Popis: In recent decades the number of breedingpairs of the curlew has decreased in Westfalen (North-West Germany) as well as in the whole Federal Republic of Germany caused by permanent change or destruction of the environment. The hatching success decreased because of breeding in subideal habitats like fields resulting in starvation and reduced mobility to escape predators. In the District of Steinfurt (Westfalen, Germany), members of the {open_quotes}Workinggroup Wetmeadows{close_quotes} recognized decreasing hatching success of individually marked birds during several years. The burden of PCBs or other chlorinated compounds was hypothesized as a possible cause of this decrease. 18 refs., 4 figs.
