2 ANIMAL LIFE IN AFRICA 



in the northern hemisphere, though individuals of certain 

 species are said to remain occasionally all the year in 

 the south, and nest there. Others again are purely 

 African types, which go no further north than the tropics 

 to spend the cold southern winter, and information 

 is required as to exactly where some of them go to. 

 As regards the European visitors, while some authorities 

 have maintained that the migrants from farthest north 

 wend their way farthest south, others suggest the re verse. 

 During the last few years some very interesting experi- 

 ments have been carried out among the white storks. 

 Societies in Germany and Hungary have adopted a 

 method of attaching aluminium rings to the legs of 

 young storks while still in the fledgling stage, with the 

 result that birds marked in Germany have been found 

 a few months later in north-eastern Rhodesia, Bechuana- 

 land, and Basutoland ; while others, which came from 

 Hungary, were discovered in Natal, the Transvaal, 

 Basutoland, and the Orange Free State. 



In order, so far as possible, to arrive at some rough 

 idea of the times of arrival and departure of various 

 kinds of migratory birds, the Transvaal Museum has, 

 for some years, been in the habit of sending to various 

 likely people in south Africa a list of species, with the 

 request that they will note, on a card sent for the purpose, 

 the date on which they first and last noticed each, 

 together with the direction of the wind at the time. 



Although the replies were unfortunately far fewer than 



might reasonably have been expected, still, enough were 



sent to form, even up to the present, very interesting 



data. Thus, white storks seem to begin to arrive about 



the middle of October, and depart from February onwards 



\ until April. European rollers '''arrive in October, and 



/leave in March. Bee-eaters %re resident from October
