Another German Stork in South Africa .—We have 
received from Herr Thienemann, the Director of the German 
Ornithological Observatory at Rossitten, in East Prussia, 
intelligence of the capture of another of their marked Storks in 
South Africa. The Stork in question was bred on the property 
of Herr Adam Sobottka at Lyek in Eastern Prussia, and was 
labelled, on July 7th, 1907, with a small aluminium ring on 
one foot, on which was engraved iC Yogelwarte Rossitten, 
Germania, 769/” In the autumn of the same year it was 
captured by some bushmen in the Kalahari Desert. The 
aluminium ring, which seems to have been considered by the 
bushmen to have been of heavenly origin, passed into the 
hands of a trader on the northern edge of the Kalahari, who 
sent it, with an account of the way in which it had been 
obtained, to the Editor of ‘ The Wide World 3 in London. 
This and the previous instance, in which one of the marked 
Storks of Rossitten was taken in South Africa and identified *, 
seem to establish the fact that Storks bred in nearly the 
most northern limit of their range cross the whole continent 
of Africa to pass the winter months south of the Equator.
