In terms of their appearance and way of life, they are very similar to squirrels and are classified between mice and squirrels.Due to the favorable climatic conditions and the expansion of industrial and agricultural activities, especially the cultivation of olive trees, walnuts, hazelnuts, etc. in this province, a suitable habitat has been provided for these rodents.The main habitat of this species is coniferous and deciduous forests, orchards and in basements and mountainous areas.
