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.

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 ...
The bank vole was probably introduced by humans at some time after the last glaciation. It is one of four small mammal species on Skomer. There are approximately 20,000 voles on the island. [1] The vole's main predators are owls, but it is also eaten by other predators, including common kestrel, common buzzard and peregrine falcon. [1]
Bank vole is a common prey. The tawny owl hunts almost entirely at night, watching from a perch before dropping or gliding silently down to its victim, but very occasionally it will hunt in daylight when it has young to feed.
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 ]
On the Cape Verde Islands, geckos are the mainstay of the diet, supplemented by birds such as plovers, godwits, turnstones, weavers and pratincoles. [23] 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. [24]
