An episode of mortality in waterbirds occurred on a sedimentation reservoir with effluents from the sugar beet processing plant at Hrusovany n.J. (South Moravia, Czech Republic) in summer 2003: tens of black-headed gulls (Larus ridibundus), several lapwings (Vanellus vanellus), one little ringed plover (Charadrius dubius), one ruff (Philomachus pugnax), one wood sandpiper (Tringa glareola), and two avocets (Recurvirostra avosetta) died. One of the two avocets and the plover, local breeders, were examined and found positive for Clostridium botulinum type C toxin by use of the toxin-neutralization test. Avocet is classified as a rare bird species according to Red Book data and is listed as critically endangered species in theCzechRepublic, and is therefore protected. Avian botulism can occasionally cause deleterious effects to waterbird fauna and its protection.Keywords:
