Nest predation

Danaë K. Stevens et al.: Predators of Spotted Flycatcher Muscicapa striata nests in southern England as determined by digital nest-cameras
Bird Study, 55:2, 179-187

Nest-cameras can be useful in the identification of nest predators, and may be deployed with no effect on nest survival. Most predation of Spotted Flycatcher nests in this study was by avian predators, principally Jays. There was little evidence of predation by mammalian predators.
