This Wee, sleekit, cow’rin, tim’rous beastie is the St Kilda House Mouse (Mus musculus muralis). This specimen was found on the remote St Kilda archipelago off northwest Scotland, 41 miles west of North Uist in the Outer Hebrides. The St Kilda Mouse, now extinct, evolved from introduced house mice but it was larger than the common house mouse and is an example of the phenomenon of island gigantism. The human population of St Kilda fell to 36 individuals in 1930 and they requested to be evacuated. After 8 years of survival the St Kilda Mouse became extinct because of their reliance on human habitation for food.
