Harvest Mouse – Micromys minutus
Breeding nests are the most obvious sign indicating the presence of harvest mice. The harvest mouse is the only British mammal to build nests of woven grass well above ground. Nests tend to be found in dense vegetation such as grasses, rushes, cereals, grassy hedgerows, ditches and brambles. They are generally located on the stalk zone of grasses, at least 30cm above ground in short grasses and up to a metre in tall reeds. The size of the nest can vary from only 5cm in diameter for non-breeding nests to 10cm in diameter for breeding nests.
Harvest mice have many predators: weasels, stoats, foxes, cats, owls, hawks, crows, even pheasants.
