In the garden

Yellow necked mice feed primarily on tree seeds, fruits, some green plants and invertebrates; the diet is very similar to its cousin, the woodmouse.

They are locally common but only found in restrictive ranges in Southern Britain from Dorset and Kent, up to Suffolk and also in the Severn Basin from Gloucestershire to Staffordshire. It is unclear why it only exists in these regional areas, but may be to do with climatic factors, possibly showing an aversion to wetter, less sunny areas.

Although it is believed to prefer mature woodland they have been known to turn up in hedgerows and gardens, having nests either above or below ground with extensive tunnel systems and several entrances
