Latin: Apodemus flavicollis.
The yellow-necked mouse is dark brown on the top side, while the underside is pure white, except for a brown band (collar) in front of the front legs. It is larger than the house mouse, head and body measuring 10-12 cm, and the tail is slightly longer than the rest of the animal.
It is primarily associated with forests, but is also common in gardens with many trees and shrubs. Most of the year they stay out in the open, and the ones that invade houses do it towards the end of October. The yellow-necked mice continue to seek inside through the winter, apparently as the food in their natural habitats disappears.
