Abstract
Abstract The lesser kestrel (Falco naumanni) was considered extinct as a breeding species in Bulgaria, but recently a small breeding colony was found again in the south-eastern part of the country. Seven recent observations of flocks or solitary birds of the species in Bulgaria during the post-breeding period are presented and commented here. It is shown that the territory of the country is a regular area for post-breeding dispersal and pre-migratory feeding of lesser kestrels. The origin of these is not known, but most probably birds from the populations of the European part of Turkey, Greece, Republic of Macedonia and Albania are involved.
