REPORT ABOUT THE HUNGARIAN BIRD BANDING WORK. 75 



Wave"", if the breaking up occurs suddenly and in great masses from a 

 breeding district. In the case that such single migration roads are united 

 on a larger extent, so that individuals of different countries arrive at a 

 common winter-quarter, or if they pass the winter already on certain 

 spots of the common road, leading to the winter-quarters we get the so 

 called „Migration-Road". Through the concentration of the migration roads 

 of different species, we get the: „Migration-Road-Trace". 



The denominations of the adequate communication unities would be 

 .Paths, Ways and Roads". If we should accept these denominations or 

 this nomenclature for the traveling- way of the single individual or flight, 

 the word .Migration-Paths" would result. Out of the concentration of such 

 -Migration-Paths'* we should obtain the „Migration-Ways" and at the end 

 the word ^Migration-Road". The word „Migration- Way" could by no means 

 awaken in me the notion of the till now usual name of „Migration-Road", 

 on the contrary it seemed only to be the single way of an individual^ 

 therefore I decided to keep the word „Migration-Road" and to search for 

 an appropriate expression which might clearly explain the occurence of 

 the unition of several such „Migration-Roads". I thought at first of the 

 word „Track", but this expression was, objected and not without cause 

 by Geyr, besides the defining expression ..Migration" or ..Flight" was 

 missing out of it. Geyr proposed the word : „ Migrati on- Way of the masses", 

 but it seems to me, that it neither explains the occurence clearly, 

 especially if at such places there is no migration by the mass at all, 

 only at the most, a more lively flight. I should like now to propose the 

 word: „Migration-Road-Trace", though it does not sound very well. 

 I leave it undecided, wether this appropriate, if not very pleasing word 

 will be adopted, or wether somebody else \Aall find a better definition and 

 with it make also possible the consohdation of the whole system. 



To illustrate the migration roads of hungarian migrating birds, espe- 

 cially of these „Migi'ation-Road-Traces", I constructed on the base of the 

 places, where the banded birds have been captured, the sketch of a card on p. 53 

 on which the probable „Migration-Roads" and „Traces", of Hungarian birds 

 are made evident, which leave us in south-w^est direction in autumn. 

 The only bird breaking up in south-east direction, till to the north-east 

 bay of the Mediteranean and then migrating in almost exactly south 

 direction to the South-African winter-quarter, is the White Stork. 



All the other migrating birds of Hungary, of which the migration 

 roads were stated through the banding experiment, break up in west- 

 south-west to south-west direction and travel on in ..Broad-Migration- 

 Road" form till they reach at some point the coast of the Adria. 



Once arrived there, the „Broad- Front-Migration" kind of way is 

 changed and the birds travel on in ..Migration-Road" form along the
