Life History

They nest wherever there is cover and warmth, usually below ground but they can also be found in hedgerows, buildings, etc. It has 3 to 8 young (average is 5). The gestation period is 25-26 days. The life span is short - usually only a few months but it may survive longer. They are generally nocturnal animals with superb hearing and vision (hence the large eyes and ears). These mice are primarily seed eaters, relying to a great extent on the seeds of trees, but will also eat berries, invertebrates, worms, carrion and other similar food.
