Wood mice remain active all winter, relying in part on caches of food laid down in autumn. Don’t be fooled by the name. Apart from on a few Scottish islands and mountains, you can encounter these endearing nocturnal rodents, also known as field mice, just about anywhere. They’re more than happy to share our homes, so just because a mouse is indoors, that does not make it a house mouse.
The best way to tell the species apart is by the ears, which are much larger in wood mice.
