Ecology
The Libyan jird may live alone or in small colonies, and is more sociable in winter when colonies may contain twenty or thirty individuals. It inhabits a burrow up to deep which is a fairly complex series of passages with multiple entrances; an empty burrow of the great gerbil

(''Rhombomys opimus'') may be used. The Libyan jird is a diurnal species and forages for seeds, bulbs, tubers and leaves, as well as any dead insect it may find. It often carries the food back to the burrow and here large quantities are stored in chambers near the surface, deeper burrows being used for nesting. It is opportunistically migratory, moving to new territory when food becomes scarce. Breeding takes place throughout most of the year with several litters of about five young being born.[
