It is unknown how animals regulate their foraging behavior in presence of mirror image and video of conspecific individuals. Here, foraging behaviors and time-budgets of ICR mice (Mus musculus) were tested in presence of a conspecific individual, a mirror image, conspecific video or non-competitors (control) within indoor enclosures. ICR mice tended to move foods to the area with low competitive risks for hoarding in presence of conspecific individuals, whereas they spent more time touching and staying with a conspecific individual than with the mirror image or conspecific video. These results suggest that ICR mice adopt different strategies of foraging and time-budgets under different conditions.
