Will the ring injure the bird? The ring does not hurt the 

 horny piates of the leg (even if it will smooth them a little), and 

 I have never had any proof of its causing the bird to stick any- 

 where. Nor is the ring so heavy, that it will check the tlight of 

 the bird (I have e. g. often watched hatching ring-starlings flying 

 about in the vicinity of mj' home). And it is not so conspicuous 

 that the bird should be persecuted on account of it. 



Associates are named p. 111. The Carlsberg Fund has three 

 times granted me an assistance (p. 112). 



Instruction to assistants is sent, if verbal instruction cannot 

 be given. Bands when 1 mm. thick are cautiously applied to the 

 bird's leg with flat-nosed pliers, when 2 mm. thick with a screw- 

 wrench, the jaws of which can be screwed together by turning the 

 handle. It m^y be recommended to cover the bird's head with a 

 dark cloth. 



Correspondence with the spor Ismen. To the gentleman 

 who informs me of a ring-bird, are sent 



1) A short information about the purpose of my ringing experiment, 



2) Sketch maps with indication of piaces where ringed birds have 

 perished, and the names of the reporters, 



3) Schedules with questions: when and where was the bird killed? 

 Has the ring injured the foot? etc. The reporter is asked to 

 send an impression of the ring (instructions how to make it 

 are given), while the ring itself or the stuffed bird has better 

 be kept in the sportsman's country as a proof that the bird 

 was shot there. 



These papcrs are printed in Danish, or German, English or French. 



The returned filled-in Schedules are bound. 



At my request some foreign sportsmen have kindly mentioned 

 my experiment in the daily press of their countries. Gratuities are 

 only paid if demanded. 



Enumeration of the marked birds and the reports vide 

 p. 120. The game-birds have given the best results, the Startings 

 the poorest ones. As soon as the fence-months of the Starlings are 

 reduced to the summer, or it is permitted to net and mark them 

 in winter, more information of ring-starlings will be received. 



Results. Teal (Anas crecca) have been followed from their 

 breeding piaces in the north of Sweden to the western part of Eu- 

 rope and the Mediterranean countries; Buzzard (Biiteo vulgaris)^ 

 Kite (Milvus ictiims). Starting (Stiirnus vulgaris) and Heron (Ardea 

 cinerea) have also passed S. W. Stork (Ciconia alba) is followed 

 to the south-east through Prussia and Hungary and is found again 

 south of Tanganyika and in the Transvaal. In the immense regions 

 between these piaces storks marked with rings from Rossitten and 

 Ungarische Ornithologische Ontrale have ])erished. It is a fine re- 

 sult of international research. When once migratory birds are
