Found dead in a cornish hedge.
No interactions present.
I agreed with Gill at first because, this being a young animal it is impossible to separate the two species; however, I've also agreed with you because I've just noticed where you are and Yellow-necked mice are not known from your area. That does not mean you have none it could just be they are under-recorded as they are so similar to wood mice - though chances are it is a wood mouse.

Thanks, but how could I make a clear identification if there are so many possibilities? The person who found it with me said it was a wood mouse and he is quite knowledgeable about such things though at the time I forgot to ask what features led him to identify it as a wood mouse...
The main way to separate the two mice is yellow-necked mice have a continuous yellow band across the chest from shoulder to shoulder. Some juveniles have a continuous grey/yellow band, but not all. However, wood mice never have such a band though adults can have a yellow smudge on the chest. Even experienced small mammal experts can make mistakes with these two; the problem is very few of us have seen enough yellow-necked mice to be absolutely sure with some animals, me included.
