In 2006, an emaciated female peregrine falcon Falco peregrinus was found near its nest, and died soon after. Parasitological research involved digestive tract and respiratory system, kidney and liver. In air sacs, nematode Serratospiculum tendo (Nitzsch, 1857), which causes the falcon disease serratospiculiasis, was found, and in the digestive tract trematodes Strigea falconis Szidat, 1928, Conodiplostomum spathula (Creplin, 1829), and a cestode Cladotaenia cylindracea (Bloch, 1782)
