 abstract={The proportion of different nest predators robbing nests of the Collared Flycatcher Ficedula albicollis population breeding in natural cavities in the Białowieża National Park was studied during 1988-1998. Robbed nests were examined thoroughly for signs betraying the predator. Mustelids, (mostly the Pine Marten Martes martes) destroyed no more than 25% of the Collared Flycatcher nests, while rodents (mostly Yellow-necked Mouse Apodemus flavicollis), and woodpeckers (Great Spotted Woodpecker Picoides major) were together responsible for the destruction of c. 75% of all the Collared Flycatchers broods. Rodents destroyed significantly more nests with eggs, whereas woodpeckers and Pine Marten destroyed mostly broods with nestlings.},
