The Egyptian Vulture is one of the most endangered raptors in Europe. Illegal poisoning and habitat loss are a constant threat in many areas.
Another threat are high levels of toxic substances in the birds, like pathogens of poultry and pigeons, antibiotics and non-steroidal antiinflamatory drugs. Those substances have been found in Egyptian Vultures in Bulgaria. (see here for details).
In order to find out more about that problem, this year, BSPB (Birdlife Bulgaria) did a made toxicology sampling of all 25 unfledged juvenile vultures this year. Also, all birds were ringed.
The toxicological samples will be analysed in Madrid, Spain. The final results of this study will be published in 2010.
The Egyptian Vulture has declined dramatically in Bulgaria. From 2003 to 2008, the species declined from 57 to 35 pairs. The high levels of toxins probably play an important role in the species’ decline.
