The bank vole (Clethrionomys glareolus) is a small vole with red-brown fur and some grey patches, with a tail about half as long as its body. A rodent, it lives in woodland areas and is around 100 millimetres (3.9 in) in length. The bank vole is found in much of Europe and in northwestern Asia.
In North America and most of Europe, voles predominate in the diet, and shrews are the second most common food choice. [24] In Ireland, the accidental introduction of the bank vole in the 1950s led to a major shift in the barn owl's diet: where their ranges overlap, the vole is now by far the largest prey item. [32]
Voles outwardly resemble several other small animals. Moles, gophers, mice, rats and even shrews have similar characteristics and behavioral tendencies. Voles thrive on small plants yet, like shrews, they will eat dead animals and, like mice and rats, they can live on almost any nut or fruit. In addition, voles target plants more than most ...
Salmon is high in omega-3s, which is an important part of any balanced diet. ... Rich in potassium and shown to improve blood pressure, red snapper is an option to add to your healthy meal plan.
The common vole is one of the most important foods for Eurasian eagle-owls. In the northern extremes of their range, Eurasian eagle-owls tend to have a less varied diet than those to the south and the need to catch significant numbers of rodents rises as they are often the only regularly accessible prey in sparse sub-Arctic environments.

The most convenient distinguishing feature of the Arvicolinae is the nature of their molar teeth, which have prismatic cusps in the shape of alternating triangles. These molars are an adaptation to a herbivorous diet in which the major food plants include a large proportion of abrasive materials such as phytoliths; the teeth get worn down by abrasion throughout the adult life of the animal and ...
Other records from Russia and Ukraine show voles ranging from slightly secondary prey to as much as 42.2% of the diet. [100] In Belarus, voles, including Microtus species and 18.4 g (0.65 oz) bank voles (Myodes glareolus), accounted for 34.8% of the biomass on average in 1065 prey items from different study areas over 4 years.
