Field Vole 2

Voles depend on their camouflaged runways as they are the popular prey and main staple of many animals such as the barn owl. Like lemmings, field voles have peak years which mark population explosions. There have been field vole plagues, when the numbers were outrageously high. The overcrowding will lead to a natural slump in breeding when the population explodes. Field voles are found in North America, Europe and northern Asia. [BM] {FW}
