Massive numbers of migratory birds never make it to Africa at the end of the European summer because they fall prey to hunters along the way, especially in the countries of the Western Balkans, which lie on one bird migration route.
In Bosnia-Herzegovina, for example, migratory birds have been hunted for many years. In recent years, the country has become a popular destination for hunters from abroad. A growing number of agencies in the country organize hunting trips for Italian citizens.
This increase poses a threat to a variety of species, including quails, which are particularly popular with hunters.
In some cases, although hunters have the requisite permits, illegal devices are used to attract birds to the hunting grounds.
Activists say that countries like Bosnia-Herzegovina are popular with foreign hunters because the laws there are considered easier to evade.
A group of journalists including DW's Ajdin Kamber set out to investigate the use of illegal hunting methods in Bosnia-Herzegovina and the prosecution of those who break the law.
