different „Migration-Roads" and „Traces', to the winter-quarters. For the 

 purpose to investigate the problem of orientation, it is a very important 

 phenomenon, that one and the same species, according to the point on 

 which it reached the coast, is migrating along different ., Migration-Roads* 

 and „Traces". 



Those birds, which arrive at the east-coast travel along of this in 

 south-east direction to the neighbourhood of Corfu, where they cross 

 the straits of Otranto and along the peninsula of Calabria reach 

 Sicily and from here Tunisia. Some of them follow from here the 

 coast traveling eventually till S f a x, others the west-coast of Algeria, 

 some single Herons cross the west Sahara, where they most likely 

 take up again the „Broad Front" migration form and travel until Nigeria. 



This migration-road-trace is used by the following species : Larus 

 ridibundus, Totanus calidris, Nycticorax griseus, Ardeola ralloides, Platalea 

 leucorodia and most likely also Egretta garzetta and Phalacrocorax jjygmaeus. 



This trace might be denominated 



tria adriatica -orientális f tarentica, sicUiensiSf 

 fan esica-algerica, 



A scarcely frequented trace takes about Corfu another direction 

 and can be followed along the Ionian coast till Can di a. This trace 

 I should like to denominate. 



via adriatica-onnentalisj jonica. 



Along this the following birds are migrating : Larus ridibundus, 

 Totanus calidris, Nycticorax griseus and most likely Columba oenas, as 

 one specimen was shot at Baerat in Albany. 



Those migrating birds of Hungary, which breaking up in west-south- 

 west direction in „Broad-Front-Migration-Road'' form and reach the Adria 

 about Fiume, are flying on for the greatest part in „Migration-Road" 

 form, at the first to the opposite coast, most likely over Istria and 

 then in south-east, direction further on in greatest quantities along the 

 west coast, some of them not very far, from the coast itself and only 

 a few within the limits of Italy. Near Sicily this trace meets the East- 

 Adriatic one, nad they join to one trace, which I should like to denominate 



via adriatica-occidentaliSf sidíiensiSf tunisica-algeriea. 



This is the most frequented trace along which the „Migration-Road" 

 of the following species are running along : Larus ridibundus, Totanus 

 calidris, Pavoncella pugnax. Limosa aegocephalo,, Vanellus capella, Gallinago 

 gallinaria, Gallimda chloropus, Fidica atra,, Egretta garzetta,, Ardea 

 purpurea, Ardeola ralloides, Nycticorax griseus,, Stumus vidgaris, Turdus
