Abstract
Alternative calls of Common Chiffchaffs Phylloscopus collybita in the surroundings of Solothurn, Switzerland. In the literature, the autumnal migration call of young Common Chiffchaffs Phylloscopus c. collybita is described with a plaintive, disyllabic «sweeoo» or similar. In the surroundings of Solothurn in western Switzerland, birds with this call type were not present every autumn and winter. In autumn 2008, with mostly continuous winds from NE, such calls were heard very frequently. Whether this call type is uttered just by young birds or also by adults from eastern populations or dialect areas is not known. Remarkablyy about half of the breeding birds uttered the «sweeoo» call in the breeding season 2009 around Solothurn. Both in 2010 and 2011 this call was not heard any more from breeding birds.
