Out of a nonbreeding group of cranes, 10 birds died peracutely at the end of April 1998. The pathological investigation showed changes in the intestine, liver and kidneys caused probably by an intoxication; but corresponding analyses did not result in a specified poison. The proof of E. coli, Cl. perfringens and Campylobacter jejuni is to be interpreted as a subordinate result. 7 of 8 cranes had a low to high infestation with endoparasites (Porrocaeum spp., Eimeria pusilla, Echinostoma spp.). 5 of 8 birds showed leaness, possibly as a result of the migration exertion. Further on, the analysis results of a 9th crane found at another place are included in this paper.
28 species of parasites (8 coccidia, 6 trematodes, 1 cestode, 6 nematodes, 1 tick, 6 mallophages) were found at the Common Crane. After presenting the interconnection of parasites with different carriers as vectors, intermediate and several final hosts in the biocoenosis of Common Cranes, the results of parasitological examination of 421 samples of cranes resulted in varying parasitization at different seasons and flyways. Further studies are needed to interprete these facts correctly. Changes of presented localities of diverted feedings and their parasitological and bacteriological control at resting places may avoid concentration of pathogens in soil, intermediate hosts and carriers.
