Another German Stork in South Africa. — We have 

 received from ITerr 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 '' Vogelwarte 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 ' 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.

 Journ. xxxiii. p. 40), will be found the following description 

 o£ the arrival of the spring-migrants at Cape Danmark,
