In western Switzerland, the diet was similar but far more homogeneous, with Apodemus species at 74.3% and bank vole at 18.7% among 10,176 prey items. [ 63 ] The northernmost food study for tawny owls thus far conducted showed that in Sweden , field voles were the main food amongst 578 prey items, at 30.5%, with bank voles being supplemental at ...
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.
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 ...
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 ...
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]
The Clethrionomyini are a tribe of forest voles in the subfamily Arvicolinae. [1] This tribe was formerly known as Myodini , but when genus Myodes was deemed to be a junior synonym, the tribe was renamed. [ 2 ]
The western red-backed vole plays an important role as prey to a number of species, including martens, ermines, and long-tailed weasels. [3] The red tree vole, northern flying squirrel, and western red-backed vole may constitute more than 75% of the northern spotted owls diet. [5] No fossil remains have been identified yet. [3]
It is the largest species in the subfamily Arvicolinae, which includes 142 other species of rodents, mostly voles and lemmings. Muskrats are referred to as "rats" in a general sense because they are medium-sized rodents with an adaptable lifestyle and an omnivorous diet. They are not, however, members of the genus Rattus.
