REPORT ABOUT THE HUNGARIAN BIRD BANDING WORK. 77 



musiciis, Oriolus galhula, Alauda arvensis, Milvus ictimis. Of the above 

 mentioned species Ardeola ralloides^ Nycticorax griseus and Egretta 

 garzetta are also to be found in Nigeria, but this can't be expressed 

 in the denomination of the migration road trace, because from the 

 north-african coast the further flight of birds seems to proceed not in 

 migration road but in broad-front-road from. The smaller part of those 

 birds, which reach the Adria near Fiume or Trie s t is leaving the 

 till now" followed West-Adriatic trace and is traveling along the Po and 

 the coast of the Mediteranea and remains for the winter in Spain. This 

 trace which I should hke to denominate: 



via padana f I Uj urica, hispanica 



unites the migration roads of following species: Larus ridihundus^ 

 Hydrochelidon nigra, Plegadis falcinellus and especially Vanellus capella. 

 Out of this trace is turning a rather sparely frequented branch to the 

 Tyrrhenic coast and unites only the migration roads of Larus ridibundus, 

 Vanellus capella and Fulica atra. This trace I should like to denominate 



via jiadana, tyvrhenica 



this may hardly reach Sicily. 



The circumstances of migration are so complicated that, in spite 

 of a thorough description I am not able to reproduce every thing 

 concerning it, quite truly. Just so, in the denomination of the above 

 mentioned 5 migration road traces, the fact is not included, that a not 

 very small part of those migrating birds which travel along of them, are 

 staying already on certain parts of their way, for the winter, so that the 

 migration-roads and especially the traces are lasting partially also in to 

 the winter quarter. Not every bird of one specimen is traveling to the end 

 of a migration-road. 



All the hitherto discussed migration-roads are refering to the migration 

 in autumn. Wether the migration in spring is going on, on the same 

 migration-roads or traces is in default of sufficient particulars as yet 

 undicided, but it is not probable. Most likely our migrating birds are 

 travehng in the spring in broad-front-form towards their native country. 

 A small hint concerning this is, that the most scantily frequented via 

 Tyrrhenic is much offener taken in spring and that, after a few observations: 

 from the sea side. Only the White Stork seems to keep also in spring his 

 well known migration-road of the autumn. Also in other migration districts, 

 where birds were banded, it is just the migration in spring, w^hich has 

 been cleared up in a much smaller measure than the migration in autumn 

 and I schould like to. emphasize it most energetically that by the greater 

 part of the species, the migration in spring is utterly different from that
