They were harrying a flight of locusts, taking them on the 
wing, striking them with their feet and then carrying them to their 
bills.” Mr. T. E. Buckley, during his journey to the Matabili, shot 
a young male on the Limpopo River, on the 14th of November, 1873.
