Abstract: Lay Summary A foraging game takes place when a forager has to take other foragers’ behavior into consideration. We find that such a game exists between competing gerbils and jerboas, with both foraging more when hungry and hungry jerboas foraging more when gerbils are also hungry. Gerbils attack jerboas more often when they are full or when jerboas are hungry, which may be attributed to a balance between resource protection and immediate consumption.
