The St Kilda house mouse (Mus musculus muralis) is an extinct subspecies of the house mouse found only on the islands of the St Kilda archipelago of northwest Scotland. [1] They were first described, alongside the St Kilda field mouse, by natural historian Gerald Edwin Hamilton Barrett-Hamilton in 1899.
In years of average population sizes, typical eastern meadow vole population density is about 15 to 45 eastern meadow voles per acre in old-field habitat. In peak years, their population densities may reach 150 per acre in marsh habitat (more favorable for eastern meadow voles than old fields). [8]
It is generally twice as heavy as field mice found on the mainland, [2] with a mass of between 50 grams (1.8 oz) and 70 grams (2.5 oz), and has longer hair and a longer tail. The evolution of a larger size has been credited to a lack of predators in its island habitat , [ 5 ] which allows the mice to grow larger to preserve heat and increase ...
The mice's squabble, Rowley later commented, was "over in seconds". [7] The photograph was chosen from a shortlist of 25 out of 48,000 submitted images. [1] The Director of the Natural History Museum, described the picture as showing "a fascinating glimpse into how wildlife functions in a human-dominated environment."
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 other small animals, making their presence evident.
Field mouse, in Europe, Asia and North Africa, one of several species of mice in the genus Apodemus; Field mouse, in North America, a vole, such as: Meadow vole, a North American vole; Field mouse, in South America, one of several species of mice in the genus Akodon
The wood mouse (Apodemus sylvaticus) is a murid rodent native to Europe and northwestern Africa. It is closely related to the yellow-necked mouse (Apodemus flavicollis) but differs in that it has no band of yellow fur around the neck, has slightly smaller ears, and is usually slightly smaller overall: around 90 mm (3.54 in) in length and 23 g in weight.

The short-tailed field vole, short-tailed vole, or simply field vole (Microtus agrestis) [2] is a grey-brown vole, [3] around 10 cm in length, with a short tail. It is one of the most common mammals in Europe, with a range extending from the Atlantic coast to Lake Baikal .
