The mechanisms driving 3–5-year population cycles of voles involve delayed density-dependent feedback on vole populations. The key drivers of this feedback include prolonged periods of food depletion or predation mortality over more than one phase of the cycle. We review observational and experimental data gathered between the 1970s and 2010s on vole population fluctuations and the responses of their avian and mammalian predators in west-central Finland, focusing on studies that have investigated these drivers. This document includes data used for the figures of the article. https://doi.org/10.1002/ece3.71419
