Аннотация: We developed different techniques for protecting avian broods in nest-boxes from potential predators. Twelve nest-boxes with nestlings were transferred from their initial sites on trees to tripods of original construction. All parental birds resumed feeding the chicks shortly after change of nest-box location. Almost all the broods successfully flew out of the relocated nest-boxes, only one of them was predated, presumably by a flying squirrel. To assess the protective properties of experimental nest-boxes fixed on tripods and hanged on ropes, we placed strips of copy paper on them as well as on control nest-boxes fixed as usually on trees, and recorded the traces of all visitors. The traces of birds were found on the nest-boxes of all types. At the same time, the traces of small rodents which perform potential threat for broods of small passerines were detected only on the control nest-boxes.
