Abstract
Stomach content analyses performed on 272 meadow voles (M. pennsylvanicus) revealed that the animal feeds on 35 of the 45 spp. of plant present in its habitat. Timothy is the most abundant and the most common plant in the vole''s diet. The abundance of the plants sampled in the habitat is positively correlated with the abundance of the plants found in the stomach contents. Some species, like meadow grass (Poa spp.), are definitely preferred by the voles since they appear more frequently in the stomach contents than in the habitat. Some feeding habits are also sex dependent.
